Default Re: 1947 starter torque

The starter drive to ring gear ratio is very close to 15:1. If you put a torque wrench on the front crank bolt and it turns over with less than 150 ft-lbs then a starter that gives more than 10 ft-lbs of stall torque will turn it. If 150 ft-lbs doesn't budge the crank forget the starter, fix the motor!
