Can stock rod and stock crankshaft handle the power?

There is a member here with a username Spareparts. He has run nitrous very successfully and I know exactly what his E.T. is, though he has asked me not to share, I can tell you it is very, very impressive with a 318 in a well over 3k lbs duster street car. He races for money, that is why he doesn't share the E.T. I can tell you, he has taken out well set up Fox bodies on boost. No, the 318 wasn't a stroker, Jpar :D
