The 318 is a god of an engine. It always seems like it's "Get rid of the 318 and go 360 blah blah blah" the 318 is already internally balanced and revs to the moon.

I think the reason the 318s were never seen as a performance engine is the fact that it was never allowed big valve free flowing heads or much compression in most cases. The 340 got these so it got the spotlight and respect it earned. The power for any brand is mostly in the heads and cam anyway. If you built a 318 and 340 identical other than the cubes you wouldn't see all that much difference. Nice video. 👍

I grew up in the 80s, when there were still enough 60s and early 70s American cars around that we could afford to be partisan when it came to brand loyalty. For instance, from 1985-90, I knew of a bunch of people who owned at least 7 different '68-'74 Novas, and at least 6 or 7 different 68-72 Chevelles. Because I've always been a fan of the underdog, and because there were so damn many Chevy cars around, I became a Ford/Mercury fan. But nowadays they are ALL few and far between, so it's no longer practical to be so partisan. Now I'd gladly own a '68 Mustang fastback, a '68 Cougar, or a '68 Firebird, a '68 notchback Barracuda, a '68 Charger, or even a '68 AMX(but with just slightly less enthusiasm for that last one).

Great channel, it brings back a lot of memories. My first car was a silver 1967 Barracuda "Notchback". It came with the 273, but since my parents were into drag racing, that was soon changed. After the 340 we put in dropped a rod, we had a 318 that had been in our Pro Street car sitting around. It was bored 0.60 over, had 13.5: 1 pistons, aluminum rods and a high lift cam. Needless to say it was the fastest can in my high school. Those were the days!

I used to beat 383 Roadrunners with my 65 Dart 273 Hi-Po! On the street of course! It ran 14.70's stock. You put good heads and induction on any 318 bored out and they'll scream! It's all about lbs per cubic inch all things being equal. I used to race a Super Stock 340 Duster in the 70's.

That guarantees hundreds of extra hp! 😁 Just kidding of course.

@@mikewardhvacrestoration7136 A mildly built 318, WITHOUT a stroker crank, will put out a solid 400hp! Stock 340's were rated at 275hp and really put out 310hp-325hp. Good heads (Edelbrock), cam (.500+ lift) and KB-167 at 10+ to 1 and the only thing lacking is 22 cubes, and that can be overcome by the better flow and higher revs.

When I worked on Mopars in the 70's, hopping up 318's with junkyard 340 parts was very popular. Also, the 383/440 parts also interchange.

The 1967 and, "early" 1968 318 cylinder walls are thicker and thick enough for a 4.00" bore. The same casting was to be used for the proposed 1967 331 cubic inch engine for the Dodge Dart. The performance of the 331 was disappointing, so the engine was scratched and the 340 engine developed for 1968. Because Dodge had planned for the 331 engine in the 1967 Dart the 383 engine that Plymouth offered in the early 1967 Barracuda wasn't available in the 1967 Dart, until very late in the model year, with the 1967 383 Dart GTS. The 340 engine took the 331's 4.00" bore to 4.04", made the intake ports the same size as the 327 Chevy intake ports and made the valve sizes the same as the 327 Chevy valve sizes. The 340 was originally designed for a 6,500 RPM redline, but it was decided that forged pistons would be desired for that RPM limit, but they would be too costly. The 340 had its valve springs crippled to restrict the redline to 6,000 RPM, in order to safely use cast pistons and keep costs down.

@crankychris2

Mopar engineers didn't use forged pistons in any 60's engine except the 426 HEMI. Cast pistons have some advantages over forged pistons besides costs. With a set of Direct Connection valve springs, both these small blocks can rev to 6500 rpm's during WOT application. If your hunting for a used 318, look for a 'Magnum' 318, used in Rams, Cherokees and Dakota's from 1992 to 2003. This upgraded engine was rated at 230 hp/295 ft lbs tq stock and has better heads and other good stuff. --70 yr old Mopar gearhead.

I built a 318 back in the 80s, only 10 thou overbore, not stroked or any other cubic inch mods. The power was a result of the porting, valve grind topped with the standard edelbrock and 750 Carter and 3 inch exhaust made an honest 350 rear wheel horsepower. Had to use a turnbuckle to stop motor mount breakage. Bullet proof engine just make sure to use at least a 3 core rad as these do run hot.

Still miss my 77 van with a 318. We put 340 heads on it , direct connection purple cam, 4 barrel with intake.. don’t know the power levels it had ( i was a young young lad ) but I had headers and side pipes and it was the best sounding small block i ever owned … salute !

Currently have 340 in my 73 challenger and looking to pick up a 96 dakota with a 318 magnum. Great comparison and i think they’re both great engines.

My last hot rod 318 was in a 71 Duster . 3speed manual. At the time it was just about the same time the Edelbrock Performer Intake and cam kit had come out . A lot of work performed but Wow, that car was very stout. Pissed off a lot of people . Now I have a 74 Duster. Probably going with a Magnum 318 just due to a availability of junkyard parts if need be . Nothing wrong with that engine, numbers tell the tale.

318’s are freaking awesome, I have a stock stroke 318 bored 60 over in my car and it’s putting some serious power down guys. Don’t underestimate the 318!!

Lol I wish I had a penny for every time I’ve heard the word “only” in front of 318. Thanks for laughing at those folks for all of us with only 318s.

I personally can give a few numbers as I purchased a pretty decent 70' 340 4spd Duster for 500 bucks back in the 80's with a bad motor. I salvaged what was useable( everything but the block,pistons& crank. I had a 318-3 short block from a 2ton flat truck that I sent out for cleanup,cam bearings and freeze plugs but that's about it. I put in a few Direct connection( remember that?) valvetrain parts like a 284° 284° cam and proceeded to run 13.07 with it on street tires!

You left the threaded windage tray main bolts in the #2 and 4 mains. That clinched it for me. Great points friend, but not so loud. We get running roller 318s for $100 up here. Don't want the wreckers jacking their prices up to match what they charge those poor Chebbie guys. I always rationalized that it cost the same to build a 360 as a 318. 340s were too valuable to thrash on the street or strip. Heck I remember Cordoba owners trying to pay me to drag away their 360 Cordobas. My next build is going to be a 360 long block using later 318 "302" heads for more low end torque in a heavy daily driver. Not sure which cam yet. Have several good Thermoquads to choose from, but I might even try running a Holley 2280 as I get great mileage with those. Your don't have to turn much more than 4000 rpm in the gears with a street 360, thanks to the torque. Great job Malcolm Ottawa Valley

I'd love to say that "it's just a little 318" ! Hell, I've heard stock 318s sound really good with open exhaust. Add a small cam and I would imagine it would sound awesome.

Nothing wrong with a 318! I took a stock 160hp 2bbl 318( on my dyno) and installed a GT-45 turbo. It made 520hp&633 ftlbs on my dyno. Very tough motors, 45 Dyno pulls with no issues and then it went into my 81' W-150.

Turbo on a two barrel … interesting.

Just makes sense. You opened my eyes! The block is the foundation. The assembly is what make the motor.. Got a cracked 340 short block and a spare set of X heads.. A 318 block would make a cool sleeper motor!

Built the original 88k mile 318 in my Valiant. I didn't want to, but the factory machining was horrendous. So, since we were there, it got forged I-beam rods, KB pistons, and a '70 340 crank that was lightened up for the lighter reciprocating mass. The deck were so slanted to the back, that to level it out, the CR shot over 10:1, and thats with '90 "308" open-chamber heads. Had to put 0.060" thick Cometic head gaskets on it to get it down to 9.45:1; with this & a little head work, this little 5.2 revs right up.

In the late 90s I ran a duster with a w2 headed 318 with pretty much the same cam you're using it impressed a lot of people hearing that thing roar to 8500 rpm.

Now if you think about and do some research you can apply the same thinking to 440/426 wedge vs 383/400 wedge both have their strong points and both have their weak points but the later blocks where stronger but made of a slightly softer iron still to me I love all the Mopar V8s!!

I've ported 318 heads as well as the police 4 barrel manifolds in the late 80s to get as much of the original 318 potential, along with a Direct Connection camshaft. Performance was certainly better than stock but it could not compare to a similarly modified 340 even with the extra cubes taken into consideration. In other words though the bottom ends are designed the same except bore size the main difference has always been the induction and I believe that's largely been understood in historic comparison. People never said the 318 wasn't a stout engine, on the contrary. But for a long time you could take your stock 340 long block (aftermarket had little to offer) and turn it into a street/strip competitor. You could not do that with a 318 without the extra time and expense turning it into a hybrid but even at that, good luck. Today, the aftermarket has plenty to offer to turn a 318 into a solid performer.

These 318's are tried and true engines. Very under rated. Most say, pull the 318 and put a 440 in. Yes, very true. However, I never did that and was always happy with the way engine runs. Pulls the Coronet well.

Rods in the 340 are heavier than the 318. 318 heads and intake have smaller runner ports and it's a bad idea to try and mix the intakes.

Get your compression up as much as you can. make sure you put a set of headers on them. It's all about air flow.

Motor mounts on 273-318 are the same on both sides but on the one side the 340-360 use a different mount as they are closer. On the 318 I use icon ic845 - 040 pistons with a 360 la head and it works very well.

You can most certainly install 2.02 heads from a 340 on a stock bore 318! They clear fine! You cannot however install 340 heads on a 273 without notching the bores!

You can actually bolt a 340 head with 2.02 intake valve on a 318 but the bore is .060 closer to the valve so it flows less and since you have less cubes and less flow it makes significantly less power.

Nick's Garage, Mopar man extraordinaire Dynoed a 390 "318" It had over 500 ft lbs and 450 HP at 6500 with no real tuning, he made the pulls only changing the timing slightly, no rejecting even though it was running Fat, so a rejet andNick said hed luke to try a Carb Spacer and oh yeah, Through Cast iron Exhaust manifolds! Crazy power without even trying! I've got a 318 in my 99 Ram 1500 4x4 Ive had for ever, it was a work truck years back, now im Showing it a bit of love. I know I know, it'd be so easy to buy a 360 blah blah blah, i know itd be easy but that means I'd have to pull the 318, find the 360 and probably pull it, take it home and buy everything I need to make the 360 whole xnd right because i wont know it, won't know about maintenance etc I know my 318 and so why the hell not, I don't have to bore the hell out 😞 f it unless I want over 426 cubes, I can build a 390 Stroker and have a shit ton of power without revving the piss out of it which I don't really like doing anymore, I've learned to embrace Trq and a Stroked 318 has a shit ton of it. It's got roller cam so I don't need to run a flat tappet, you can get so so much power out of a roller cam without the big lope because your embracing torque!

I saw that episode. It impressed me. A basic 318 with a double pumper and aftermarket intake. But cast heads and cast exhaust manifolds. A really nice ‘sleeper’ engine.

I got a garage rebuilt stock top and bottom end 86' 318 with a 441 lift cam, 340 intake, stock 302 heads with some port work to match the intake and valve lapping, a Edelbrock 1406 carb, a stock converter in my barracuda with points ignition, 3:23 gears, 26 inch tall rear tires, tf3 shift kit, dual exhaust with massaged Dakota manifolds, idk what power it makes but it fucking RIPSSSS...... Has a welded 7.25 differential too lol

Great Video i love the Mopar small blocks!!!, I want to build a D100 pickup with a 318 I'm in Raleigh NC

When I was a teenager in the late 70s and early 80s, Hot Rod magazine posted an article showing how to build a 330 HP 318. I know that sounds low for HP these days, but if memory serves correctly the build was not that much and it used parts from a 318, 340, and 360. I wish I could find that article… Very good video by the way.

I still have that magazine. There was another one in Car Craft

One of the other big differences is compression. Put some compression in them and they will run awesome! I don't think that the 340 is worth it's premium price just to say you have one. I sold my 340 as I thought the money was better spent towards a 318 or 360. One guy wanted $2500 for his and it was basically a core. I'll pass. They are great, but with today's parts....we have options.

Had a 318 in my '68 Dart. Put the high rise manifold and the 360 heads I pull out of a taxi I found in the junkyard. 850 cfm carb and pipes. Done.

I love my 318. It’s a very mild build and makes 300hp.

my dad had a 318 on a d100 and i saw him driving it without 4 spark plugs, and that shit felt as sweet as candy, very reliable engine, btw we were on our way to bay some new plugs haha

I bought my wife a 67 Plymouth Belvedere II with the original 318. It was supposed to have a 390 ci stroker kit that the soldier (Army) paid for while he was deployed. He paid a shop to build the car the way he wanted, sending them money every month. When I bought it there was a miss and broken motor mounts. Thought it was a tune-up but one lobe on the cam was flat and one compression ring was broke. He got ripped off bad, no stroke kit, no adjustable pushrods, did have the Keith Black Hypeur kinetic pistons. I'm still glad I bought it at a good price with a reupholstered interior and decent body to work with. Wifey likes it!

Thank you for educating me about the 318 versus the 340 block

To me the big dif is the cam they used in the 340 it was a factory hot rod engine. Hell when the concept of the Lil Red Express came about they used the factory purple stripe cam shaft from the 340. The 318 is a damn good engine and they are hard to blow up I tried in my '80 ramcharger and that engine refused to let loose.

The long rods are easy on the cylinder wall. At any speeds.

318 is a great motor. It was Chryslers bread and butter and had to be above all else, reliable. Give it a little love, a very impressive little motor.

340 have little more nickel in the block bushed rods and 67 to 71 had forged pistons but basically the same block. What I think make the 340 is the bushed rods like the hemi and of course the heads

I’ve got a 318 in my daily driver 1970 Challenger. 310k miles and the short block has never been apart except for the timing chain. Smokes a bit but it’s still going strong. I have a 340 block to build one of these days. I’m thinking the value of the car will be worth more with the 340 not that I’ll ever sell it, and the 340 4 Barrel emblem on the hood will be cool. But rebuilding the 318 is tempting.

Mopar '302' High Swirl Cylinder Heads: The small chamber of these heads give your 318 a higher compression ratio, which is good for both power and fuel economy. If you need to build a low compression engine, these are still the best heads to use, but run them with dished pistons. Some builders report that for two otherwise identical engines (including compression ratio), an engine with dished pistons and small chamber heads can make as much as 20 horsepower more than an engine with flat top pistons and open chamber heads. The best intake by far for a 318 running "high swirl" cylinder heads is the Weiand 8007 Action Plus Intake Manifold. Running a large port intake with 318-style ports causes a "damn" in the intake path where the intake mates to the head because of the port mismatch. Most intakes designed for the 318 ports are economy-type manifolds that aren't really intended for high performance. The Weiand 8007 Action Plus is the only high-rise, high-performance intake designed specifically for the 318-sized intake ports. I have one on my Barracuda and I love it. If you're running 340/360 heads, the best intake is probably the Edelbrock Performer RPM (don't run it with 318 heads though). I really interesting option would be the single plane 2-bbl intake manifold that Mopar put on the 273 and some early 318. I think that with porting and Extrude Honing this manifold could be made to flow pretty well. Combine it with a tuned over-size 2-bbl carb from one of the low-end big blocks and you'd have one heck of a sleeper. 318 can be stroked to 348. This is a very cool modification to the 318. It's even easier now since Scat makes a 3.58" stroke crank that drops into the 318 (as well as the 340) without having to grind down the main journals. Or, stroker 318/390 kit! Enough for now..... Cheers

That was very useful didn't know that it could be bored .090 over. Whay size crankshaft did you use and was it a stroker or stock forged?

Built a little rippin 318 in 2012 been a believer ever since !

Love my 87 La 318 . Has the swirl port heads and has over 500,000 miles now . Never been rebuilt . Best 285.00 I ever spent for a engine

I had a nicely built 318 .040 over in a 72 duster with a 4 speed and 3.91 posi.. ..it had a good cam, aluminum heads intake water pump, electric fans, with a serpentine belt system off a late model, and it ran real strong. Beat a lot people with my ruster duster

Great video , how much ,pushing could you get out of a 318?

Had a 318 magnum in my 92 Dakota loved it, you wouldn't believe how good that truck ran.

I had a 318 in a '67 dodge van. It was stock. a real poor boy rebuild. I installed the Heads, 4 barrel intake and Thermo Quad off of a 360 Magnum. It was a good engine for many miles An amazingly quick little van.

318 is the best V/8 ever made, and I am a Ford fan, however I wish Ford had made the 318!

The bigger bore matters for getting good airflow into the cylinder. Other than that there’s nothing wrong with the 318. But don’t ever think the exact same combo in a 340 won’t make more.

I have a 318 in my 68 Coronet. I love that motor.

Love that car.

These articles about what can be done with low-compression, low-performance, no-respect 318 engines are very interesting. During the 1960's, 318's were marketed as base engines for cars that slant sixes couldn't pull. 318's would get you around, but not in a hurry. Part of this was the legacy reputation of the 1950's "poly head" 318's, which had not received ANY performance attention for about 10 years. It is nice to see that common and cheap 318 engines can be built to make really good power and be reliable too.

I know that I am late to the party, but it was obvious that the unpainted block was the 340 due to the special main cap bolts with the extra boss for the windage tray, that the 318 never used. Fun fact, the main caps can be used in the 1956 Dodge 315, & '57 Dodge 325 Hemi & Poly engines. If building a competition Hemi, then the HiPerf 340 & the 318-3 heavy duty truck engines used caps made from a higher grade material. Some machining of the center thrust cap is necessary for the narrower thrust flanges of the Hemi bearing, otherwise, it's all good. I used only a 318 rear cap so I could use an LA oil pump & drive without any need for an [available] adapter in my mild Hot Rod 325 Hemi. I love my 273 & my 325 Hemi, soooo many things interchange.

Knew a guy back in the late 70's who tried to blow his 318 up so he could get something bigger. He never did. Been a fan ever since.

My old man had a 318 in a old satellite wagon . In 200,000 miles he only needed to replace timing chain , water pump & radiator aside from normal maintenance. Rain or shine & summer or winter - she always ran

I had for two or three years a new 1967 Dodge Polara Station Wagon with a 318 V8 engine. It had the quietest and smoothest engine I have ever owned and that includes a comparison with a later Jaguar 5.3 lire V12. I have read many times that owners consider them to be the best Mopar engine ever produced and I certainly agree with that. John Perry, Vancouver, Canada.

You answered my question on the engine temp with it being bored so far out. But it looks like it has a lot of meat between the cylinders. Thats a good thing.

I picked up a X race block. Cast on the side was 318 and the engine came out of a 6.60 1/8 mile car, with W2 heads. Still has a 3.91 bore. I ran a 340 with so much rust I had to bore it .060 so a 4.10 bore for a decade in a street car, weekend warrior drag car 7.40 on the motor, and 6.90 on a 100 shot drove it to work 30 miles many days Anyways the X block will be a stroker engine soon, and a comfortable bore size of 4.04 initially is my plan, and a 4” stroke, maybe 4.100

I was seventeen years old and bought my first new car. My parents found out I was gonna get a road runner and that was the end of that. So I settled for a 73'plymouth duster. But I went back in special ordered it. I put in Fold down rear seat. Fold down center armrest Bench front seat. Bought it in baby blue with a blue outside. I changed it to cordoba metal flake about fifteen coats of paint. I worked in a body paint job. That took me Over a month between dry time. I bought it with a 318 stock motor 2 barrel carb. But the rear was a sure grip 3.23 rear. No 2.76 stock rear. Added heavy duty suspension. Power disc brakes, power steering, sears push am/fm stereo with front and rear speakers. Chrome baby moons and anodized trim rings. Double white painted pin strips. Flipped the lid on the air cleaner, new lifters. New spark plugs , better distributer cap, new wires to the plugs. Plus got rid of the 2ply D78 bias tires, to FR70 radials. It could lay a twin patch of rubber if I wanted 20 ft. Just a fast car. Really fast and good for it's day handling. Loved that car.

I had a 74 Dodge pickup with a completely stock 318 in it I used it hard hauling firewood I would fill the box plus put a heavy trailer load behind it it never ran short on power!

The first year of the LA 318, 1967, the Barracuda had a 383 option to compete with the new 67 390 Mustang and the Dart was supposed to get a 4 inch bore, "331" engine to compete with the 327 Chevy II. The 331 was supposed to be a high performance engine, but Mopar was embarrassed by the performance and scratched the 331 engine and went back to the drawing board and came up with the 340 for 68. The 67 Dart did finally get a 383 at the end of the 67 model year, but the Barracuda got the 383 from the beginning of the 67 model year. The 67 and some early 68 318 blocks have very thick cylinder walls, because the same block was to be used for the 4 inch bore 331. The 340 was developed by boring the 331 the Mopar maximum overbore of 0.040". The 340 intake ports mimicked the dimensions of the Chevy 327 intake ports. The 340 exhaust port were opened up as much as possible. The 340 valve size mimicked the Chevy 327 valves. Originally the 340 was designed with a 6,500 RPM redline in mind, but Mopar didn't want to risk that with cast pistons and dumbed down the valve springs and called a 6,000 RPM redline. The 68 340 manual transmission camshaft had 22 degrees more duration at 0.050" lift than the automatic camshaft. Due to the 6,000 RPM limit, the 69 340 only got the automatic camshaft.

You are right my first car was a 69 satellite with a 383 Roadrunner Hood with a 318 in it every thought I had a 383 in it. Ran so good

As a geezer now I knew even back in my day that along with the iconic sbc come the end of the world there would still be slant 6's , cockroaches , and 318's .

Hey Gary's garage, what is your build list for a 90 over 318 to run as a daily driver?

I had a 70 340 Dart and when we tore the motor down we found that the wrist pin keeper in the #8 cylinder had failed and the cylinder wall was scored badly. Had to sleeve #8. Seems to be a fairly common problem. Saw a video recently where a guy used a 360 crank I believe to stroke a 318. I'll bet that motor was a little beast!

The "original" 318 was a truck engine - and a passenger car engine. I believe Chrysler kept making the Poly 318 for several years in trucks after the LA 318 came out. And, AFAIK, they made the 273 into a "318" due to the reputation the poly motor had acquired as a tough-as-nails engine. That let them go seamlessly from one model year to the next still having a "three eighteen."

318’s can make amazing power with the right work done. Back in the. 80’s & 90’s they were cheaper to build than a 340. I ran one in a duster back in the late 80’s with 390 gears and a torqueflite. The car ran consistent mid 12’s with mufflers and Mickey Thompson street slicks. That wasn’t bad for the day, running premium no-lead. It was very streetable.

Did they differ at all in the metallurgy? Higher nickel content maybe? Just a thought. I drove a 318 for awhile. It was a very good motor.

My 1967 dodge truck has a 318, best engine Ive ever had. Whet I found most interesting about the engine is that the engine oil keeps its new color for 6 months+, the engine runs cool in summer.

I think the trucks still had the Poly 318's in '67.

One of if not the most underestimated engine ever made especially from The 68+ era when the LA came out. I think the intent of the 318 is essentially the intent of the gm 305 and olds 307 but the 318 craps on them. Funny thing is I would say last 5 years maybe and definitely last 3 years LA 318s have gone from scrap price, or free or $50 bucks to now 2022 they demand or get $150-250 easy Also with regards to the rods on early 318s 68-71 truck 328 used same rods and bottom end as 340. Both had same stroke but if u find a 318 out of a van or truck and I believe 2wd also not just 4wd all had the 340 rods. Years ago before we had money and when this crap was still at junk yards that was how we could afford HD rods on our 318 stick cars when we wanted to keenthe rpm’s up Today if you have the money and the motor and don’t need the 360 or can find one as they aren’t cheap either and 340s are essentially going for restoration prices about 7-10 fold a 318. 2 for sale here in ct both 4 barrel motors 71/72 and asking 1500 for one and 1800 for the other. At that point gt a big block or Eagle makes a complete 318 stroker kit balanced with 30 over slugs turns that teen to a 390 and standard bore 384 for right around 2 grand give or take few hundred pending deals and or promotions Mancini racing sells it as does jegs and summit and considering their forged pistons ($450-500 summit) and eagle h beam rods ($550-700)it’s a steal. They already have the height (piston height calculated) and pending your deck height they sell sets from 9:1 all the way up 10:1 or 10.25:1 compression. And that includes a new Mopar Performance 4” hi Po crank. By the time u send ur crank out to get it mag fluxed, straightened which is easier then u think, turned it polish and tanked your prob gonna be at least 250-400 in a stock 318 crank. Just something to consider and by ordering the highest compression kit they make even if you add 360 LA heads you will be way way way above the 7.3-7.5 compression 75cc chambers and stock deck height does to a cast flat top 318 motor. My buddy used this kit on a budget (totally cheap build) and didn’t bore it had 3.91 slugs hi comps with the 4” stroker and iron 340-360 j or x heads he still had a calculated compression of around 9.3/9.5:1. Stroke and piston height really make a difference. We built that motor about 3-4 years ago for his ram Gen 1 and it’s still goes like a raped ape even with a NP435 trans and granny First. He’s essentially driving a three speed. Starts in second Never dynoed but similar builds in engine masters, power nation and tech articles As well as speaking to Mancini with stock 360 heads a 230-240 cam with 475-500 lift or something like a xe268 or xe274 makes 375-400 hp and 425-450 tq. Being conservative pending ur tuning ability and intake choice. I prefer torkers live single planes especially with a stick and I can afford to lose bottom end and raise the torque curve but that’s me with a 4-5 speed and 3:55 bare bare min with 4:11 optimum minus Highway speeds and a great compromise would be something aftermarket in the 3:73-3:91 range. Just a thought if someone is building a 318 consider the cost to recondition rods, new hypereutectic minimum or forged pistons preferred Then the crank machine work and bearing and you might as well add 72 cubes and close to an extra 100 HP With eddy heads they make 500 horse and 525-550 torque which is insane for a SB But that’s another 21-2200 bucks. Just a thought

I certainly miss my 73 340 challenger, unusual car around then. My brother had 340 duster also, plain, nondescript 4 speed sunroof car. We had 318s in other dusters and 273 motors. Love them. Not part of the herd

You are correct to point out that the 318 and 340 blocks are almost the same but the main difference between the two engines is the heads and as a result, cost. If you're starting with nothing you're better off buying a 340 because the cost of new heads and boring-out the 318 exceeds the price difference. Then again if you're starting with nothing you're better off with a 350 Chevy because you get more for your money and I'm a Ford guy saying that.
