I could be wrong, but I don't see the gen 2 hemi dying out. It'll just get more expensive to build a "mild" one b/c you'll end up having to buy a billet block unless someone other than Bulldog and Indy step up. Look at all the fast drag cars...most are running blown/turbo billet hemis. Still a Gen 2 engine for the most part.
