[DeTomaso] Harmonic Balancer

[JDeRyke at aol.com]

Second possible problem with balancers: the OEM harmonic balancer had a 28 
inch-ounce imbalance weight built in to help balance the crank, and the OEM 
flywheel did also. Then, to keep us alert, Ford changed the balance factor 
in the early '80s for pushrod small blocks to 50 inch-ounces. So when (not 
if) you order a new harmonic balancer, be very sure you specify a 28 (or 28.2) 
in-oz balance factor- and that you receive what you orderered. Mixing up 
the factors on either balancer or flywheel will make a stock-balanced engine 
shake like a wet dog and the only fix is to change the new part for one done 
right! FWIW- J Deryke
