I had this cam on a cam doctor but did not trust the numbers as the cam doctor had not been calibrated and looked, well, little rough! And the operator.....
Shows 274-280 duration. I will be spinning this over and checking.
Chart shows .166@106 tdc intake and .178@106 exhaust.
Not sure I follow what that means.

I believe those TDC values are only good when the lobe is used as an intake. If you have the files from the cam doctor you can use those to see actual lobe shape. Many of the comp lobe are not symmetrical when you get down on the closing side.
