I have this van, it's a holley one barrel and three on the tree .It had 3.55 rear gears but swapped them for 2.93s. My plan was to make this van a cross country cruiser pulling my bike on a small trailer. Plan on rebuilding the engine keeping it a slanty and changing to an auto trans. But at under 10 miles to the gallon now I'm having second thoughts . I've owned slants in A body cars and have gotten decent mileage any suggestions on how to get some more MPGs. Would a 2 barrel get more? Cam choice? Do some milling to up the compression ? Go small block? No need to get to technical yet, a few suggestions from someone who's solved this issue. I would love to get it up around 40 MPG but settle for 15, LOL. Anyone have one of these , I would be interested in what kind of mpgs are kinda normal. Thanks AL.
