Powermaster 82013 Details

If you like traditional looks and reliable, modern performance, you’ll love this cool Flathead "Shorty" 1-wire alternator. It has the look of an original generator, but is really a 12-volt, negative-ground alternator that produces 65 amps at idle and 75 amps going down the road. This model is designed to fit 1939-1948 Ford & Mercury Cars and Ford Trucks with Flathead V8s and features a simple one-wire hookup.

We offer this one wire alternator in a black powder coat finish with included stock-appearing mounting brackets (the stock fan carrier bolts to that bracket) and pulleys that accept wide 5/8” belts.

1.5" shorter than standard generator
Easy one-wire hookup
65 amp idle, 75 amp cruise, 90 amp top end
5/8" wide belt pulley included
If using 3/8" wide belt, order pulley # 910-67178
Uses stock-appearing bracket and fan carrier bolts
Multiple carb apps, (1) 4 barrel carb

What the length of the unit? Do you measure from the pulley bolt to the rear housing, or? I'm running high-rise w/ dual 97 carbs and want to make sure the rear of the unit does not run into the front carb float bowl.
