hey guys, I have a 347 short block I'm looking to complete. I was told by the shop that built the motor that c/r would be = 58cc=9.21:1, 61cc=8.92:1,64cc=8.66;1,68cc=8.33:1. My question is , what would be the ideal c/r, and also what h/c/i would be best suited for this setup. My intent is to just have a nice powerful, streetable car, I'm not looking to drag or anything, just a nice weekender that will kick the $hite out of any import that comes along! I keep forgetting this, it's a '90 drivetrain in a '66 with aod, flowmaster full exhaust,a/c and smog delete, and also, what size injectors do you recommend, 24;s ok?

if you are absolutely, positively sure, that you are NOT going to be using any kind of forced induction(charger,turbo,nitrous), go for 9.5:1

if no forced induction will EVER be used go with a 10.0:1CR. the 9.21CR is fine. ur pistons will chance the CR quite a bit. 8.6CR if you will boost.

whoa there big sig, cut that bad boy down a bit

yea what mattdel said 9.5 if no power adder


and 24# inj's are way to small at the very minimun 30#'s

I was considering either the trick flow street heat, or the holley systemax, just because everything is already matched and I'm not that savvy with this stuff yet, any other combos that would work as well or better are greatly appreciated.

mattdel

for the love of god, don't get trickflow.

holley is better.

mattdel, any specific reason why trickflow is out? have you heard of/ had bad experiences?
