Product Details

The March Performance 20450 is a high water flow outward mount serpentine drive kit engineered specifically for small block Chevy engines with short water pumps. This complete conversion system is designed for single-carbureted engines where high-mounted alternator and A/C placement is required.

Premium Construction:

  • Precision CNC-machined from solid billet 6061-T6 aluminum for superior strength and perfect fit
  • Clear powdercoated finish eliminates polishing in hard-to-reach areas
  • High tensile strength construction prevents fracturing unlike common cast pulleys
  • Hard-coated high wear surfaces for extended pulley life

Complete Kit Includes:

  • Crankshaft pulley with 6-rib serpentine design
  • Water pump pulley and nose cover
  • Alternator pulley with fan and cover
  • Outward mount alternator bracket
  • Tension relocation arm
  • Stainless steel tensioning rods with chrome moly rod ends
  • Grade 8 mounting hardware for secure installation
  • 54.8-inch serpentine belt

Performance Benefits:

The street rod ratio design increases water flow and fan speed, providing enhanced cooling performance during critical low-speed driving conditions. This system bolts directly onto 1969 or later small block Chevy cylinder heads for straightforward installation. Note: Will not fit Chevrolet A-body models.

Backed by March Performance's lifetime warranty and manufactured in the USA with over 25 years of engineering expertise.

Placing my order was quick and easy. Thanks!

I did a search with the part number and decided to give your company a try.

Good fast shipping. Easy ordering.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

Wow Super fast shipping, right product, no hassle no fuss. just how i like it. good job autoplicity keep it up.
