Slant 6 most mpg's
The challenge for You is that Mopar already "extreme mileaged" it for You, so improvements on the basic package are nearly impossible, the base timing for that package is
12deg BTDC(man & auto) vs. the std. 6(man) & 2(auto)deg BTDC. The carb. calibrations and timing curves are already pushing the envelope. If You are willing to run a
higher octane fuel, moving the compression up to 9.5:1 will probably be the only thing w/o a switch to FI and electronic engine management, to improve the stk. #'s.........
