I had a 402/700R4 combo in my swb '67 stepper. It worked great. Two years later I decided to change things up a bit and when I disassembled the transmission, I was surprised at the amount of damage. I've since decided that the 700R4/4L60/4L60e doesn't really like the torque of the big block. Long term it's not the best solution.
