Work Van needs cam???
Hey I have a work van 1988 Ford clubwagon E350 351w fuel injected. I have done a tuneup and everything but only getting 5 miles to the gallon, the van weighs 4950 empty without all my tools and carpet that I haul in it. I was told I could put a work cam into it and maybe increase the gas mileage. I don't have any idea if this makes sense. Any suggestions would help
