Yes the trans mount works with everything. A 700R4 is a OD. And it would be nice with a 330 to 373 gear. They sell beefed up versions that will handle a big block. It is the 2nd gear that is weak on stock transmissions. They use a beast sunshell and it solves that.

If you go with a 350 or 400 either will hold up and work. 400 is the stronger. 350 has less parasitic hp loss.

For simplicity, a TH350 would be great. I have run TH350s behind mild 396/402s in the past with no issues.

As far as 700R4s, I am not a fan. The clutch packs in them are tiny. A clutch plate from one will float around inside a clutch plate from a TH350 or TH400 because they are so much smaller in diameter. (Less surface area) Just my $0.02
