Can't seem to get anywhere near the readings I am supposed to. I have the cam installed at 4 degrees advanced. Not sure how to figure that in as no matter how I figure it I am no way near what I am supposed to be. About 10 degrees off. Have dial indicator set up and degree wheel . Figured TDC without any problem. Measuring off the pushrod with a bracket made to support it. Heads off. Going to cut off an old pushrod and plug it to get a flat surface to measure from. Should be more accurate but don't think that will make that much difference. Could not find a cam degree thread here. Using the instruction sheet that came with my  Isky cam.
