I'd think this recipe would get it easy enough:

CR: 10.5:1 (since you're using AL heads, should be fine)
Heads: Prepped eddy heads from any of the mopar specific shops (I got mine from hughes, great results)
Cam: Comp XE/Voodoo/Huges/Racer Brown/etc...anyone with aggressive lobes and specing ~ 232-238 @ .050 on the intake side w/ 108-ish LSA
Headers: You'd want at least 1 3/4, but there are so many 1 7/8th's out there that are good quality...
Any of the "good" ignition systems.
Personally, I'd go with a good loose converter (2800rpm) and a mechanical secondary 850HP carb...

That would be an easy 500 hp, with reasonable streetability and killer performance.
