I'm not familiar with the details on this specific motor, how would the bottom end know which TDC it's at? I assumed the distributer was cam driven , but then sixto said the distributor was fixed, so I'm not sure what the deal is here.

You kinda lost me on that last post. When all is lost, there should be factory markings you can rely on like xp190 found on his. Normally it's as easy as putting the crank and cam sprockets at 12 o'clock. If you can't see your crank sprocket then zero degrees on the balancer should be the same thing. On most engines I've done, the cam would fit on the chain more or less straight up, one tooth either way and it was obviously wrong. The cam lobes for the #1 hole should be away from their corresponding valves. From this point you should turn the crank by hand and see the exhaust lobe at peak lift about 240 degrees, or 2/3rds of a turn. If so you’re lookin good. Turn the crank around a total of two times and stop at TDC and the cam should be back to the correct spot again. Too bad you don’t have a good book with fifty pictures of this whole deal.
