I have acquired a LS1 block , 5.3 Aluminum heads, LSX intake, wiring harness, roller rocker assemblies, and many other parts, and would you believe I have $ 0.00 invested up to now, (my son is a mechanic at a chevy dealership). My question is what kind of power can I expect from the 5.3 stock heads? Are should I have ported and Polished? I also would like info on where to get the following for the best price?
Crank
Rods and Pistons
ECU
