  • King Chrome GM One Wire Alternator, 65 Amp

    Streamline the engine compartment in your street rod or muscle car by eliminating excess wires with this King Chrome 1-wire alternator. Based on the GM Delco-Remy 10SI alternators, these 65-amp units are perfect for vehicles with few electical accessories. King Chrome alternator housings are hand polished to a high luster prior to applying the show-quality triple chrome finish.

    This one wire alternator simply needs hooked up direct to the main battery lead or power source. Then the internal regulator picks up the available current and kicks the alternator into the charge mode at the pre-set voltage. 

    • Hand polished, triple chrome plated finish
    • Quick, easy hook-up with supplied instructions
    • Internally-regulated GM 10SI style alternator
    • Attaches to all popular GM alternator brackets

                Whether you need a high output alternator to power your muscle car, street rod or touring machine, MSD has you covered with the DynaForce Alternator. For the street, MSD offers a 120 or 160 amp one-wire alternator. Not only are they designed for extreme output at higher rpm, but MSD balances the current output to keep your electronic components up to speed during idle and lower rpm operation as well. Both the 120 and 160 Amp alternators feature one-wire installation to keep things clean, easy and effective. The charge post of the alternators is moved to the side of the housing to allow for improved clearance to the block, plus a pulley baffle is included to ensure there is never any fan-to-belt issues (common at high rpm on lesser alternators). The housings are available in four finishes including a natural cast for stock looks, a show quality chrome, black for subtle appearance and a great new satin finish for a smooth finish.

    Just because you've got a vintage Flathead Ford V8 in your ride doesn't mean you're stuck with the antiquated charging system. Switching to a tried-and-true GM 1-wire alternator is a great upgrade for any Flathead-equipped vehicle with a 12-volt electrical system.

    • Bracket fits 1946-1953 V-8 engines
    • Heavy-duty steel construction
    • Can easily be painted to match your engine
    • Designed to work with the two narrow-belt drive system typical of late '50-'53 Ford/Mercury passenger cars
    • Will not work with single wide belts unless the alternator is modified (see Notes)

    Don’t worry, Speedway has you covered. This alternator pulley allows the use of a 5/8" wide Flathead-style belt on GM externally regulated, SI and one-wire alternators.
