Quite simply, I wouldn't do a thing. I'd go run the car, get a timeslip, then, the incrementals on that slip, will tell you everything you want/need to know. You can then adjust with data. This is the old ask 100 people, and you'll get 130 answers.I am sure you will need to make changes, but I wouldn't just guess.
I agree 100%. I personally don't see the need for more converter or more gear. It's a bracket car, no sense in killing the motor with rpm that you don't have to. I am sure it will run quite well.
