One thing to keep in mind. A LT1 with about 7psi makes similar power to a stock LT4 which makes 9-10 psi. The higher compression of the LT1 allows it to make similar power at less boost. The LT4 comes from the factory with a better fuel system. Ideally you will need to run the LT1 a touch richer for cooling on pump 93 due to the increased compression which further increases fuel demand. So that means a 7psi setup really needs the LT4 fuel system hence why I always suggest it as a minimum.
