2011 - Crane Cams

Street roller camshafts are also offered, with their superior
torque and horsepower potential popular among the Hemi
crowd.
Mechanical roller camshafts are available with standard
stepped journal diameters, 2.125” - BB suffix journal diameters
(with standard or SFO (1-8-7-3-6-5-4-2) firing orders for
standard 45 degree, or 48 degree lifter bank angle blocks),
and 60mm (2.362”) - 60J suffix journal diameters (with standard
or SFO firing orders). These larger journal camshafts
have a stepped front journal, so that a standard timing set
can be used. The larger journal camshafts are machined for
3/8” – 24 bolts to attach the timing set, requiring special
shouldered bolts, and two 5/16” dowel pins are installed.
For increased oil distribution to the valve train area, we can
machine the oil groove in the fourth camshaft bearing journal
to a larger size. This can be performed under labor number
98088.
While the standard valve stem diameter for these engines
is 5/16”, aftermarket heads are commonly set up for 11/32”
valve stems. Some heads for supercharged fuel applications
may have 3/8” exhaust valve stems. Verify your valve stem
diameter when ordering retainers and valve locks.
