Engine build up options

I am currently building a 318 that I am stroking with a 360 crank, it adds up to 348ci with the 30 overbore. I figured on staying under $3000 to do the 318, and am getting close to that mark with the machine work. This engine will be in the car until I get my 408 stroker done, then it will get passed on to the next project. If I were you though, Id stick with the 360, you should be able to get it into the 12s without breaking the bank and keep it a nice street car. The issue with mileage though is gonna be a trick, its tough to get a carburated V8 to produce alot of power and still get good mileage with it. You kind of have to make up your mind, do you want a beast of an engine, or a nice street engne that gets good gas mileage. Myself, I want a beast, my Dart is my hobby car, my Intrepid is my daily driver that gets good mileage and it will stay pretty much stock so that it does.
