Estimated Gas Mileage - Not worried but Curious

[SouthernDart]

Hi Guys - my 75 Dodge Dart Sport Coupe Resto-Mod is almost done, and I'm curious what your "Guesstimates" are on Gas Mileage.

Here's the info:

1975 Dodge Dart Sport Coupe / 318 w/ 500 CM Edelbrock 4BBL Carb / Comp Cams Camshaft & Spring Set (Mid Range Torque - nothing crazy) / Edelbrock Performer Air Intake Manifold / Hooker Competition Headers / 4 Speed A833 OD / Rear End is Ford 8.8" 4.1 Gears.

Since I'm in the Andes Mountains my altitude will be 2500 Mts (roughly 8200 Ft).

Any & All info / Guesses welcome.

My magic 8 ball says 12 MPG. It says you wont be in overdrive very much because of the mountains.

You would be the man to talk to about elevation. You are in Lyons correct?

Hard to even guess without knowing the actual cam..... 'Mid Range Torque - nothing crazy' does not mean much.
