318 1/8 time improvement

Yeah well that was with no manual shifting so the car was shifting at 5k but when I manually shift it she can hit 6k before she goes flat. The transmisson has a transgo shift kit and stock converter. I believe I’m at total 32 but I would have to check I know for sure I have 18 mechanical that’s how I set the plate. With the light spring.
370 track elevation, and yes I verified I’m getting wot
Just because it will "hit" an RPM, don't mean it will run the best ET there. You'll have to play with shift points. Maybe next time try 5300 and see how it responds. And play from there... Also, play with timing. It may like 34* or 36*, who knows till you try it.
