Wow, twin turbo hemi! Geeezus. I would like to pit that thing up against mine when I get it done, it's a 360 stroked to 408" with a D1-SC supercharger, Alter-k, same brake kits ( Willwoods front and rear), hydroboost, Strange S-60, alot of the same ideas. I told Dave Hughes and the SCS.com guys I wanted to hit 700hp. I'm kinda building it as a dragon slayer. The Ford 4.sicks , 5.slo , and GM's LS-X's were my target but I could partake in some genocide.
But, really, the twin turbo Hemi would probably stomp my supercharged LA. Plus it has a better straightline rear suspension.
