Those crank/cam gears, as well as keyways on the cam and crank themselves are notorious for being off a few thou here and there affecting the degree readings. So just because it says 4 degrees or 8 degrees on the crank gear, doesn't mean that's what it moved. It could have been 5 or 6 or only 2 or 3. It'll have to be checked again if you want accuracy. In most cases, from my experience, you end up a half degree or even a full degree one way or the other and that's as close as it gets.

We too determined about 3/4-3/4 degrees Dwell/slop on either side of the original Balancer line. All the Cam specs. work out nearly perfectly to the self-made Cam card, that we manufactured from online sources.
