Good information on the link Joe H! I am getting ready to put a 700r4 behind a 350 with a 3.08 rear axle, just like your link talked about.
I one time considered using a TH350 until I looked up the 1st and 2nd gear ratio differences between a TH350 and a 700r4 online.
Always nice to get confirmation from multiple sources.
