I am Sam, son of Sam. Here's some old cars & engines I work on for entertainment purposes. Also do reviews on hotrod parts, engines, etc. I'm a retired mechanic/engine builder and I like to talk about engines & shit. I do cuss alot. So, if your easily offended, you might want to go watch some cartoons or hide under a blanket. Because I say "Fuck" & "Shit" alot along with other offensive shit. I speak freely. No script. i just be myself. Viewer discretion is advised. 🐍 Have a great fuckin day....😊

I wish I knew of your shop back in 2017. I would have got you to build me a motor instead of ordering a new crate motor from GM. (redline 5800 so I'm OK) The only reason I took that route is because I didn't trust anyone I talked to and don't have the confidence, patience or detailed knowledge it requires . Interesting video as always..Always learn something here. Your living room won't make it on the cover of "Home Decor" magazine but I think it's cool AF. Even the old model cars. I still have mine too.
Thanks man. I have a couple thousand model cars tucked away actually. Still have them from my youth and now I'm old. Also have thousands of old Hot Wheels cars and bunches of other car related shit. Most is boxed up and stored away. Also have around 20,000 car magazines and tech manuals etc. Fills up a small out building. Been a collector of hotrod related shit my entire life. Can't quit. Also collect engines and parts.
l like how someone knew the proper way to add weight on the 496 crank. The one thing my friend was most proud of when he built my engine was the fact it was balanced to zero.
Yep, always put the Mallory in the side of the counterweight. My guy been balancing racing engines since the 60s. Also pulling trucks and drag boats, oval track cars and Sprint cars etc. He's been around. Plus he's a drag racer since the early 60s, he's won class at Indy US Nationals in Superstock back in the 80s and still races a hardcore tube chassis Top Sportsman type 57 Chevy and a tube chassis 67 Chevy 2 Nova Super Gas car. Both fast as hell. His walls are covered with old photos of his drag cars going back to about 1960. He's had a bunch. Probably 75+yrs old. His 50yr old son races too and works with him. The old man drives a Super cool 57 Chevy hotrod to work. It's a 70s style hotrod.
You got good taste man.
Thanks man
Thanks for the balancing information I will definitely balance my high performance engine but I'm not worried about my truck engines that don't turn much over 5500. They've always did good with the stock balance.
No problem man, thanks for watching.
Went to look at a 327 last night. And i came home with two of them!! One complete runner and the other a shortblock 331 with forged trw pistons. Love your videos
Nice score there. Killer old engines. Thanks for watching man.
I own one of these. Haven’t used yet
Pretty good intake. Look kinda weird tho.
Big deal i rather spend time money on legends
Definitely takes a chunk of money and a lot of work, but that old shit is still cool. I'm building a 327 now with 292 angleplug GM "Turbo" heads. They are ported Crane Fireball heads from 1975. Pretty badass heads even today. Gonna make a shitload of NA power.
I have purchased flotec heads had misfiring issues on a windsor hardly worth thr bother 800.00 guids to tight valves hanging up compleat junk
@@user-gi4vu4fu2x Haven't used any of them Flo Tek heads, but I've heard different shit about them. I do have a pair of their bigblock heads on the shelf I've never used yet. But I'm gonna go completely thru them. Bought bare, all good shit going in them and my machine shop gonna work magic on a valvejob. Using Ferrea valves and ISKY springs. Gonna mill them down too. They are the 360cc runner versions. I was looking at their 225cc SBC heads a while back. Looked to be a good deal.
@@thereluctantgearhead4544 thear combustion chamber design blows
Buy chineese junk that misfires at 5500 fucking junk they aint better
Fuck that lol those are 365hp heads right out the factory with a dremmel and a 15 hrs into each head plus sealed power head set w stock springs you could make over 400 net
They definitely have potential. Just look at what the NHRA Superstock 327s are making and running with them. Bad motherfuckers for sure.
Hey chief I’m doing a 327 build for my 59 el Camino, I need some expert advice. I’m thinking of doing a Howard’s roller cam Lift: .525 / .525, Duration @ .050: 225 / 225, Centerline: 106 As well as going with the Howard’s retro fit street lifters. I don’t want to build a monster I just want something fun. My question is what kind of rocker arms should I go with? & I haven’t bought heads yet but I’m thinking either AFR enforcer, Brodix ik200, Promaxx200. What do you think is the best choice heads? I know they are in the cheaper side for aluminum heads. Any other things I need to get? Besides proper length pushrods and a good set of head bolts.
Out off those 3 heads, the Promaxx will make the most power. I own all 3 sets myself. I like to use Scorpion or Harland Sharp rockers with those heads. You could bump that cam up and still have no drawbacks and make more power. Id want to at least run .550 to .600 lift or more to get the flow from the heads. Ports are about a 1206 also, so run a good singleplane intake like a Super Victor or Holley Strip Dominator. I have a Strip Dominator on my Promaxx heads and it fits like it was made for them. I use a Super Victor on my Pro 1s, and a Brodix singleplane on my IK Brodix heads. I'm building a old school drag race 327 myself now. It's going to be a 8000+rpm screamer tho. BME Aluminum rods and shit, 13.5- compression, 272/[email protected], 650/641 lift, 110 lobe separation. Using ported vintage Crane Fireball angleplug 292 heads on it. Either a modified Strip Dominator & 830 Holley or a Holley Tunnelram with twin 660 center squirt Holleys with 1 to 1 linkages. Looking for an old 48-52 Chevy to put it in and build a old school gasser. A 53/54 would work too.
Get adjustable pushrod guideplates for any of them heads. And make sure your springs will work with your cam. 7/16 studs always a good idea too. Mahle .026 thick graphite head gaskets are what I use on a lot of them. Work real well, bore is only 4.125 and .026 compressed thickness. Used to be a Detroit/ Victor Renze gasket, but Mahle bought them out. Believe it's sold as a marine gasket. You'll need 1206 Fel Pro intake gaskets. ARP 134-3601 head bolts are the bolts you should use. Chamfer on the bolt washer always goes up. Devil's in the details.
@@thereluctantgearhead4544appreciate it all the info!! Thanks Boss
thanks
No problem
Seems ITB or dual quads would be the way to go in order to keep things even. I wonder how well these compare to what Ford did with EFI on the 5.0 HO intake.
Offenhauser makes a cool dual quad intake for these engines. Hard to find piece these days tho. Discontinued decades ago.
People want a lot of money for them rare old Oldsmobile intakes & parts these days. A lot of the shit belongs in a museum these days.
Dude your hilarious!

I really appreciate all the good info you gave me. I will keep you updated on the builds. Probably gonna build both motors. Your videos have some of the best info Ive heard. Nothing beats old school NA builds and your wealth of knowledge. Again really appreciate it.
Thanks for watching man, good luck with your projects.
Nice score!.. It seems counter intuitive that having the bolt tubes in there would flow more than a a nicely countoured wall around the bolts. The tubes seem like they would create turbulence. Is there even more milled out behind the tubes so air can go completely around them that the camara can't see? Love your videos. Thanks for taking the time to make them.
Yep, they are opened up pretty big. The tubes don't hurt nothing. These heads flow quite well. Engine made alot of power for 358 cubes.
Thanks for watching man.
These 200cc runners are more like 220+cc now.
You might want to have the intake to head mounting face milled to correct the angle and because so much was cut off of the bottom. Guys usually will have the intake milled to correct the mismatch when it's the heads that are causing it. Mill the heads where the intake bolts on and any intake will now bolt on. Mill the intake and now only that intake will bolt on. Also when you go to use those make sure you have deep pockets. That is deep valve relief pockets because of all the material milled off the heads so your 3/4" race cam will have clearance.(The other meaning of deep pockets helps to😁) Also make sure that the bolt holes were spot faced after the angle milling so the bolt shoulders clamp down evenly. I'm sure you know all this but you didn't mention what it takes to use a set of heads that are altered to that degree. Cool set of heads by the way. Sad that Dart isn't making those anymore, they're only about 15 miles from me. Didn't the company get sold? That's why I think they're doing a lot more outsourcing. George Delorean(John's brother) used to work there, I had a long conversation with him about 10 years ago when he was still there semi-retired. A friend of mine I was building an engine for knew him and had me call him to discuss his engine build. Very cool guy, wish I recorded that conversation.😎👍
Takes alot of work to use these heads, but that's ok, these heads have been finished for years. They were angle milled, then came back and flat milled. So the intake face is correct. I have a few intakes that are milled that will work with these. Big DART singleplane is the one probably going on them. Also have a Super Victor and a couple older Vic Jr's that have been extremely modified and milled. It's good to have 50+SBC intakes. Many already came off similar type engines. I have a set of JE pistons that will work with these too. I found a good deal on a Reath crank, BRC aluminium rods and BRC pistons, all balanced and never used. Guy that was building that engine died and the shit has sat around for years. But with those pistons it will be 14.5-1 or better. Pretty nice shit.
These heads came off a Dirt Modified racing engine that was used 2 races. They already have them pretty sorted out. The original owner spent a shitload of money on that engine. Lots of tricks.
Yep, DART got sold out a few years ago. Believe Dick Maskins died. Now the company is owned by the people that own everything else. Most of the heads they used to sell are no longer available. The new SHP heads are cast overseas. The price on those came down tho. $1200 bucks will buy a new pair of SHP 200s. Pretty good deal. Can't get most of their bigblock heads anymore either. DART ain't what they used to be.
I try to keep my videos at 20 minutes or less, seems most people's attention spans run out past that. So I leave alot of details out that I'd like to put in, but the video would take an hour. Plus I'm usually about to pass out when I make these videos. Generally after an all nighter when I do these videos. Sometimes I'll get into a project and don't stop for 2 days straight. When I start passing out in my chair, I know it's time to go lay down. The older I get, the less I like to sleep.
Was just checking angles and thickness on these heads, turns out the intake face is milled to compensate for the radical angle mill, it's milled about a 1/4 inch above the intake ports down. Believe the head was milled .200 thousands of an inch. So the chambers are actually around 48cc. Gonna run with a .026 thick head gasket and zero deck. 4.040x3.500. Should be around 358ci. It will make 600+hp NA. Might run a 1050 Dominator on it. Going with a DART 4500 flange singleplane intake. Definitely race fuel only. Might set it up to run on E85. Compression will be over 13.5-1. Like to drop it in my Camaro and run high 9s in the 1/4 NA. It'll be a 8000+rpm unit. Camaro weighs in the 2600lb range. I'm currently gathering parts to build a fabricated 9 inch that'll hold 1500+hp, so the sky is the limit. Believe the axle housing tubes are 3/8 thick steel. All gusseted up and shit. It's a monster. Going with a aluminum center section too and 40 spline axles. Eventually I'm gonna drop a bigblock in it, maybe with twin Turbos. I already have all the shit to do it. But I don't think a Australian Borg Warner 9 bolt rearend will handle it. Also have a super stout T-400 to go in it. 3.5 inch custom driveshaft with solid 1350 u-joints. The car has been fast for decades, but I want to take it to the next level. A 1200-1400 hp bigblock will take it there. 20lbs of boost on a 496 will make that pretty easy.
You think it could benefit from floor filling?
Maybe, but the floor is low because so much was milled off the bottom. These heads made over 630hp 11 yrs ago on a 358ci SBC, so they did pretty good as is. They were angle milled, then flat milled. Valves are now at 21 degree.
@thereluctantgearhead4544 i wouldn't leave a spaceship warp drive alone if it was given to me, lol.
How good did the 403 Olds run? I have a 350 and a 425. Looking to build a spicy street car. Its hard to find headers for a big block Olds based G body so I have some work in the 350. I was gonna use the Big block B heads I have but its gonna kill the compression. Would you waste time on 350? I have a set of 6 heads Im trying to port. I know the 425 is gonna be pretty mean. I had a 455 in my last one. You know how pricey these olds are.
I ran mid 7s in the 8th with that 403. Drove it daily too. Used milled J heads and KB pistons. Lunati Streetmaster cam. It was pretty rowdy. 3500 stall & 3.73 gear 8.5 rearend. Just didn't want to spin it too high without a girdle & hardblock. Definitely not as good as the 425 and 455 engines, but the 403 can be pretty good for a Street/Strip type car. Bigblock G-body headers are impossible to find now. I have a pair of Hooker Super Comp swap headers I bought 30+yrs ago, they costed a fortune back then. Now they are discontinued.
The Olds 350 has alot of potential too. I've seen a few rowdy race versions. The 68-72 blocks are the best 350s except for the later diesel DX blocks. They were the stoutest Olds blocks made period. People had them up over 1000+hp in Pro Stock back in the early 80s. Look up Dave Smith. Parts availability is what sucks for Oldsmobile engines these days. And cost.
I ran high 6s in the 8th with a 1966 Toro 425 in a 3000lb G-body. It had alot of work done to it. Secret was the big roller cam and the 12-1 compression. Used ported & milled C heads on it. Cut for 7/16 studs and used SB Ford roller rockers. The stock rods were the weak spot. Ended up bending a rod. Didn't break, just bent the rod a good bit. Had ARP bolts everywhere. I'd turn it up 7000rpm. Stock forged crank was indestructible.
I used a 1966 330 forged crank in my 403, & polished 403 rods with ARP bolts and KB pistons. Engine made around 460hp & 450tq.
I said in the video that they discontinued these heads Jan 1st 2013, but i ment to say Jan 1st 2023. These heads were cast july 23 2013. About 11 yrs old. Dart just pulled the plug about a year and a half ago. They sold those heads since the late 1990s.
Very nice video sam😎🤙🏽
Thanks man.
I had a set on a 406 and it did ok, but the 200cc heads flowed better. These dart clones are pro 1 platinum 200 copies. The old pro1 turned into their shp heads, at least the 200 cc was the same.
I just uploaded a video about a pair of 2013 200cc DART IRON EAGLE PLATINUM heads off a Dirt Modified 358. They are heavily modified. Engine they were last on made north of 630hp & 520tq at 358ci. Pretty hard core. They flow well over 300+cfm & 220 exhaust.
I pretty much have examples of all of them. Been using DART heads since the early 90s.
My 215 Pro 1s are ported and flow getting good. They make 600+hp no problem. Was on a 388ci SBC.
I use a guitar stand to hold the radiator
When it comes to Double. hump. heads, or any old 60s Chevrolet heads. it's not so much about the speed. It's the nostalgia. They look cool. They sound. good. a hot rod is a hot rod And you can still live like back in the day. when things were good.
Yep, that's why I'll always like them. They come from a simpler time in life. Cast iron chunks of history.
Wish it didn't cost so damn much to get them into shape these days.
