I think I'm finding that if I degree the cam using their intake opening spec (.050 off the base circle @ 42 degrees BTDC) it will give me a 102 degree center on the intake lobe profile. However, if I take readings .050 on either side of the top of the lobe, it comes in at 96. I'm sure this is due to ramps not being the same on both sides of the intake lobe, but I never guessed it would be that big of a difference. I ran this same cam years ago before I changed to a roller about 10 years ago. I sent my roller cam back to Comp Cams to be checked out after my engine explosion in Phoenix.
