You are making assumptions. It won't run, yet you claim "everything is OK" Well there HAS to be a reason. You have been given good advice here. Don't look away from it.
1. Never assume ANYTHING. Don't assume the cam is in time, don't assume you read the marks correctly, and don't assume the cam drive set was marked correctly. CHECK IT
2.....Check your timing marks with a piston stop. That is THE only way to know they are correct
3....Check your distributor. Make sure the weights are free. When "I was just a boy" I had someone with a Chev/ other GM and the then popular "window" adjust dist. THE TOP HAT assembly consisting of the points cam, the advance, and the rotor mount had come loose from the shaft. Yeh. That took some thinking.
