Although the one that started it all is already considered relatively old, no one could have predicted the impact the original Gen III LS1 would have on the hot rodding public. The LS1's greatest asset is its revolutionary 15-degree cylinder heads, which are capable of flowing over 320 cfm in the hands of a skilled porter. So good were these castings, in fact, that it took the aftermarket over five years to even attempt to top the factory design. Simply massaging the stock heads and swapping in a larger cam had LS1s easily approaching the 550hp mark in no time. Furthermore, bone stock LS1s routinely pushed F-bodies into the 12s. While LS1 F-bodies were rated at 40 hp less than their Corvette-spec brethren, they essentially produced the same power despite minute differences in cam specs. Likewise, all '01-04 LS1s were upgraded from the factory with the same valvesprings and high-flow intake manifold as found in the LS6. One of the biggest drawbacks of the LS1 are its thin iron cylinder liners that can only be bored about 0.010 over. Anything larger requires re-sleeving the block with aftermarket liners, which isn't cheap, but doing so enables displacement figures well in excess of 400 ci. Likewise, the standard 3.900-inch bore isn't compatible with the latest and greatest GM L92 cylinder heads. Nonetheless, the original LS1 provides more than enough power potential for the vast majority of hot rods, and there are still a ton of them available in salvage yards ready for plucking.
The first of the Gen IV small-blocks, the 400hp LS2 was first unveiled in the '05 Corvette. Compared to its LS1 and LS6 forbears, it boasted a larger 4.000-inch bore while retaining a 3.622-inch stroke, which bumped displacement to an even 6.0 liters. At its core, the LS2 resembles an enlarged LS6. It utilizes LS6 cylinder heads, as well as an '01-spec LS6 camshaft. Subtle differences include a larger 90mm throttle body (75mm on LS1/LS6), a higher 10.9:1 compression ratio, and a different intake manifold. Interestingly, the LS2 intake manifold features slightly greater plenum volume and recontoured runners, which actually flows less than the LS6 intake. For hot rodders, one of the key advantages the LS2 has over its smaller-bore counterparts is that it's compatible with the highly desirable rectangle-port L92 cylinder heads.
All you do is pop it off, lol.

Ls7 with a supercharger put that in a better n see what it gets ya lol the 4.8 with a set of twins wud be alright too
1963 Fuel Injection Unit is best design with 327 or 350 or 383 or 400
LR4 from the junkyard with a home built turbo system
Would love to drop that into my 03 Z71
454 LSX- w/ TT's would be nice
Single turbo 408 LSX. Iron block, nice thick cylinder walls, priority main oiling, 6 head bolts per cylinder, dowel pinned mains... Perfect for big power and heavy abuse. An ERL 427 Superdeck I would be my choice on the aluminum block side of things.
Can I get that swapped into my burban
Any 4th gen camaro owners? Join my group here on FB (Fourth Generation Chevy Camaro owners) it's the one with the guitar icon
A evo 8 ls3 swap :)))) haha haters gonna hate. I love my awd cars and mt chevy motors
one that makes about 750 hp
I like the LS-7...got one that's still in the crate sitting in my dads shop. Got a dyno sheet that says it turns 555 HP and 597 ft-lbs of torque when using a holley 850 cfm carb and hooker long tube headers. Great motor with alot of power!!! Wanted to put it in my 64 nova but it would just twist my frame if I didn't put a full cage in.... long story short is the LS-7 is one bad engine for performance.
Either LS7 twin turbos or LSA twin turbos
I love the LS1 in my C-5. Corvette. It's stock and performs when I need it to. For a sports car 18 city is pretty good when I baby her. Not often enough.LOL
