That sounds like its going to be a fun engine.

FYI, balancing an engine is easier and less costly if the new bobweight is less than the old bobweight. It is much easier to remove mass from the counterweights than it to add. As most of the aftermarket stuff for Mopars weighs less than stock, it'd take real determination to increase the bobweight. Case in point: Molnar 360 rods weigh 623 grams. Stock 360 rods casting number 645 weigh 758 grams. Even the skinny shank 318 rods weigh over 720 grams.
