I actualy have access to a 58 235 sitting in my grandfathers 55 first. If he ever dops a 350 in it like is says he will then I have my 235. The whole truck has to be rewired, needs a bed too because in the 60s somebody converted it to a flat bed, and I need to take it apart for paint. Also if I run this thing with the 235 does anybody know how it will afect my unsynchronized 4 speed. I know everything will bolt up providing I use the original bell housing but I don't have any idea how it will affect my ability to drive the truck.
