  1. Fuel Pump Eccentric Applications: This gear is for use with one piece fuel pump eccentric (Ford part number C3AZ-6287-B) generally found in engines manufactured prior to 1975. However, the 2 piece style eccentric can be bolted up. The two piece style is functional and will work if there is sufficient clearance to the front cover. Check the cover clearance for 2 piece eccentric use.
  2. This set is equipped with a 3 keyway crank gear to provide standard factory timing, 2 degrees camshaft advance, and 2 degrees camshaft retard. Aligning "0", "A", & "R" mark on crank gear with the "0" mark on cam gear provides these 3 valve timing options.
Some parts are not legal for use in California or other states with similar laws/regulations
