Use the following chart to select the proper crankshaft pulley spacer to use with Ford Performance M-6316-C351
crank dampers to achieve proper belt alignment on late model 302 and 351 Windsor engines:
Note: Early 3-bolt crank pulleys generally bolt directly to the damper with flanged pulley pilot (damper is drilled for 3- and 4-bolt patterns). Pulley alignment should be checked and any misalignment corrected with the proper thickness spacer.
