Avalanche

[slammed1972]

I am helping my uncle put a little noise and power in his loud peddle cause his sons 04 gmc short step side rapes his Avy. I was looking at cams and I was wandering if a comp XR273HR would help out a little bit with some nelson tuning and maybe up grade the injectors and ignition system. He has the money and he has told me to do what ever I want so some suggestions would be cool.

If he has the money go forced induction. Check out STS turbo, radix, procharger.

Ya, if he has the funds, an STS would shut that gmc down!
if not, stall, cam, and tune.
It'll be close because these av's are so damn heavy.

good luck,
allen
