It's just as if it were a Fbody or a GTO

steal upgrades from the big brother, not to hard. or swap in a 6.0L truck block. its all the same platform LSX so i don't understand when people say no aftermarket for Ls4, Cam, Heads, Intake, Headers, Juice, and i'm sure you can turbo it am i right? so there is a market, its just NOT as popular that's all. its all the same, I just like my L67 more, 1 it weighs less secondly i like cheap boost lol.

for me to get a ls4 i would have to come up with Atleast 2 grand to get a turbo build started. lsx blocks are easy to come by, but doing the turbo would be the hard part, get a 90-10X intake manifold From FAST, and a throttle body and your set. It's all the same. SO go for it

oh and the trans, Beef her up before you do this lol


And i have the 5.3 in my truck, and with a small cam, headers and intake work she moves pretty damn nicely.
it's not a junk motor, I know of so many people that put them in there v6 camaro and stomp 346 (lS1 5.7) motors

LS1 5.7L (346 cubic inches)
LT1 5.7L (350 cubic inches)
LS4 5.3L (325-327 cubic inches) can't remember

all great motors doesn't even matter the size of the inches, It's how you use it that matters

the ls4 crank is a little over 10 mm shorter than standard ls blocks iirc. the first thing to do is get rid of dod. next get the most displacement you can out of it. you can prolly get a 383 but again the cranks different to its a matter of making a crank as the another ls wont fit. headwork and a cam and youd be pushing way more power. not to mention the sound. im still considering a ls4 swap but itll prolly sit on a stand until its fully done. ive also been told youll need the cradle and suspension from a gxp too. im only lookin for about 300whp so a l67 build would be way easier and cheaper. and the whine is better than any ls4
