If you want both(who doesnt) consider fuel injection or swapping in an LS engine. AP72 can help you with wiring and harness questions,and,,,, a 5.3 with little work can produce 340 hp and return decent MPH
An LS is just not what I want to do with this car... at least not any time soon. I have considered the new MSD Atomic fuel injection... but at best it'll be a year or so past the motor build. Only got so many pennies I can throw at once.

Fuel milage isn't really my "focus", or I wouldn't even consider the 383. I just don't want it to be ****ty. I'de still rather have a strong running car that get's 11mpg over an "ok" running one that get's 15mpg.
