id10t,
Sorry, I didn't mean to imply that the 009 was the porsche distributor used in that era of Porsche engine, my reference to the 009 as "porsche type" is based on what VW buffs/parts catalogs call them as a replacement unit to differentiate them from the vacuum advance distributors that came OEM on VW bugs. I believe the term "porsche type" may have originated with Muir, the author of the "how to keep your volkswagen alive" books. From page 90 of Muir's book:

"Just what kind of distributor do you have? Volkswagen has used three main types through the years: mechanical (centrifugal) advance, semi-mechanical advance and vacuum advance. The first two types have been the same all the way, but the vacuum advance distributor has gone through several modifications and has been standard equipment on all models for many years. I hate them! They are another sop to American buyers who refuse to learn to shift a car with a little coordination. This is just a personal beef, so forgive me. I use a straight mechanical advance distributor, called the Porsche Type, which advances the distributor on rpm as the engine speeds up. Most VW race cars and beach buggies use the same. It gives a very good power curve on the VW engine."
