Thought I'd share a picture of my 65. I swapped in a 2003 4.8 ls based vortec. Also a th400/Dana 20 combo. Trans has a 2800 stall converter and a rv shift kit. It has the closed knuckle Dana 44 front and the 53 rear. I did all if the harness conversion wiring myself. It turned out good. Makes a nice farm truck.if I only had a farm.
