Re: Improve mileage 350 with Quadrajet

well in my non professional opinion to get good fuel economy with a truck don’t drive it... naw the main thing is to keep the back 2 barrels shut as much as possible and don’t let them open up and don’t give it as much gas when you are pulling a hill. I learned this the hard way, I drive 125 miles back and forth from work m-f at first I drove it really bad kicking in the back 2 barrels all the time and doing jack rabbit starts, I would drive to work on 3/4s of a tank, now that I drive like a sane human being I can drive to work and back the same 125 miles on 1/2 a tank just some food for thought
