To balance are not to balance

Every engine made by Chrysler will improve performance if it's properly balanced. Aside from shaking the parts to peices, there is a certain amount of power taken up by having to work thru bad harmonics. Cranks flex, pistons get hammered, bolts loosen up. It can be a mess. If you dont have positive proof an engine assembly has either been internally balanced, or is a totally original matched rotating assembly, then it should be balanced. Not everyone does it. But IMO, it's a step that every engine should have. My feeling is the people that dont can put up with more "stuff" than I can in regard to performance. And I can tell by sitting in a running car if the engine was or if it was messed up or not done at all.
