4 speed/ gears and 60 ft

This has nothing to do with stick cars but I broke my 5.14 gears in my 9 in. ford rear and installed a 3.50 gear out of a Ford truck so I could race and I only lost a tenth in the 1/8 mile and gained 1 mph. I crossed the finish line in 2nd gear. It was like a power glide with over drive for the drive home. But i installed some 4.56's and went faster.
