With the same specs we've been using, the static compression ratio would be 9.89:1
I'd be tempted to use a CompCams XE262H cam. 218*/224* @ 0.050" tappet lift, 0.462"/0.469" theoretical valve lift, 110* lobe separation angle. Makes power 1,300 to 5,600. I'd use a 3.50-3.70 gear and a 1,800-2,200 rpm stall converter and a good set of equal-length headers into 2 1/2" pipes to the back with X or H crossover just behind the collectors and free-flowing mufflers.
Again, call your favorite cam grinder for an exact recommendation.
Other board members may have slightly different advice for you, but I'm just trying to get you close so you can see generally what cam to use with what compression ratio. It's a scientific process. You can't just pick a cam out of mid air because you read some hype about it or your buddy suggested it.
baddbob has asked you twice now to describe your pistons. Without specific information, what I've suggested here is just so much doo-doo.
