Gary,
It is often forgotten that the advance curve of original mechanical
distributors in seemingly good condition is not correct any more because
of tired springs. Also the factory advance curve is an average curve to
make do under all circumstances, style of driving, fuel, hight,
variations in the combustion process of every individual car etc. Anyway
you just have to wait and see if an "original" replacement or rebuilt
unit has the correct curve. You will be surprised how many are incorrect.
You do not always need a dyno. One can experiment oneself with a
electronic distributor ( e.g. the Ignition 123) on the road to find the
curve that best suits you and the car.
