The first picture is a old Cam Dynamics grind, Crane bought them out when C.D. was grinding and selling better cams than they could You may be able to still get that cam specs. from Crane Let us know what you find out The last and most assured way of finding out what both cams are is to install and degree both of them in at .050 lifter lift and up and see what the actual lift and duration and lobe seperation is EDIT. You could send them to someone who has a Cam Dr. and have them check and give you all the specs for them I've done that also on one lobe for intake and exhaust to get all the info. needed to install and degree that cam. I won't do that now as I'm getting cheaper in my old age, so I check it myself now
