The shortblock will come internally balanced. Any neutral balanced flywheel and Pressure Plate can be then fitted to the engine with nothing further to worry about.
I took the FW/PP assembly to a good tyre shop, where they did dynamically balance it an a Hofmann electronic wheel balancing machine.
The weight to be added was exactly the same I had added doing a static balancing,only about 10º off angle. So the static balancing was not that bad and is in any case better than nothing.
FW/PP is now balanced to within 3 gramm.
I will have to weld a metal plate with the correct weight to a lateral of the pressure plate. No way I am going to drill any holes in the PP nor the flywheel, which is aluminum and was neutral when I tested it separately.
My crankshat broke at the front, near the harmonic balancer, and despite that the original Ford balancer is sound, I will order the KC482 shortblock with a new harmonic balancer,, jut to make sure
