I have looked at forums and I have not seen anything about what I want. I am wanting to rebuild a 427TD to use it as a actual towing vehicle. It will be mated up to a 5 speed and a two speed rear ( torque instead of HP is my focus ) Looking to see what others have done or options to do. Bore, stroke, cams, etc looking for ideas and whats out there. I have called local shops and no help.
