As alot of you know, im running a magnacharger on my 5.3L. Im also running 8.1 injectors. I want to do a cam and heads next, but I need recomendations on what size cam, and heads. What should I use to tune it with? LS1 Edit?

 

The easiest thing to do may be put a set of stock LS1 heads on. Those should lower your compression ratio to just under 9.0:1 which would be good for a supercharger. Also, those heads will give you larger valves stock than the 5.3 heads have.
