I put an o'd trans in a 1954 Chevy pickup, it was fantastic! It would cruise at 75 M.P.H. at 2000 R.P.M. the stock 235 never even strained. I installed it with one wire from a switch to the solenoid. It would go into o'd at a dead stop and worked smoothly. The trans was a direct bolt in, absolutely no problems, total installation time including wiring was 1 1/2 hrs. Do it, you will love it for sure.
