The big hoss in LS land, at least for the moment, is the factory-supercharged 638hp small-block that powers the new Corvette ZR1. Not only is the Gen IV LS9 the most powerful engine ever conceived by GM, it easily produces the fattest torque curve of any Chevy in history. While its torque peak of 604 lb-ft at 3,800 rpm is very impressive, the fact that it belts out 350 lb-ft at just 1,000 rpm is downright breathtaking. At its core, the LS9 shares more in common with the LS3 and L92-found in base Corvettes and Cadillac Escalades, respectively-than the LS7. To enhance block rigidity, GM passed on the LS7's 4.125-inch bore dimensions for the thicker cylinder walls afforded by smaller 4.065-inch holes. Furthermore, the block is cast from 319-T7 aluminum and features larger bulkheads, which makes it substantially stronger than prior LS units. It encases a steel crank, titanium rods, and forged 9.1:1 pistons. With a remarkably efficient 2.3L Eaton blower huffing out 10.5 psi through a dual-core intercooler, the exotic race-ported 12-degree LS7 cylinder heads were deemed unnecessary. Instead, GM opted for 15-degree rectangle-port castings that are very similar in design to the L92 and LS3 heads, but built from more durable A-356T6 aluminum. Sometime this summer, GM Performance Parts will start selling complete LS9 crate motors (PN: 19201990) for about $22,000. Granted that isn't cheap, it's still a heck of a lot less than trying to replicate a motor of this caliber that's also emissions legal and capable of lasting 100,000 miles. Moreover, the rugged LS9 block will certainly be a popular foundation for LS stroker buildups once it's released.
Think of the LSA as the LS9's detuned little brother. Even so, the LSA's 556 hp and 551 lb-ft have helped make the '09 Cadillac CTS-V the quickest four-door sedan to ever lap Germany's famed Nurburgring road course. Major differences between it and the LS9 are the use of hypereutectic pistons instead of forged slugs, and powdered metal connecting rods instead of titanium units. While the LSA also utilizes an Eaton blower, it's slightly smaller at 1.9L, and produces 1.5 fewer psi of boost. It's a very impressive setup, indeed, but the limited production numbers of Cadillac's top dog means there will be very few LSA's to extract from your local boneyard.

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
