Acura dude, were you there to tear down that vette and make sure its stock with your own eyes? I bet you were, right? Every guy that knows what he is talking about knows the hemi isnt 100% stock, as stated they used what they had and some of it was a little better than stock. Just relax and read up about motors you'll never be able to own or handle so you can try to look smart on the internet. Oh, BTW by time i was 17 i built my roller cammed 408...of course its no fireturd or crapmaro with a 5.7 and headers and a cold air intake.
