72 360 first start question

Valve timing is different then Spark timing. only way to get correct valve timing is by the timing chain and sprockets. Correct spark timing is achieved by getting the dist in the correct position. Now of course the dist is driven by the Cam, which is driven by the timing chain and related parts. First and foremost, the Cam needs to be lined up correctly in relation to the Crankshaft. If it were me, it would be coming apart and make sure Valve timing is right. :burnout:MT
