I haven't chased that dream much. Intake,carb, and some kind of ignition work around?

If we talking NA then no, the Hemi is not the answer unless you like big RPM. NA Hemi’s are pigs. This is not unknown but appears to be a mystery in certain circles.

If anyone is unclear on this look at the flow path of air through an in line wedge, the various canted wedge heads and then the Hemi. It should be obvious when look at the flow path.

I think 600+ hp comes cheaper with a Gen III than you'd get from buying a LA version of a "race block", with all your "W" heads & valve train & intake. Not to mention what you'd use for internals. In fact, proof is under the hoods all over the place.
