I'm a rookie and I'm going to be starting up my 289 soon. I still figuring out how the ignition wiring works and things like that.

I'm aware of three vacuum connections I need to make:

1. Power brakes
2. PCV
3. Distributer

All of these are coming from the carb and not from the manifold.

Are there any others I don't know about?

thanks

George

ps...I'm using a Performer carb and manifold.

make sure to put your distributor vacuum connection on the timed vacuum port. You should invest in a repair manual for your car although it deals with stock engines it helps with technical stuff like that.

If you have an AC setup, all of the options are engine-vacuum controlled. There should be a single line into the cabin for that purpose.

If no AC, you have PCV, advance, and brakes, yes. If you have an auto transmission, you'll also have a line to the modulator on the transmission.

OK...thanks....I'll be starting the engine on my engine cart modified to hold the radiator. So I'll won't initially be running vacuum to the brake booster. The tranny won't be attached so I won't have to worry about that yet and I've got no AC yet...soooo I've got only the distributer and the PCV...

thanks all

Is timed vacuum from the carb or manifold? I'm a steep learning curve so I'll be asking very basic questions like this.

Timed vacuum would be NO vacuum at idle from the carb. Most likely its above the base plate on the carb.

there is usually a port in the upper side of the front metering block that is correct for the dist vacuum. port must be get vacuum from above the throttle blades.

i think all other vacuum devices use manifold vacuum and can come from the intake or a port on the carb getting vacuum from below the blades.
