NOTE: ¹ With 0.917" Ford Racing crank sprocket.
1979 and earlier 351W with 0.917" Ford Racing crank sprocket can use spacer M-8510-A351 if 0.070" is machined from the rear of the damper hub. Early 3-bolt crank pulleys generally bolt directly to the damper (damper is drilled for 3- and 4-bolt patterns). However, sheave alignment should be checked and the pulley shimmed as necessary to correct any misalignment.
