Slant Six mpg's?

Wow, those mpg numbers are far in excess of what I get with my 63 Valiant Signet with /6. It has been averaging about 16-17 mpg. It has been tuned up and this is about 2-3 mpg more than I get with my 81 Imp with 318.

Maybe look into a valve job but 1st ..an electronic ignition with a dialed spark curve.

And do you have the 170 or 225?
