Details

If you like traditional looks and reliable, modern performance, you’ll love this cool Flathead alternator. It has the look of an original generator, but is really a 6-volt, positive-ground alternator that produces 50 amps at idle and 55 amps going down the road. This 1-wire alternator is designed to fit 1949-1953 Ford & Mercury Cars and 1948-1953 Ford Trucks with Flathead V8s and features a simple one-wire hookup.

We offer it in black painted or polished aluminum, and both include stock-appearing mounting brackets (the stock fan carrier bolts to that bracket) and pulleys that accept wide 5/8” belts.

  • Easy one-wire hookup
  • 6-volt positive ground
  • 50 amp idle, 55 amp cruise, 60 amp top end
  • 5/8" wide belt pulley included
  • If using 3/8" wide belt, order pulley # 91067178
  • Uses stock-appearing bracket and fan carrier bolts

  

Application

  • Case can be shortened for additional clearance
  • Case diameter is 1/4" larger than a stock generator

Overall Assessment

Customers appreciate the product's authenticity, ease of installation, and the improved performance it offers. Many stress that it matches perfectly with their original generator and enhances the vehicle's functionality by effectively charging the battery even at low rpm's, leading to brighter lights and possibly better sparks. The solid construction and period-correct design are also frequently praised. However, some customers suggest the ability to select the correct pulley size upon order would enhance convenience. The product stands as a highly recommended and beneficial upgrade over stock generators.
