I do not think the post on the Yenko site is right. The last 2 digits describe the autocam so that part makes some sense.
If you look at the factory tune up specs for a stock engine and original distributor, the "initial" timing setting is the key. The sum of the "initial" tune up setting plus the advance available from the centrifugal advance mechanism is equal 36 degrees. I do not know your initial tune up settings for that engine but it is published data.
If I had to wild arse guess, I would go with 36 (total) - 32 (from the autocam ID number) = 4 degrees initial tune up spec. How close am I?
