Just slap at 80mm+ t6 based turbo on there with a big hot-side housing and all the supporting hardware (BOV/WG/Carb/Pump), let it eat and report back on how the nascar engine holds up. dumber stuff has been done and held together. you probably wont make 1000+ but you'll get your feet wet, see what flys apart and go from there. These are uncharted waters in mopar-land, even more so with ex-cup parts.

I'm going to throw a BW 75mm($400 @ ebay) on a small block MP 3.454in crank($50 @ Carlisle), Lentz 6.2in. roundy-round takeout rods ($150 @ ebay) and custom pistons in a free 318 block. Shooting for 10's for $5k including whatever kind of disposable a-body/f-body/dakota I find on craigslist for cheap.
