You are kidding ? The camshaft turns at 1/2 the speed of the crank shaft. Firing order is 1-8-4-3-6-5-7-2

As you can see it can either be #1 or Between #5 & #6 with each rotation of the crank. 180 Degrees which is 1/2 of a circle 360 degrees. The rotor should line up #1 every 2 rotations of the crankshaft. To eliminate any doubt. Just remove the timing cover and start from scratch. Will probably take less time and will verify the mechanicals without any doubts.
