V6 Cam?

[GMCrazy777]

i have an 07 sierra classic with the 4.3 v6 and was wondering if there was a cam made for my truck and if i would benefit anything from it. and if there was it would definitly void the warranty wright?

It'll pretty much void the warranty on the entire drivetrain, fuel system, and anything else that touches the engine I'd imagine.

 

 

I'm sure you could find a cam shop that'll grind you one though.

There are some in existance, though not many. Look at Jeg's, Summit racing, or go straight to manufacturers like Crane, Comp, etc.
