Slap an external balance B&M plate on an engine intended to be internal balanced and see what you get.

You can buy kits that are set up for internal or external balance in most cases. The final balance should be done by a reputable shop.

Exactly, and we didn't even mention the variances in harmonic dampers and torque converters.

I brought everything to the shop, including the harmonic dampner, the correct B&M flexplate for an externaly balanced engine, the Hughes nuetrally balanced torque converter, crank, rods, pistons, pins, spirolocks, rings, etc.
