There is debate as to whether there was indeed two "flavors" of the "B" cam. Durations for both flavors were 324 seat-to-seat and 245 at .050 with the lift being .525 which comes out to about .500 after you take off your lash. The debate was whether the LSA was the same between the two flavors. Some reports say that the Ford "B" cam was 112 degrees lobe separation, while the Holman Moody "B" cam was 106 degrees. Other reports say that the Ford "B" cam was also 106 and that there are just mistakes in the literature that have been passed down over the years.
