Sean,
FWIW,
Although the flywheel balance is referred to as "28 oz" a more correct
description is "28 in-oz." The actual balance weight on the flywheel is much
less than 28 ounces (1.75 pounds) but the actual weight on the flywheel
combined with the distance to the weight from the center of the crankshaft
creates an out-of-balance torque of 28 in-oz.
This flywheel out-of-balance combined and aligned with an equivalent
out-of-balance in the vibration damper compensates for the fact the 351C
crankshaft is built missing one set of counterbalance weights. That is why the
engine is called "external balance."
Have fun today,
SOBill
