Accessory Drive Belt on a Budget

Eliminate The Frustration Of Thrown And Twisted Belts With A Trip To The Boneyard To Build Your Own Budget Belt Drive

Big-Block Serpentine
As good as the small-block system is, we ran across a cool conversion kit that applies these same pieces for a big-block. We introduced you to Kwik Performance with our LS-series engine accessory drive story back in the May '09 issue ("LS Accessory Drive Swap Guide"). The Kwik folks also identified a need for an inexpensive big-block serpentine accessory drive and discovered that with seven simple aluminum brackets, it's possible to adapt the small-block serpentine beltdrive system to a big-block Chevy with kits for standard-deck and tall-deck Rat motors. It's really that simple. For the record, GM did build a big-block serpentine beltdrive system starting in the early '90s through model year 2000 in 3/4 and 1-ton trucks, Suburbans, and other large vehicles. It is possible to find this system, but you're more likely to find it in a truck-only boneyard-and you'll pay more for the privilege. GM Performance Parts also sells a complete serpentine beltdrive system for either standard- or tall-deck Rats with or without A/C.

All the previous parts we detailed for the small-block are used on the big-block with the exception of the water pump. In fact, Chevrolet interchangeability is so good that even the small-block serpentine water pump pulley can be used on the big-block. Kwik's brackets easily adapt the small-block system to the Rat, and the only other critical components you need are a big-block serpentine crank pulley and a different belt. We also found a cool aluminum crank pulley from March Pulleys that is only a few dollars more than the factory steel piece.
