Getting hemi 5.7 to 500hp pump gas

As far as actually getting to 500hp i'm not sure what you'll need. I just know it'll be cheaper to only do it once. I definitely feel you on wanting to hear it though. Mine's been sitting on the stand for probably a year now.. Still trying to find time to do the wiring.

You'll definitely want to got with a forged (6.1) crank, a set of worked heads, and a nice bumpstick but i'm sure yoi already knew that.

It's hard to navigate on my tiny phone with terrible internet or i'd try to find some more information for you
