Going on the assumption that its an '86 302 with a 50 oz imbalance, it
now has a 50 oz. imbalanced damper. So is the engine now balanced or
does it also need a 50 oz. imbalanced flywheel for a total of 100 oz.
of external balance? Does just the damper need the 50 oz. imbalance
weight or does the flywheel need one too?

Thanks, Dave
