Ls1 5.7 build advice welcome
The block needs bored what would be the piston of recommendation?
I have c5 231 heads I believe. What would the price difference be in sending and having them ported vs buying other heads and having them ported or buying aftermarket heads already ported.
Would a carbureator or the efi be better to achieve my goal power wise. I need an intake anyway
Thanks in advance and I'm sure I'll have more questions
I think you mean 241 heads, which could use some improvement. I would swap to 243 or 799 heads at the least. You can probably find a pair of them for $350 or so shipped. Porting is up to you, as is carb or EFI. Either will do.
