The factory Ford serpentine beltdrive has been with us so long that it is hard to understand why any of us would bother with an old V-beltdrive. However, if you're driving a vintage Ford, chances are good you still have the old standby rubber band drive with all of its quirks and malfunctions. V-belt systems tend to eat up belts with great regularity, especially if you're spinning your small-block to the moon. There are accessory alignment and belt sizing issues as well to contend with.
If you're considering stepping up to a serpentine beltdrive, you have options, including copping a system from a late-model 5.0L/5.8L small-block. However, that isn't going to look as sharp as a polished or brushed-finish billet serpentine beltdrive system, and one that has been well thought out and engineered to fit a small-block Ford with a compact demeanor where everything fits snugly in front of the cylinder heads.
Eddie Motorsports spent a lot of time developing its new S.Drive serpentine beltdrive system for the small-block Ford, fitting it with easy-to-find, off-the-shelf components like a Sanden air conditioning compressor, Powermaster 105-amp alternator, Maval power steering pump, and Ford Racing water pump. When you install the S.Drive system, it becomes an integral part of your engine because the foundation for the S.Drive is a cool billet timing cover on which everything is installed. Because the S.Drive doesn't have a mechanical fuel pump provision, you will need to install an electric fuel pump.
You might be inclined to ask what the gain is from the S.Drive. Attributes include durability and good looks. You also get 105-amp, single-wire charging system reliability and the reduced drag of a Sanden rotary compressor. Serpentine beltdrives are buttery smooth and quiet too.
