I have 3.08 gears behind a GMC 270 with the stock 4-speed.

The truck will easily run past 70, and setup that way. However, pulling an empty trailer I feel the load starting out and trying to accelerate. It does make a big difference.

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