ford flywheel and harmonic balancer

Keno,
thank you so much for your prompt reply and information. I will check the snout for roundness and I am going to install a new harmonic balancer even though the other one only has 110 hours on it. The snout could have been bent- out of round and never was check by the rebuilder or I could have installed the balancer unevenly. I'll let you all know the results. Thanks again.

In 2016 I bought a 1984 ford marine 5.8 liter winsor engine rebuilt and I used my 1973   28 ounce flywheel and a new 6.53 inch/ 28 oz. 3 bolt harmonic balancer    so I could use my pmc engine 3 bolt pulley. The engine has about 110 hours on it and runs good but i notice when I installed the new Harmonic balancer in 2016 that there was a slight wobble in it. It still has the wobble- about 1/32 inch in movement. My pmc engine is bolted to a shaft connecting a volvo penta sterndrive. I have read 2 different reports. One says that the pmc engines used the 28 0z flywheels and 28 oz balancers up to the late 1980's. The other report says that ford autos changed to a 50 oz flywheel and balancer after 1981. Does anyone know about this? I hate to pull the whole engine and lower unit to change to a 50 oz flywheel and 50 oz balancer. I am going to remove the harmonic balancer and check the crankshaft end -snout - with a dial indicator to see if its out of round
your thoughts and suggestions please
