GM motor sport have the cam package on sale, for a cam in an L77 it going to cost $4100 that includes dod delete, not sure on how much extra the heads are to be done. I will NOT be doing any boost in the seeable future. Is it worth doing the heads to get a little extra power? How much more fuel would a stealth cam use? Its a very small cam but worth knowing as ive heard people say don't get a cam due to the increase cost of fuel. How much louder is the car with the cam? Currently have full 3inch with rex headers and cats and mild steel catback xforce. Might make the drive to GM motor sport today and see it all for myself. 2hour drive from were I live. Thanks, PS. if you mention another make of car in this post, save yourself the hassle and get off the JUST COMMODORE forums.
