Poll - How far away from home do you drive your classic?

I just updated my signature to show my setup but its a 225 slant six with a TorqueFlite and 2:76 axle. About 30 years ago, I put in a Direct Connection high lift, short duration cam (PN 4120243), 318 valves, 340 valve springs, some mild porting, and a Carter AFB. I upgraded to a Quadrajet last year and to HEI this year.

Miles per Gallon?
