Ali, you'll never get through to Yuck and some of the others. Progress is good.
The architecture in the new hemi is light years ahead of the old wedges that were based on 50s era technology.
The only thing the new engines lack is displacement. There is simply NO WAY an old 360 will make the same power as a 5.7 without giving up street manners and efficiency.
The 6.1 will make more power than a similarly equipped 440.
It's easy to make stupid power out of a 440. The same things can be done to the 6.1 to make it just as strong. It takes a pair of big money wedge heads to match the flow of the stock 6.1 heads. Add a little work to the new stuff and you'll be chasing B1 or big Indy heads to keep up.

Doesn't anybody rememebr the Jeep SRT running 9s with a full interior?

The new engine is a little pricier than the wedges. It's a little more difficult to swap at the moment too. However, those swaps are getting easier as more people get on board.
