Slant Six mpg's?

Allways the case when building an old car....why not the V8? is the normal cat call. They can and do motorvate the car well.

I never gotten better than 18 on the hwy. but those unknown aged/mileaged engines were not part of the plan. My brother claimed mid 20's at best on the Hwy. His old Dart was one hell of a nice clean 1 owner car.
