My 528 has dominator intake and 1050 dominator carb. MSD pro billet distributor has vacuum pot.
Current have a vacuum motor to run my power brakes, however i am in the process of removing my booster and running manual disc brakes. Have all the parts ready.
Here's the question: could i use the vacuum motor that is already there to run a vacuum distributor?

do you mean as a vacuum advance for your distrib? why bother? you have a 528 cubic inch engine and a 1050 Dom carb. Vac advance is designed for better emissons and mpgs.

no, the vacuum pump would not simulate the operating conditions of your engine. Your dizzy needs a vacuum signal generated by the engine.

No. Cap it and forget about it.


Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

The reason vacuum is used for advance is because depending on the load, the vacuum readings go up and down. You don't want the added vacuum under load, because it will detonate. And having the added vacuum while not under load will keep the plugs cleaner.

With a vacuum pump, it does not change when under load, it is a constant vacuum.


Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

In theory you probably could do it if you just flicked a switch to run the vaccum pump when on a steady cruise on the highway. However with a 528 with a 1050 I somehow don't think highway cruising is what the car was built for...
