just out of curiosity, if i got a good set of cams & had it tuned for the new cams & such, how much would it improve the numbers? its an 06' Z with the revup (300 hp, 260 tq)...any idea anyone?

 

Depends on the grind and what you do with the intake/exhaust. This question is better suited for the tech forum.

 

Not worth the money. MAYBE 30 whp with a tune? A set will run you $1K + labor which will be a biotch because you have to tear apart half the engine. Not like a Z06 which would gain like 80whp+ from a cam. So figure $2K ready to roll. Wasnt worth it for me.
