Works pretty good a little soft under 2000 rpm. The gears is my main problem 2.94 with a 2800 stall. Plan on swapping to an airgap and Rhoads roller lifters to help bottom end. Plus add 3.55 - 4.36 not sure yet. See how thr intake and lifters help first.
Do the gears and converter first. You’ll be much happier. Intake later, from r the icing on top .
