67 Dart - 273 - Advice Needed

This A body stuff is getting addictive... I just picked up a VERY clean 67 273 Dart - Auto. I have a 318 and a 360 4 brl Premium motors sitting under the bench. Since I am not a small block person (B-RB person) could some of your guys give me some ideas for a good strong streetable combo for this thing? Thanks for your help in advance.
