yeah, i have a bad lead foot
. you're right though about gas mileage. i had a jimmy w/a 4.3 and i bet it got the same to +3 miles a gallon better than a 350. it depended on how i was driving. 1-1/2 to 2 MPG almost makes it not even worth it
. the 4.3 in it runs like a sewing machine though so unless it blows i guess it's staying
