Fastest auto trans for SB chevy stocker

One thing about the Pro Trans is the all the gear ratios offered. Metrics not so much. The metric 200 is very close. If you go with a metric, Remac, or Sepanek is my choice. Obviously McClay is a top choice as well.

I have one from Remac in my Firebird, and it has 200 runs on it since the original build. It is overdue for a freshen up. It will go to Sepanek for that

I had over 300 runs on mine before
It was taken apart. Scott has tons of
gear ratios, check his web sight. And
no not a big block but a pretty healthy
Lt1 that routinely goes 1.35-1.38 60'
@ 3400lbs!!

Hey Glenn. I don't have a number. Never owned one or drove a car where we ran them back to back. I've always ran a metric
