Mopar 318 and 383 gas mileage?
I own a 69 dart with a 1980 318 with a 4b with a 904 trans and I get about 12mpg I was wondering if that's seemed a little bad or what? Also I have a 1968 383 motor with a 727 trans that I will be putting a 4b on as well what would be reasonable mpg for that in the dart? On the other hand I just bought a 1958 jeep Willy's pickup 2 wheel drive with 3.55:1 gears would a 318 work good or is the 383 a better choice for it. And what gas mileage do you think the willy's would get in that. Any advice on any of these projects would be great. Thanks

Ahaha, if you are concerned about gas mileage (as if you think making either a daily driver is in any way sane or practical), you might as well give up now. Neither option will break 15 mpg on the highway. You gotta realize, those vehicles were made when gasoline was one of the cheapest commodities available. They were never designed with things like... efficiency, in mind. And, on top of that, those motors are missing out on 50+ years of technological progress, that has done many wonders for the automobile.
