Professional Products Harmonic Balancer, 28 Ounces, Small Block Ford
(Part #91015365-28)
                        

These PowerForce series balancers from Professional Products are available in 28 oz. or 50 oz. balance. They both measure 6.4" in diameter, are 3" in total length, and are marked to 40 degrees at three locations. Plus, they feature both 3 and 4 bolt pulley holes, which allows the use of late model serpentine drive systems on early engines if desired. Counter weight is removable for zero balanced cranks. Fits most 260/289/302/351W/5.0L Ford engines.  6500 RPM max limit.

See Notes tab for spacer requirements.

28 oz. Balancer (S/B Ford V8 1963-80)

  • Matches O.D. and thickness of the stock early (1963-69) dampers
  • Counterbalance weight matches the stock 28 ounce inches
  • Overall balance specifications are held tighter than the original O.E. tolerances
  • Dual Bolt Pattern - both the "early" 3-bolt and the "late" 4-bolt patterns
  • Removeable Counterweight - if building a neutral balance engine simply remove the bolt-in counterweight on the back of the damper

50 oz. Balancer (S/B Ford V8 1981-95)

  • Made to the early short length of 3" - allows the use of a late 5.0L engine with a 50 oz. in. damper to be used in an early chassis where front clearance is at a minimum
  • To fit in late vehicles, use spacers to provide the correct front pulley alignment
  • Dual Bolt Pattern - both the "early" 3-bolt and the "late" 4-bolt patterns
  • Plastic insert shown in photos can be used to center 3-bolt pulleys with a female pilot, or it can be removed to accept 3-bolt pulleys with a male pilot
  • Very versatile and can be used on many different Ford engines
