Hey Lee- one more question that i had was have you had your rotating assemby dynamically balanced in a 292? and if so...did you get a balance card that showed how far off the stock setup was? Do you know what GM's tolerances were for the 292cranks and pistons in terms of weights/grams/etc? It seems like having a dymamic balancing would be the best $150 anyone could spend on the rotating assembly if you wanting to take these into the higher rpm ranges.
