This would put the F-P motor with gearbox at around 41.5 ft/lbs. Unless I'm crazy. . .
Nope, that would be the stall torque of the motor/gearbox assembly. You don't really want to stall the Fisher-Price motor however, it will quickly go up in smoke.

In FRC applications, half of stall torque is usually a good number to design around. You can use the sheet here to figure out how fast the motor spins at that torque.
