This CVF Racing water pump pulley is a 2 groove V-belt design machined from billet aluminum and finished in stealth black, built for Ford 385 series big block 429 and 460 engines. It measures 5.2 in across and mounts with a 4 bolt pattern on a 1.75 in bolt circle, with a pilot that accepts 5/8 in and 3/4 in water pump hubs.
CVF labels this pulley a high flow ratio design. At 5.2 in it is smaller than CVF's standard 2 groove big block Ford water pump pulley, so the pump turns faster relative to the crank.
