I'm curious what your feedback would be concerning the driveline for my truck. What I currently have is a 1966 Chevy c10 with a 250 6 cylinder and a 3 speed on the column. The rear end has 3:73 to 1 gears. I'm looking to lower the RPM's at cruising speed, but still be able to haul a modest load from time to time.

I purchased a 3:08 to 1 rear end that came out of a 1965 Chevy pickup from an ad on this website. Then I purchased a used TH-350 from a member of my truck club. The plan was to swap these in to ease the RPM's at crusing speed.

The problem is that I have been told by some that this would not be a very good setup.

I have considered swapping for either a T-5 transmission or one of the AP N833 4 speed overdrives and keep the 3:73 rearend. Another option is to swap in the 3:08 rearend and get a Sagnaw or Muncie 4 speed transmission.

What do you all think? Pros or cons?

Thanks!
