cam choice

First of all I would be more concerened about performance than sound.

Having said that I would go with a XE256H or XE262H.

These shold put you right in the good performance, good sound catagory. Especially with your headers and free flowing mufflers.

Need a little more information on your set-up gear,stall,etc.

Call Comp Cams,give them all your info. See what they say. Bet I'm very close.

Similar, but slightly better cams are the Lunati Voodoo 256/262 and 262/268. I'd recommend the former, which is what I'm also putting in my '70 Duster 318. It's also got the 7-1/4" rear with 2.76 gears, so the extra low-end should help out a bit. If I was going with deeper gears and some extra head porting/compression I'd probably go with the 262/268.
