All Chevy V6/V8 engines with a one-piece rear seal are internally balanced. Many people think the engine is externally balanced because the flex plate used on those engines has a counter weight. The counter weight was placed on the flex plate in order to compensate for the lack of a counter weight on the one-piece seal rear main flange. You must use a counter-weighted flex plate on crankshafts having a one-piece rear seal because the crankshaft flange bolt pattern is different from the flex -plates that do not have a counter-weight. That feature keeps people from using the wrong flex-plate.
