Horsepower = Torque X RPM divided by 5252

The basic idea was to pick a gear that let the engine develop its maximum horsepower and keep the engine turning in that RPM range more or less constantly. Then the only consideration would be whether the gear we selected would get us there on schedule without too many speeding tickets.

Bigger, higher-torque engines just allowed lower RPM and/or fewer shifts. The little 283 with a 3" stroke and virtually no low-end torque needed a LOT of gears!
