Just bought a 1/2 ton 1946 Chev pickup at a garage sale this morning, and I am excited. I haven't got it home yet and didn't have a camera with me, so no pictures till I get it home. It is all stock and is suppose to run. I know these old Chev's don't have a very high top speed. Is there an easy way to fix that? Change the rear end or something, I don't think they ever made an overdrive for them did they? I assume it has a torque tube rear end, but it was pouring rain when I looked at it so I didn't crawl under it to look. Any suggestions as to how to make this hiway drivable, without changing the entire drive train would be appreciated.
