I'm glad you told me the thing about the springs. I thought about getting heads instead of replacing springs, push rods, cam, lifters, etc etc but not sure. As for the gearing, it's got 3.55 gears, 14" wheels with 65 series tires I believe but will be putting 17 inches with a tall tire to help with highway speed RPM's and a TH350 transmission (later I will most likely add a 700r4).
I think what I will do is slowly build this engine and just use the 327 I have in the car now but that cam most likely needs to be changed because it has such a big lope and runs badly no matter how I tune it. I've had a few friends look at it and adjust it and they said it sounds like too big of a cam as well...
