Degreeing a Cam, or not.....

I retested the CL and my 0 on the dampener is within 0.5 degree. My TDC stop was at 12.5 degrees BTDC then rotating all the way around it was at 12 * ATDC. So 0* on the dampener is TDC.

When I did the .050 lift I got 4.5* BTDC again on opening and 57.5* Lift at ABDC for closing. Same as last time. This indicates 10.5 degree retarded opening and 6.5 degree retarded closing. Correct??? Average 8.5* retarded

I got the duration at .050 at 4.5+57.5+180 to be 242 degrees, Close to 246 on the cam card.

When I checked the intake CL, I measured the maximum lift of the intake lobe on the spring retainer, Zeroed the dial and then backed off .100 and then moved the crank clockwise until it reached .030 before max lift and it was at 91*. Rotating past maximum lift and proceeding to .030 after I got 142*. adding them and dividing by 2 I get 116.5 degrees for intake CL. I did it again at .075, I think, and got 68* and 163* summing to 231 and divide by 2 to get 115.5 for intake CL. If we call it 116* then it is 8 degrees retarded from the 108 indicated on the cam card. What is the difference from my other measurements? I had the degree wheel attached to the dampener(thanks @George Jets ) this time. Last time I was measuring with a caliper the distance. Being on a radius I think messed me up and made me think I was close. Am I missing something??? I will have to look at the timing gear receipt and see if it has 8 degree of adjustment before I open the front of the motor.

Tonight I will do the exhaust opening lifts at .050 tappet lift and closing as well. Then I will calculate the exhaust duration . After that I will calculate the exhaust CL and from that the lobe separation.

8 degrees seems like a bunch but I measured several times and the results match closely. I will post the exhaust CL and duration tonight when I get home. Lobe separation also.
