Description

This 100 Amp, 12V, V-belt alternator from Powermaster features a 3-ear mount and is designed for Small Block Chevrolet (SBC) engines. It is commonly found in kits (e.g., Powermaster 8-7218) with a high-mount bracket for passenger side cylinder head installation, driven off the water pump, avoiding interference with other belt systems. It incorporates an XS Volt voltage regulator, 1-wire wiring, a solid V-belt pulley (1V, 3/8" x 2.80" OD Deep Groove), and a CS121 case.
