Thanks Denny and I agree because all I was hoping for was around 280+HP.
But I am contemplating doing more to the top-end of the motor next year,different cam and heads and may wish I had got more compression while I had it tore down.But you may have a point there because it's going in a little s10 truck and with the right converter, gears and traction may be as quick as I'd like.280+ HP shouldn't be asking to much from a .060 over 283?
