The mid ‘90s LT1 engine will forever be one of my favorites ever produced. When the LT1 debuted in the Camaro/Firebird in 1993, it was a game changer! Just shy of 300hp and a 6-speed tranny….from the F’n factory lol. I upset a ton of 5.0 Mustangs back then with my ‘94 Z28…. and I was a Mustang guy at heart, but those F-bodies were an absolute riot to drive!

Tons of potential also. You can build a 90s Camaro up to run 11 seconds 1/4 mile times without spending too much money. Good cheap platform for building a hotrod back in the day. I'm a corvette guy, though, and I can still appreciate the potential of that car....

So cool to learn the history of the LT1 engines. During the 1970's, I was riding shotgun in my aunt's 1970 Classic White C3 Corvette Stingray coupe with side pipes. My hometown is near the Bowling Green assembly plant. My first visit to the Bowling Green assembly plant was on a school field trip when I was 10 years old. In 1989, I drove my uncle's 1989 white C4 Corvette to senior prom. My aunt and uncle both had automatics but my best friend's mom had a Monza Red Corvette Stingray with side pipes and a manual transmission. Watching her row through the gears had me hooked on manual transmissions. I took delivery of my very own 2015 Arctic White C7 Corvette Stingray Z51 manual 7 speed, on February 13, 2015.

My 96 Buick Roadmaster sedan needs more torque but I can't afford to waste money on parts unless they really work. By the way my engine has about 160,000 miles on the factory Opti. I'm surprised it survived a water pump change before I really knew anything about it. I have a new Opti I'm gonna use for parts to rebuild the original, since the original trigger/pickup or whatever it's called is better.

I appreciate the explanation on how the direct injection was able to run more compression and not get into detonation. More pressure over the piston makes more power

I'm a Ford guy but to me the Chevy gen 2 was one of my favorites that GM made. It make good power and responds well to mods. A great street engine. Plus has a clean look. It's one of the nicest looking engines out there. Still the best looking swap engine in my opinion. Although I like the L31 vortec(better build platform) for the better heads and the 4 bolt mains as a plus. That 6.2L is making HOT 408 stroker build numbers to good 427 stroker numbers, in a package that can be driven everyday, impressive!!

I'd definitely enjoy seeing a 1995 or 1996 LT-1 build with part numbers / grinders for the cam, and most importantly, how to tune the fuel injection, and ignition after the cam change .

It is amazing that the Latest LT1 can make so much more HP and torque than any of it's predecessors. I've been told in the past that the heads control how much HP the cam can make.

The port design of the LT series engines is based loosely upon the LS7 head port design, and that's the best flowing LS head PERIOD. Given the stock power, I don't see why a heads/cam/VCT delete LT1 can't make 700hp N/A.

I love this comparison but I feel the older motors would have had a better comparison to the ls1. Keep up the great work.

Great work. Thank you.

The LT1s were known to Dyno out to 360HP, why GM underrated them is unknown. Of course we know GM wasn’t gonna allow a Camaro to rate the same as a flagship Corvette. Politics! I also agree the 5th Gen LT-1 is not the same as the original small block Chevy, so not really a comparison in my opinion. Good video and another thing to prove to those that put the 2nd Gen LT1 down don’t know what they are talking about 😉

My brother and I stuck a early LT1 in my ‘69 GMC 1500 2wd with a three on the tree and 3:73 limited slip diff. It would spin into third even with MT L60’s on the rear and I never found top end! The fastest I ever took it was the speedo all the way around and back to 20! Anyone who might doubt this can ask the girl I was trying to impress and my friend who told me it was time to slow down! Lol! It’s a bad feeling when the front end is floating!

Hey thanks Rich I would like to see more GEN II LT stuff intake manifold, throttle bodies, cylinder heads, cam shafts I know you have mentioned you've ran a fast controller on one. I would like to know more about that. I've owned a few of these cars never had an issue with the opti spark. had well over 100,000 miles on one that had two water pumps puke on it still never failed. I've only changed cap and rotor, maybe I,m lucky. Only issue I see is RPM range I don't really take em past 6000. Anyway I appreciate all of your work...Keep testin I keep watchin

I went with a '70 LT-1 clone for my '70 C10 because I wanted to keep it all old school. But those LS motors sure are tempting. I love EFI and built a few systems from scratch in grad school (using a 25MHz 486 PC and hand-wired prototype cards).

Best KZread channel !

I want to see your mid 90s Lt1 video. I like these engines, I think they still have good potential

Love all of them. Especially all that tech in the 6.2L. But....1970 = clackety, clackety, tick, tick, tick SOLID CAM!!! ♥️♥️

I have a 2017 Camaro SS with the LT1 so I was glad you did the comparison. It's rated as 455/455 from factory but i got mine on a dyno after long tube headers, LT4 throttle body and Roto Fab CAI and got 402 at the wheels. Not impressive but after reviewing the data it went rich after 5500 so killed some HP. I have gradually pulled fuel so I would guess it may be around 410-415 now cus it peaked out at 5700 rpm and this engine has way more to go.

Best he’s ever gotten on a stock motor was 398... it was hot & humid as hell when mine was done so I wouldn’t have even been there for a baseline.

I bought my first Corvette in 1972, it was a 1971 LT1, one of my friends had a 1970 LT1 & everytime we raced I beat him, usually by about a fender, he had a hard time accepting the because he had 370hp to my 330hp. Even though it only had 9 to1 compression, it ran really good back in the early 1970's. Right now I have a 1965 Corvette with a 1972 LT1 short block & Performer RPM heads, milled to 58cc, 10.6 to1 compression & it runs pretty good.

I loved it! I have a 92 corvette with Gen 2 Lt1. I will swap the new gen v Lt1 in it asap. Big cam, too! 550hp net... Going with the Tremec 7 speed.

Quick question- you never explained fuel management for gen2 LT1... how were you operating the engine to obtain that rpm runout? Thank you

In 1970 -The 1970 LT-1 Engine in Corvette. Had bigger inch exhaust pipes ,and had 2- Signal Mufflers. In the 1970 Camaro Z-28 LT-1. Exhaust pipes smaller. And the Exhaust went into 1- Muffler,. That was than 360 HP And out tail pipes. That add back pressure, cut down the Horsepower. I have a 1970 Chevy Camaro Z-28. I changed too- two and a half inch round Exhaust Pipes. And Two Mufflers. That put Horsepower up to 370 Horsepower

Have a 96 Corvette lt1 in my 72 Corvette. I put the LTCC on it to eliminate the high voltage side of the optispark, so basically the optispark is like one big crank trigger. I love the gen 2 lt1 as they are always downed and are the red headed stepchild of the SBC.

Thanks Richard, like you I like the old school stuff too.. My father scored a ‘70 LT1 long motor in the mid to late 70s (out of his Boss’ genuine LT1 Vette which had a BB fitted!!) and put it in his ‘69 Holden Ute here in Oz!!! Was an impressive car - even as a 7 or 8 year old kid!! Hard to ignore the technological advances of the Gen V. I was surprised to see a relatively flat torque curve from the short runner intake on the second gen LT1.. would a long runner intake add value in that application ?

Very cool comparo :)

i have a 1996 Z28 LT1. i love that engine, a torque monster. even in stock trim with very minor mods like a PCM tune. the car has 255K on it, transmission redone a couple of years ago with a shift kit and higher stall converter. i have daily summer driven this car since 2014. while the paint is beat, it's still a clean car and i love driving it. it's not worth ALLOT so im just going to keep it and drive it as i have been.

It’s interesting how much torque the Gen 2 LT1 had considering the very short intake runners. It must have really been held back with its camshaft. A huge cam to match the intake runner could really make that little engine shine . It’s too bad cam swaps weren’t popular during the Gen 2 heyday

Longtubes, true duals etc... It went from a good running, fun car, to an absolute MONSTER for an N/A 350 cube small block. Just how it would have run on the track, I dont know. But it certainly had no troubles with any ls1 it crossed back then. Admittedly, heavily modded ls1 cars were few and far between at that point, but it's a good point of reference. Ls's start at an advantage, but the LT1 was certainly no slouch.

Great video & idea. I love the chronological recording of the "LT1" moniker. I've always understood the original ("LT-1")was quite "racy" for its day, much like the Legendary DZ302 was. Solid flat tappet cam, high comp & a carb to match. Awesome! Like many folks had a "Clinton-era" LT1 myself 20 years ago as the LS1 F-bodies were killing everyone & thing in sight lol. Typical stuff on my 30th Anv edition car: mild comp CC-305 cam, Meziere (sp?) elec w/pump (an interesting upgrade to perform, nothing horrible just a little different because of the eccentric sprocket above & driven off the back side of the cam sprocket)bolt-ons, LT4 knock module etc. Very impressed with the EFI LT1 numbers too! Of course the New LT series w/DI is truly a different animal. Pretty amazing stuff though, especially in a world of OHC engines. Nothing against those designs but OHV stuff just always seems to captivate & excite me.

There is really two LT-1 in 1970. I had them both, still have my Vette. With LaMans blue paint! Built on November 6, 1969. Which had one of the original batch made over the summer and the testing on. My ‘70 Z28 on the other hand was built in March of 70! The Difference is: drum roll… Free floating wrist pins in my Vette! NOT in the Z which has a windage tray. The Vette had the Harrison mag pluse T drive distributor. 5 qt. Pan with baffling. So there is a 10 HP difference accounted for!

Try putting the amount of info Richard is in each video into your own and see how much fun all the editing and fact chasing is, let alone trying to create something to appease everyone. ;)

This is one of the better Chevy factory engine shootouts that Richard conducted. The winner is easy to discern, the newer the Corvette engine the more streetable it is. Imagine the LT1 heads with a gen2 TPI intake & roller cam! Add nitrous & you're hitting 700lbs of torque!

Even if you had tested the 5.3 gen V engine, which is the same design as the 6.2 LT1, it would have made just as much power or more than the gen ll LT1. Modern technology is a great thing.

Easiest way to make it fair: Take out the displacement & look at the hp/litre of each motor to see which is better/more efficient. Gen 1 & 2 are around 60hp/litre with their 350hp at 5.7L Gen 5 is over 80hp/litre with almost 520hp at 6.2L. That's around 33% better efficiency over the years. 👍

@@W.A.R.R. I was based off Richards' numbers. I'm not being that asinine to give you each year model, work it out yourself.

@CC Ryder Your response missed the point completely. Engine efficiency has nothing to do with a cars weight. It doesn't matter if the car weighs 2000lbs or 4000lbs, it's what hp/litre is. We're not looking at power to weight. 🤦

The modern one has the higher power at a higher RPM, but is leaner and cleaner on fuel and has stock GM parts availability.

Technology has ruined racing. Even 20 years ago if you could afford a brand new Camaro you had to build it and learn how to race it to compete. Now, all you have to do is be rich or go into debt and your running 12s with a stock mustang gt that drives itsself compared to a fox body.

Agreed 👍

Would love to see a bolt on gen v lt1 vs stock ls7. What's crazy is I think the modern lt1 with a few bolt on will out perform a stock ls7

I always wanted to do the 3 inch crank from the 4.3 in a 4 inch bore one piece seal block. Cant wait for the gen 2 302 build @wringing hands here lol

More of a contrast than a comparison vs the new LT1 being 60 years newer than the sbc. I still like the LS better than the new LT as it's a better balance of modern technology and affordability vs the LT.

I feel sorry for the 1970 . We thought they were fast. Need to do a LS 427 comparison against a 1970 LS7 454.

Don't feel sorry for us... Everything is relative. Things were simpler and a lot more fun back then.

My 95 Roadmaster would run low 14s with almost no performance mods and got 24 mpg at 75-80 mph. The LT-1 was a huge step forward for GM.

Darnell Craig That big old barn door getting 24 mpg at 75-80, I call BS. I have a S550 mustang GT manual shift that will get 26-27 mpg at 65-70. It will get 31 mpg at 55. Boring as it gets. At 80 mph maybe 24 mpg. This car is lighter and more aerodynamic then a 95 Buick Roadmaster wagon. I am and always have been a Chevy man and grew up with the small block Chevy. I still have three Chevrolets with a small block and two of the are LT1s

Don Grizzelle the Roadmaster is pretty aerodynamic, add in the OD trans, 2.73 gears and a 30” tall tire. mine was the sedan also. I have a picture of the tach and speedo where I’m going 80 mph and the tach is at 1800 rpm. I owned that car for 3 years total and drove it all over the eastern US. Around town it wasn’t nearly as good but the interstate is where it shined.

70 LT1 360 versus 370hp in Vette, remember the L78 (396) in the vette it was rated 425hp all other variants were 375. I don’t believe there was any difference then either.
