Plugged distributor

[green 66]

Why would you plug your vacuum advance at the distributor?Mechanical advance works really well for me!

Went bad again?

I kinda don't understand the question.

Yeah, I think he means some don't run a vacuum advance.Now that depends on what you do with you car, and or if your distributor has been reworked. My Valiant is more of a cruiser, it's hooked up and the distributor is stock electronic. Now the Hemi Car the distributor has been modified and mainly see short trips and allot of wide open throttle.Plus some guys do it to limit advance to keep detonation at a minimum to run pump gas. My 2 cents.

I just see a lot of guys plugging them.My advance was bad(thanks to Halifax Shops for fixing it) since it is working correctly car never ran so good

I think the majority of people who disconnect the vacuum advance or their street cars simply don't understand them.

This is my point

Some people need to get a good dist. book and read it. You have to understand the complexity of it before you can see the simplicity of a vacuum/mechanical distributor! Back in the day this was an engineering marvel in its own right and they perform an amazing job when operating properly. Total timed or mechanical dists. are for racecars or racecars driven on the street and very high performance engine can run great on the street with a mech/vaccum dist. I don't think just everyone even begins to understand ign. timing- gearing-load-rpm-incline-decline and part throttle cruising in a /6 or a race hemi at any stage of tune. The factory service manual would be a great place to start. good luck all hotrodders. Oh yeah, I presently have 2 B-body cars, a 64 and a 68 and one is a B-512 and the other is a rb440 and both 4-spd, both have MSD with one mech., and one vac./mech and I prefer the vac/mech for various reasons but I'm also not chasing numbers at the strip.
