so i got a 65 289 in my 74 f100 with a 3 speed manual trans on the column. checked my mpg only getting about 11mpg, but i was kind of goin 75-80 on the freeway and stop and go i wasnt exactly nice, but babied it for the most part. i still think 11 is a bit low, it smells like my carb is running rich. i swapped a 350 cfm holley 2v. you think my jets making it run rich would effect the mpg that much?
