I have been trying to decide what the best automatic trans for my 54 chevy 5 window pickup would be. I have a diff from a 2003 S-blazer 4x4, 2.73 gears and I want to use the stock 235 engine. I have been told that the 700r4 tranny is a good choice, but I then read it would be a dog. Any other ideas? I am so confused.
