Can you help me get 12's in the quarter and 15 mpg or better?

Lookin for a car build to mirror or add onto that would help me achieve my goals. Ive got a 1970 dart and i want to do a v8 swap. I want to get 12's or better in the quarter and also get 14-15 mpg or better. Also i want to be able to do this on pump gas and without nos. If it can be done without any forced induction thats a plus but not required
