I think your mileage is already fantastic! A 1-ton doing that good is something to celebrate!

I just bought a '50 1-ton frame and running gear from a guy who drove the truck for years, but has recently used the cab on another project.

He had swapped a later 14-bolt Chevy rear under it with 3.70 gears. His comment was that with the stock 216 that rear was just too high.

What motor do you have and what gears are in that Mazda? You might not be too happy with it after the swap.

It's true. I really don't do anything but browse the Internet looking for trouble...
