Getting hemi 5.7 to 500hp pump gas

good points..ty for the replies and info.
The tick, is a mystery obviously without it running. They guy I bought it from actually did the swap for a client of his, he sold me it for $200. I jumped all over the engine regardless of the tick.
It turns over, there is no leaks, no metal, no nothing.
the rods were all straight and true. Valves worked....im guessing is just a lifter.
I know my 09 charger has a slight tick, but its nothing to worry about, even dealership said its nothing.... that's the "normal tick" ive read about.

way i figure it....if that's all that's i wrong w it, I stole the engine...if its something more serious, I still am doing great for only spending $200

So if i just went stock ecu, cam, some forged piston....what is a realistic HP expectation?
if i decided to stroke it, then what?
