How good is the new Hemi, REALLY?

you need to pickup the latest issue of engine master,,winter 2007 issue.
they put a paxton on a 5.7" hemi and make 720 hp with only 10 psi boost on the stock bottom as delivered from the factory..
They do admit thats pushing for factory pistons though,,i think times going to prove it to be a great engine but your right on thin cylinder walls that they engineer into all new engine,,that will be the ultimate limit,,,,
