Designed to reduce the horsepower drain and slow the water moving thru the radiator to allow it time to cool its very important for the higher RPMs run today. This oversize pulley is 4.2" diameter, older stock is 3.875". Use of a high capacity water pump helps to reduce cavitation in the water jacket, particularly at high RPM, as well as circulating a greater volume of coolant. Further reduction of cavitation is achieved by using a larger diameter water pump pulley CAM6408 on the A-Plus engines but it is necessary to check clearance between the large pulley and the head; if a lot of material has been machined from the head face it may foul the pulley. This is why this 4.2" alloy pulley has been reintroduced.Originally 4.265" Small bore engines with 12G940 heads can use CAM116 usually but never CAM6408.
