There are a few variables. Do you already have a core trans to have rebuilt? Are you going to have it rebuilt basically stock or with the typical upgrades? Do you have a reputable local trans builder?

I put a 700r4 into my 1972 cheyenne super. Works great with 3.42 gears in town and on the interstate.... Easy swap to perform, has been done hundreds of times.
