is there a head and cam package that will get close to 500 rwhp with a stock fuel system and ls6 intake on my setup?

 

Stock fuel system including pump and injectors?

 

No theres not. Not with the LS6 intake, and at those power levels you will need new injectors and a fuel pump.

 

You need injectors, pump, and on the safe side the "hotwire" kit that comes with most, if not all pumps. Most guys run into issues pushing low to mid 400's even with all the dyno tuning in the world.

Rails are fine and no FPR needed.

 

a fast 92mm intake will work with a stock fuel rail .read all the 500hp threads .what engine do you want to build ?contact Geoff at EPS .

 

On a stalled automatic you're going to need some *killer* heads, cam and intake to even get close to 500 at the wheels. Not gonna happen on the ls6 intake and will certainly require some sort of fueling mods with injectors at the minimum and probably a fuel pump also.
