Many consider the 5.7L LS1 as "the new 350 Chevy," but that title more accurately goes to the 5.3L Vortec truck motor. As the bread-and-butter small-block from '99 onwards, GM installs the 5.3L in the vast majority of its fullsize trucks and SUVs. Considering that GM has built way more trucks than cars in the last 10 years, the 5.3L is far more plentiful and cheaper than its 5.7-, 6.0-, 6.2-, and 7.0L big brothers. For roughly $500 at your local boneyard, complete 5.3L motors can be had for a fraction of the price of an LS1 or an LS6. Price alone, however, isn't what makes the 5.3L the biggest sleeper in the Gen III/IV camp. Its cylinder heads flow just as well in ported trim as 5.7L LS1 castings. In fact, in the early days of Gen III tweaking, before aftermarket heads became widely available, many enthusiasts preferred 5.3L heads to 5.7L LS1 heads due to the slight bump in compression that their smaller combustion chambers afforded. For those that see the 5.3L's smaller displacement as a drawback, it has sufficient cylinder wall thickness to easily accommodate the same 3.900-inch bore diameter as the 5.7L. The added durability of an iron block is tough to beat as well. From '99-07, GM built several versions of the Gen III Vortec 5300, of which the LM7 is the most common. The LM4 and L33 are aluminum-block variants of the LM7, while the L59 is a flex-fuel spinoff. GM began phasing in Gen IV 5.3Ls in '05 with the launch of the all-aluminum LH6, which replaced the LM4 in midsize SUVs. Then in '07, the iron-block, 320hp LY5 was introduced as an update to the stalwart LM7 for use in fullsize trucks and SUVs. Also that year, the LMG and LC9 were unveiled as flex-fuel versions of the LY5 and LH6, respectively. Finally, the LH8 is a slightly detuned 300hp 5.3L that powers the '09-and-up Chevy Colorado pickup.
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
