Cam degreeing help me understand!
Not sure why you want to advance your cam another 4° when the custom ground cams usually have the 4° advance ground into them at the start compared to a stock cam.
Try timing it straight up, Cam at 12:00 o'clock and the Crank Gear at 12:00 at TDC. Then your distributor is ready to drop in to fire at #1 at this position.
Then see where your numbers come out. 112 Lobe Centers ???
No easy task figuring it out first time out of the gate. Then if you add more advance than it was originally ground for it complicates it even more.
