Degreeing a Cam, or not.....

Exhaust info.
Opening at 54* bbdc closing 18*atdc 18+54+180= 252 duration. spot on the cam card specs.

BUT, 18* should be 10*atdc and 54* should be 62*bbdc

Finally, I measured the Exhaust CL at..030 before and after max lift 43 * bbdc gives 137* plus 77* =214/2=107CL
Again, at.050 145*+71*=216/2= 108CL

Could it be possible that it is 8* off? both intake and exhaust say so. Any other verifications that I can do?

The 116 for intake and 108 for exhaust do give me 112 lobe separation. AND in case anyone is thinking about it??? I know enough that the intake is the one coming from the EFI and the exhaust is going to the header, It just seems that the numbers are backwards.

I am perplexed and figure that more work is on the way. I look forward to it.
