Default Re: 1947 starter torque

My old MOtor Manual lists the 1938-48 as 100 RPM cranking speed, 14 lb of torque, 550 load amps, 45-60 spin amps. I am surprised at the low torque, but then the gear ratio to the flywheel is a substantial multiplier.
To tie this into this forum, I would guess that the model A starter is not much different because there is some interchange on the parts. My mix and match 12 v conversion has a 56 field coils, Model A end plates and flathead armature. Others may have more info.
