DAVE, I think it depends on the torque output and weight of the car. Back when I ran a small block I had 5.14 to 5.43's

I switched to 4.86's when I started running a big block and lately that is still too much gear.

Excessive RPM at the finish line, violent launches can equate to over gearing.

I know a guy who runs a sbc and has 6.00 gears... that's as tall as I've seen.

My car needs a "soft" hit at the launch.
