Give a man fire, and he's warm for a day. Set a man on fire, and he's warm for the rest of his life :p
OP, as others have pointed out, this will be an expensive and time-consuming project - but only you can decide if the eventual rewards are worth it.
Previous experience stuffing big-blocks into A-bodies definitely comes in handy. It's a lot easier to get info and help than when I did my first 383 Valiant in 1983. No Internet back then, and not much aftermarket support either (except the Direct Connection catalog and Engine/Chassis books) :rolleyes:
