If an engine has been built (ie balanced, installed and ran) with regular (stock) stud bolts for the main caps, is it possible to simply remove them and replace with ARP version? Assuming you torque them correctly. Or, would you need to rebalance/change anything else? At what level of performance/HP should ARP be considered? A buddy has a late model 302 built (probably 250-300 hp max) and was concerned with the stock main cap bolts, but he's already got the motor in the vehicle. I don't think it's necessary to change, just curious on other thoughts.
