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![]()
