How would you build a low 10’s street car

My good buddy is a old school blower guy,hes building a pontiac 400 with a 671 now. He can do ok on gas mileage but lets face it you can make a turbo motor run like a well tuned 6 banger and with a few keystrokes and some race gas run insane numbers.
That’s what I’m hoping for decent mpgs when not driven hard and power when I want it from the turbos, 10’s is my goal simply because 10’s is my goal call me crazy and what have you everyone’s got a dream this is mine a 10 second car that could behave in the streets and get okay mileage, I feel like turbos would do the trick along with other things in a well tuned we’ll matched combo
