I have used the factory vacumme pump. I only use it for the moisture removal from the oil.. I did eat a couple of pumps up and then I found an article on what you have to do, to modify on the pump...No problems now.. The best thing about the electric pumps is you can mount it just about anywhere... If anyone wants the info on what to modify on the factory pumps ...send me an email at dak697@shaw.ca I'll send it off to you ...takes about 15 minutes to do it

Carlos,
Yes that has been my experience. It also helps if you have a little blow-by to keep the valve covers clean.

At the beginning of the year I switched to Alky with my BBC, and I was scared of all the stories I heard. I got an APD carb (because everyone said they do not milk the oil), and I was told by several big engine companies that i did not need a Vacuum pump. So I went racing with out one. Oil never Milked, I got the temp up to 180* to 200* and shut the engine down, pulled the breathers as well. Never had any Milky contamination in it at all. So from what i was told you do not need one, but I plan on getting one just for the hell of it, I ordered the Aerospace kit from Jegs and it was 735.00 witch I don't see as that bad. A good friend of mine has been running his motor for over 350 passes with nothing done to it at all, not even bearings or plugs. He has no vacuum pump but he does put a 1.5 hp shop vack in one valve cover after he has pulled the breathers and lets it run for about 10 minutes before he loads the car up in the trailer.
