This CVF Racing 1-wire alternator puts out an advertised 140 amps in a Ford 1G/2G-style case for classic Ford builds. It runs on 12V DC with an internal regulator, so it needs only a single charge wire, and CVF says it is engineered for strong charging at low RPM.
It comes with a steel alternator fan and steel V-belt pulley and has a stealth black finish. CVF notes this alternator is imported and not made in the USA, and it is covered by the CVF Racing Lifetime Warranty.
