OK we tried to degree my billet roller camshaft in last night. Specs are:

262/266@.050, 105.7 LC intake and exhaust, .665/.625 lift w/ 1.5's

We tried it the Comp way and the Crane way and came with 108 both times. How often do you guys wind up a few degrees off when you degree a camshaft in? Is there anything we could be missing, or should I just advance the cam timing 2*?

 

My accuracy in doing this is ~2 degrees. IOW, if I repeat it it, the results will vary by that much. Did you repeat it using the same method and get 108 each time? If so, you are very good at this and your numbers are probably right. If I wanted 106 I would be hapy with 105-107 (on repeated measurements). If it were off more than that I would adjust it. So, if you get 108 repeatedly, I would advance the cam to get closer.

I could definitely see how it could vary. We did it the comp way and the crane way, I think the first try with the comp way we got 108, with the crane way we got the high side of 108, like 108.7'ish. I think we might try degreeing it a few more times tonight and see how far our results vary. So if we keep repeating at 108, it looks like we will be advancing 2*.
