cost of balancing a motor?
TSP quoted me 225 flat.
Local guy that does a lot of pro stock engine building and blown alcohol stuff quoted me 200 + mallory if needed to balance to NASCAR specs.
Another local quoted 180 + mallory if needed, he's prolly more budget minded.
I'll prolly go with the pro stock dood.

i paid $210 for mine to be balanced and the crank polished, from Tony Barker in MS.
Mallory metal, also referred to as heavy metal, is approximately 2.33 times heavier than steel. It is used to add mass to the counterweights of the crank to allow the crank to be properly internally balanced. It is used in the place of lead because it is much less labor intensive, however the cost of the material is exceedingly higher. Typically, no more than about $50-100 worth of mallory needs to be used.

In simplest terms, think of having your tires balanced. It's round and it spins. If it isn't balanced, you'll have vibrations. Now multiply the rpm that unbalanced tire sees to meet the revolutions a motor see's, and you'll probablly shread the tire from the rim.
No, I already know about all the balancing stuff. I thought you guys were getting them balanced more true than what the factory might have given you. For example, my spec stage 3 came balanced from the factory but it still wasnt zeroed out because the balancing machine told us otherwise.
