I am replacing the engine in my car and I am going to a setup with a ls7 topend. I guess I will run the factory fuel rails,as I have not found any alternatives.

Here are my questions:

1. Will they be enough?. ~600 rwhp
2. Does anyone make a fuel injector (50-60 lb) in the stock height(LS7)? With the ls7 style connector?

 

Use the factory LS7 injectors along with the adapters from Caspers electronics.

 

If I am not mistaken, the factory injectors will not be enough for my needs. They are 40 lbs

 

What do you mean by LS7 top-end? If I'm understanding you correctly, that means LS7 heads, intake, and exhaust manifolds. What are you putting this on? LS1, LS2, LS7 block??

If the block doesn't have at least 4.125" bores, the heads are too big. Need a 427 or bigger.

I could be wrong, but that's the way I understood LS7 components.

 

wait if i wanted to run ls7 heads in my 02 camaro id need to run different headers? i have kooks LTs on my stock ls1 heads now....and yes i know id need a 4.125 bore

 

See sig. the smallest bore is a 4.10. Mine is a 4.11 Resleeved LS1 block.

LS7 heads and intake.

 

so ls1 block + ls7 heads/intake = what kind of power? and whats the deal with the ls7 exhaust manifold? why would that matter?

 

You can't run LS7 heads on an LS1 block. Re-read this thread.
