Product Description

March Performance Performance Series Serpentine Pulley Conversion Kit to Fit Mustangs with 302/351W/C Engines.

March Performance's Performance Series serpentine pulley set replaces your low performance V-belt pulleys while retaining your standard rotation water pump. Designed for normal street driving and simple to bolt on, this pulley set increases horsepower 12.5-15 h.p. at the rear wheels by reducing accessory drag. CNC machined from solid billet 6061-T6 aluminum for extra strength and wear resistance, these pulleys will run perfectly true, eliminating thrown belts. Finished with a "No Polishing" clear powder-coat.

Pulley Specifications:
Crank Pulley - 6 rib; 4-3/8" dia.
Water Pump Pulley - 6 rib; 5-1/2" dia.
Alternator Pulley - 6 rib; 2-1/2" dia. (includes nose cover)

System Requirements:
- Factory 4 bolt dampener only
- Standard rotation water pump
- Driver side lower radiator hose

*Dampener face to water pump flange face is 3-1/4"; Cannot use power steering or A/C."

Product Questions

could you explain to me how to measure the Dampener face to water pump flange face is 3-1/4"; As long as the measurements align up will this fit any 351w

Asked by: Cougar
you can run a straight edge down the water pump flange and use a ruler to measure between the straight edge and the balancer.   this will fit 4 bolt crank 351w engines with the 3.25 inch distance between the dampener and water pump flange.  some early 69 351w engines were 3 bolts for the crank.  if your measure is more than this we also sell some spacers to make everything line up.

What belt goes with this kit thanks

Asked by: Jabronie
The manufacturer doesn't list a belt size, if the original belt doesn't fit you will have to measure for the size.
