Re: swapping transmissions while swapping motors???

Since you're going to be redoing the truck, see if you can locate a friendlier rear axle like a 3.08. Along with a OD automatic like a 700R4 it would be easier on the mpg. On my 69 I removed the 250 three on the column and went with a 350/TH350 from a 77 impala and rear end from a parts truck. It helped on the highway and improved gas mileage a little.

The problem for you is finding the parts. Back in the early 80's there were still quite a few 67-72 chevy trucks in salvage yards. If you can find a parts truck that would be your best bet.
