Let's talk G3 hemi cams
Maybe look at what the Demon and Red Eyes are running for an OEM cam? You won’t have the advantage of VVT so maybe adjust the centerline or something. You will be down on displacement a little and maybe cylinder head flow, but even if you are 200 hp lower than one of those, I would call it a win.
I know there is a guy on ChallengerTalk.com that did a Hellcat cam swap in his 2015 RT with a blower and seems to really like it.
