318 Magnum 70 Dart Gas mileage

I recently purchased a 1970 dodge dart with a 318 magnum out of a 98 durango and 727 auto trans Its been converted to a 4bbl Edelbrock carb with long pipe headers dual 2 1/2" exhaust with flowmaster mufflers. 4:10 gears with posi trac. 14" Wheels. Wondering what mods i need to do to the car to get decent gas mileage so i can afford to actually drive her around. This is my first classic car so alot of this is new to me.

Easy and cheap stuff to do to make your car a more pleasant daily driver. I'm guessing you need a new heater core since it isn't connected, so get this https://www.summitracing.com/parts/sgt-94503 and this https://www.summitracing.com/parts/cel-65074.

3.23 or 3.55 gears. I have a 2.76 pegleg and I HATE it. My commute to work is less than 10 miles.

And this so you don't get wet feet. Gasket Kits

And WELCOME! =)
