What kind of harmonic damper / balance do I need for my small block Ford engine?
All of our small block Ford kits require the four bolt damper used from 1971 and up, on the 302 and the 351, and 1980 and up on the 5.0 liter. Some Ford Racing Performance Parts dampers have both a three and four bolt pattern. These dampers can be used but will require the use of a spacer, either FRPP# M-8510-B351 or FRPP# M-8510-C351.
