you could walk the cam and distributor, one step at a time. (text book ways)
IN school for 50 year, we did that, 4 cycle engine, rules.
turn the crank to TDC, firing #1 zero degrees. (front cycl is #1)
then off the distributor cap, even have the valve cover off, so see the valves move, and lash loose at TDC.
then know that he cam turns 1/2 speed of crank
the crank turns CW, and every 180degrees a new cylinder is at TDC. to fire, 1,3,4,2, order clockwise. (this order is not like any boxer engine made...)
the Cam fires every 90 degrees turned 1/2 of 180 crank is 90, easy no?.
so if you can see the cam cog wheel to you know that the E marked spoke at 12pm for #1 firing or #4, (lash loose tells you which it is or cam lob actions)
The TDC cylinder firing has loose lash.
so you walk the crank shaft 180 degrees at a time, and see what the cam cog wheel does? and what the rotor does you know it is timed right or wrong.
Im sure you have the distributor timed wrong, or the wires laid down wrong, the GM book has this wrong, so.... do not read it.
I bet if you did that test it would fail, in some way.
the rotor spins CW just like the crankshaft, do not get this wrong and put the wires HV down wrong.
The rotor must land on a cap tower HV connector location at 1,3,4,2, if not , it is timed wrong.
