Setting crank to the cam on my 79 Spitfire

Never done this before. I was not understanding the book. I swear they write directions thinking you already understand what your doing. Not funny. It took awhile before I understood the changes the cam sprocket was making at the crank. The cam sprocket has 42 teeth, 360/42=8.57 degrees per tooth, and then there is a 90 degree rotate 4.29 degree change, a right to left flip 2.14, and the combination 6.43 degree. Your changing from 2 to over 8 degrees with the quarter tooth, half tooth, three quarter tooth, and full tooth position changes. The crank sprocket has only 21 teeth. Something else was going on too, I discovered that way too late. I set my cam timing by the Equal Lift On Opening method, cylinder #4, valves #7 & #8, that gave me a place to start, then the crank dialed in with the cam using bolt movement in the sprocket holes. Intake & exhaust valve max lift occurs at 110 degrees with my cam. Other vids of that, and the ELOO. Timing was checked later with a printable degree wheel, I had to know how close is was, to sleep at night. All moving metal contact parts better have assembly lube, or grind something if you don't.
