Bcam to Xcam

[Technick]

With the hyd. roller cams you are all done at 6,200 rpm regardless of the cam, especially the E,B,X,F cams. The lifter are just to heavy for more rpm and the cam profile is all done at 6,200 rpm's. Even tried lighter solid roller lifters on the hyd. roller grinds and still no more power past 6,200 to 6,400 rpm's. The reason why is that almost all cam grinders make the profile to fit the capabilities of the stock hyd. roller lifters, let alone the stock PCM is all done at 6,250 rpm anyway. There are ways around it but it costs a lot more money.
