Honestly...how good was the 318...mpg / durability / hp
Well, my 318 MPG story involved a 76 B1 blue duster. My end product was a 318 with the two barrel single plane intake, a carter BBD carb, 999 lockup transmission from a Dakota with a 2.76 1st gear, 2.45 gear 8 1/4” rear and factory 340 dual exhaust. I added cruise control from a dodge B van and traveling at highway speeds from Connecticut to Florida and back I would average 25 mpg with that car.
