408 Cam on the way
Working on camshaft install. I found that when installed in the zero position my intake centerline was 112, not the 106 I expected from the cam sheet. As expected the exhaust was also off at 105 rather than 110. So the camshaft is retarded. But I think I can make it smarter.
Ken had suggested it be installed 2 degrees advanced. That would put it at 104, so I re-installed it using the keyway for 8 degrees of advance. Now the intake measures at 104, and the exhaust at 114. I was puzzled at how that worked out but I think it's right, didn't have time to look into it carefully yet.
The lift did come out right at .321, close enough to .322 on the sheet so I'm sure I got the right cam.
wyrmrider you were right about having to verify how it was ground.
