Wow!! Just read your comparison between the 200 4R and 700 and it eased my mind a bit. My 200 is behind a 455 HO, but it has been beefed up and runs great. It has some Art Carr parts like a 300 m input shaft and anchor pin, some billet prices that I can't remember and a much better pump along with a shift kit. I wish that more of these trans where available. The car has 3:42.1 gears and would probably work great with 3:08s.
