    These torque curves mean so little! 6-71 peak torque was at 1200 rpm. Was there a single driver who wasn't bumping the governor driving one? My truck has a plaque on the dash that lists ideal RPMs for fuel economy, cruising speed and minimum rpm for hard pull. Basically it said "if you're pulling a hill with this green motor, we're going to beat the snot out of you if you let it see 1399 rpm!"
