and the STOCK rule that the crankshaft has to be "stock OEM" for the engine claimed, and "Crossbreeding parts prohibited.", then a 305 crank being massaged for a 350 application is blatantly illegal in stock. S/S, fine, but not in stock. Will he get caught? Almost certainly not. Are there a jillion other stocker engines out there with illegal cranks? Almost certainly. Does it make it right, absolutely not.

I have been reading this thread and you are dead on the dial with a ZERO!
