77 is tops for my '55 1st GMC.

Since we call any GM truck up through '72 a Stovebolt here, I once had my long gone '70 Blazer running down the highway at about 100. Mildly modified 350 with 3.08 gears. Going downhill.

I sold that one more than 25 years ago...

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