Since I am relatively new to this site, and to the larger trucks, I need some advice. I have 1951 GMC 1 1/2 ton with a two speed rear. I love this old truck the way it is, but I was wondering if there would be a way to get her up to maybe around 65 or more? I have no idea what kind of tranny would be a good idea to use or if this is even possible. I want to keep the original engine, the 270 because I know they hardly ever die. Can someone offer some help? Thanks!
