There is no reason for confusion other than getting so far away from the original question as posted. Simply follow the factory manual procedures and call it a day. Mark's distributor is an early 3.3L Euro with the same part number as the one I use.

Moonie's dizzy must work fine or he would have had problems by now. Only his mechanic knows for sure what was done an he is the one to ask questions to, anything else is pure speculation.

The late model distributors that have vac advance are timed the same as the Euro at 4000rpm; they too work using mechanical advance on boost. This function allows for more advance during cruise which is lost when vac goes away. This is covered in the manual for that year. Don't speculate, run the part numbers to see what you have and follow the manual.
