Which engine should i go with

im lookin to get 550 at the crank just somethin i can drive to the track race a lil and drive home without gettin my *** handed to me on every pass. Really i want to go fuel injected but i do not want one of these newer Charger engine in my Car. I want to give the classic muscle look inside and out on this one. Oh yeah to add i'm planing on stroking a 360 thats y im lookin for the roller engine
