flow and sound better

Sorry, no sound clips here. Go to a exhaust manufactures page. Comp Cams also has a sound clip on there home page with certain cams.

10.0-1 is seriously pushing the pump gas octane limits unless your cam is ground on a 106 or less or is simply a "BIG" cam. Iron heads should be basicly limited to 9.5-1 while aluminum heads can go one full point higher. This can be argued, but the power gain is really really small. about, give or take 3% per 1 point of compresion. This also can be argued. But it is a good ingeneral area for a street engine.

You also do not need to spend extra (And hefty) for roller rockers. Ethier the MoPar HD Hyd. replacement rockers or Mech. rockers from Crane will be more than enuff.

Don't use the Rhodes lifters for no apparent reason.

I'll recomend a cam once you have figured out what engine your going to use and when I know more about your car. Theres lots of ground to cover here before I would recomend a cam that would work well rather than just work given the lack of info you have given up.

We have really just covered all the give me on this topic so far. Are your ready to get serious or just screw around bench racing dribble?
