LS1-->ls7

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.
