There’s been a lot of confusion around the discontinued Boss Racing Cam part numbers and labeling. Misnomer is the
M6550-BEXH 13mm lift and 290 degrees duration and M6550-BINT 13mm lift and 263 degrees duration are not stock Boss factory cams. Many shops thought these cams were factory cams but specs are higher lift and longer duration.
Ford racing tech said there were not part of the CJ racing program.
