I think rons goal with the motor and trans was to be able to enjoy the car again and not have to fuck with it all the time. A blower or turbo would work against that. I say the thing is perfect the way it is may be a small cam (sub 228@.050) and enjoy and may be a bear brake kit or some thing like a 91-95 b body spindle upgrade with the 12 inch brakes to keep up with that kick as pro touring look.
