1991 D150 2 wheel drive, 318 and 4 speed automatic. the speedometer hand will go to 100 or to the peg when barely moving. when this happens the odometer is flying as well. not a fast driver but super annoying to see the miles run up evry few second as this is a cherry truck with only 75,000...
I want to replace the original 2bbl. carb on my 1985 D100 with 318 engine. would like to go back to the earlier 70's carbs and wondering if they are direct bolt on or are base plates too different. if so, any recommendations as to what type will swap without having to change intake manifold.
