This ones kinda right in between your 400 to 500hp mark.
360ci .30 over bore, ported heads to flow 265cfm up from .500 lift with 2.02 & 1.60 valves, Eddy Air Gap, 750 holley carb, Mopar purple cam 292, 9.5 to 1 compression, MP ignition, TTI headers, MP windage tray.

I found a few 360 engine builds and this one apparently makes 450+ HP all day long and is dyno proven. I'm folling it for my build but adding some other stuff in there.
