First introduced in the '01 Corvette Z06, the Gen III LS6 is basically a hopped up version of the LS1. In fact, it shares much more in common with the LS1 than the LS2, LS3, or LS4. Compared to the LS1, the LS6 boasts improved cylinders heads, a larger camshaft, a better-flowing intake manifold, a more durable valvetrain, a bump in compression, and stronger main bearing bulkheads. Furthermore, the LS6 head design features a raised port floor, and a smoother transition at the short-turn radius for improved flow. The exhaust ports were also altered from an oval to a D-shaped design. These mods bumped hp to 385 in '01, and to 405 in '02 thanks to an even larger cam. There was a time when factory LS6 heads were the hot ticket for enthusiasts, but the design has long been superseded by superior factory and aftermarket offerings.
Granted it falls 133 hp shy of the LS9's staggering output-which is substantial in anyone's book-but in many respects the 505hp LS7 is an even more impressive engineering feat. Without the assistance of a factory-installed blower, the Gen IV LS7 gets the job done the old-fashioned way, with lots of cubic inches and airflow. Its design was heavily influenced by the Le Mans-winning factory Corvette racing program, and as such, the LS7 packs loads of bonafide race-bred hardware. To achieve its epic 427 ci of displacement, the LS7 incorporates press-fit iron cylinder liners in lieu of the cast-in sleeves found in lesser Gen III/IV small-blocks, which enables boring the block out to 4.125 inches. The short-block is further fortified with a 4.000-inch forged steel 4140 crank, titanium rods, 11:1 hypereutectic pistons, and doweled steel main caps. With nearly 0.600 inches of lift, the 211/230 @ 0.050 cam is just epic, and the dry sump oil system is simply unheard of for a production motor. Displacement is just half of the battle, and the LS7's cylinder heads are equally impressive. These revolutionary CNC-ported 12-degree castings feature 2.20/1.61-inch valves (the intakes are titanium), and flow an astounding 370 cfm. That's enough to put most big-block heads to shame. Best of all, these castings are available from GMPP for about $2,500. The end product of all this pimp hardware is a motor that revs freely to 7,000 rpm and spits out 505 hp, which makes it the baddest naturally aspirated small-block ever built.
All you do is pop it off, lol.

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
