Degreeing Cams

[CarPsyco84]

For what it's worth, I've had 2 seperate set's of the same cams that idle'd radically different. Dropped in "straight up", i'm sure the accuracy of the lobe centers to the timing pin vary. They were BC280's after all. But I wouldn't be surpised if they are slightly advanced, or both different shortening the overlap, making the idle performance seem like a smaller cam.
