If you run across a cam from a 94-97 E or F series (van or truck) snatch it up and stick it in there. These are great street cams with a carb. A set of 1.7 rockers will boost the lift specs in line with the HO cam. Same cam was used in the 96-2001 Explorer/Mountaineer 5.0 too. These cams have just a tad less duration than the HO's.
