CHEVY BIG BLOCK SERPENTINE CONVERSIONS

Outward Mount Alternator, A/C and Optional Power Steering

Our performance serpentine kits replace your low performance V-belts, pulleys and brackets while retaining your standard rotation water pump. Simple to bolt on! Eliminates belt throwing. Kits are available with performance pulleys for increase horsepower (approx. 12 h.p.) or high water flow ratios for increased cooling. CNC machined from solid billet 6061-T6 aluminum. This translates into a spectacular looking new machine finish with perfect fit and extra high strength. All our billet pulleys and brackets have a “No Polishing” maintenance-free clear powdercoating. Our kit comes complete with stainless steel tensioning rod, chrome moly rod ends and necessary grade 8 mounting hardware.

Application:

Kits fit most 1955 and newer Chevys Corvettes from 1968-1982. If your Corvette has air conditioning, you will have to use short valve covers with shorter adjusting rod. Contact our technical department for more details on Corvettes. Water pump with nose cover extends forward 6.5" from front of engine block, plus clearance for mechanical or electric fan. *Most applications with power steering will require remote reservoir style pump.
