Thanks to all. Your input is well received and will take all in mind when I actually do the upgrade. Sorry for the late and untimely response but worked nights and had to sleep sometime. Thanks, John L. 70 SS454 ACES #5597

Was sad, the trans only had 200 miles on it.

I've got a '70 SS396 with a 700R4 that works GREAT! I am also building a '70 vert with a ZZ502. For this project, we were originally going to go with a 700R4, but found that the 700R4 tops out at around 450 ft-lbs of torque. My understanding is that the weak link is the Aluminum input shaft. We decided to switch gears (no pun intended) and went with the TH400/GV setup. However one final note....There are companies that are addressing the 700R4 limitations. Bow Tie Overdrives in SoCal has a modified 700R4 that will handle up to 600HP. I've already headed down the TH400/GV path, but it might be worth looking into what you can get from a 700R4 these days.
