This would be my route in the quest for 500hp with what you have on the engine now, IF you don't have hypereutectic pistons, IF you can get an intercooler to fit.
I'm sure there is a way the Dakota R/T people do it. Just googling "Dakota R/T Intercooler" yields some "direct fit" options that I didn't click. From what Engine Masters and Richard Holdener, any cam is a supercharger cam. If it works great NA it will be great boosted. Compression on a closed chamber head with good quench can be higher than the old school thinking of ~8.5:1. In recent years we've been seeing boosted 10:1+ ratios, providing for forged rotating assemblies. You're 114 degree LSA is good. LSA was another thought that was challenged by Engine Masters and Holdener. I still believe LSA's in the upper range (110-114) are better for boosted applications.

I you want to stay N/A then the heads, valvetrain, intake, cam, ... need to get swapped out for what was discussed earlier.

@pat d Either way, we never discussed what your true cam specs, compression, and your rotating assembly is.
