318 Timing Chain Question.

If you hold the chain and sprockets in your hand by the upper sprocket. Align the marks 6 on the top sprocket and 12 on the bottom sprocket . Let it hang. You can turn them any way you want to get them to go on. As long as you don't jump a tooth top or bottom it will be in time . You may have to turn the crank to get the keyways in the right spots to go on but the timing chain will be in time.
