    March Chevy Small Block Deluxe Outward Mount Serpentine Kits replace your low performance V-belts, pulleys, brackets and eliminate any issues with belt throwing. Complete and simple to bolt on. Outward mount kits locate your alternator and A/C outside the engine outline and back towards the cylinder heads, ideal for engine compartments with minimal engine to radiator clearance. The "Deluxe" kits feature the original style mounting brackets that are precision CNC-machined from solid billet 6061-T6 aluminum to fit perfectly as well as handle high torque and vibration.

    The high tensile strength of the material combined with the hard coating on all high wear areas means a much longer duty life than common cast pulleys with no chance of any type of fracturing or structural failure. All pulleys and brackets have a "No Polishing" maintenance-free clear powdercoating. An adjustable stainless steel tensioning rod with chrome-moly rod ends and mounting hardware is also included. There are two pulley ratios available; Performance to increase horsepower by reducing accessory drag, with typical gains of 12-15 horsepower at the rear wheels and High Waterflow to increase cooling by speeding up water flow and fan speed, critical for low speed driving where most overheating occurs.

    Kits Include:
  • Alternator Bracket
  • Alternator Pulley with Fan and Nose Cover
  • Water Pump Pulley with Nose Cover
  • Crankshaft Pulley
  • Idler Bracket with Dual Idlers
  • Heater Hose Extension Fitting
  • Tensioning Rods & Adjustable Rod Ends
  • Grade 8 Mounting Hardware

    Power Steering Kits Add:
  • Power Steering Bracket & Pulley

    A/C Kits Add:
  • A/C Bracket, Hardware and Nose Cover

    Kits Require:
  • Fits most 1955 and newer Chevys and 1963-82 Corvettes
  • Up to 17'' Clearance from water pump centerline to side of engine compartment (see diagram below)
  • Water pump pulley with nose cover extends 6.5'' from engine block, plus you will need to consider clearance for a mechanical or electric cooling fan
  • Will not work with Blower set-ups, idler pulley interferes with blower drive belt
  • Two accessory holes in cylinder head for mounting
  • If using ZZ4 timing cover you will have to modify short water pump for clearance
  • GM 10si style alternator with mounting tabs at 6 and 12 O'Clock
  • Most kits require a standard rotation small block Chevy short water pump
  • Power steering kits require power steering pump style specified, must have side motor mounts on 1955-57 Chevy, must use remote reservoir style on Chevelle, Monte Carlo, El Camino, 1970-up Camaro and S-10
  • A/C kits require a reverse rotation 1984-91 Corvette water pump and Sanden 505 or 508 Compressor
