Sometimes finding a matching set of V-belt pulleys and brackets for a big-block can be a bit difficult. Fortunately, the aftermarket has toed the line and offers kits for all the front drive accessories. Eddie Motorsports has recently introduced a new line of S.drive billet aluminum serpentine pulley systems for the Rat engines. This puts modern-day efficiency of a serpentine system on an old-school engine, freeing up a few ponies and eliminating the possibility of throwing a belt. The American-made, compact S.Drive system features pulleys and mounting brackets that are CNC-machined from 6061-T6 aluminum and incorporates provisions for an alternator, power steering pump, and air conditioning compressor. Kits are also offered for non-A/C and power steering vehicles if that is what you need.
