A stock block can handle about 550 HP, unless you use the old spec racer trick and do a Cryo freeze. That, plus a main girdle should keep it safe to about 650 HP. Beyond that the R302 or the new Dart block. Software for "blueprinting" your engine...I am not sure what you mean by that and how that contributes to a gain in HP. For the stock classes running in the NHRA it is a key ingredient (clearances and casting numbers etc.), but for what you are doing it makes no sense at all, since all the clearances you set would definitely not be for running in a stock class. Can you explain?
