Gear Ratios
Posted this on the 4x4 board, but the same philosophy should apply to 2WDs.
I've got a 70 Chevy shortbed, fleetside 4x4. When I had the rear differential rebuilt, I was told I had 373 gears and they were considered "highway gears" I'm running a 2001 ZZ4 Corvette motor from GM, with 33 inch tires......Are these gears too high for this application? The motor never seems to run at its optimum RPMs. Looking for some input, good or bad. Thanks, Bradleyworld |

you probably have 3.07 gears they are highway gears. 3.73's are good go fast gears and with a 33inch tire you would want 4.10's or so
