Edelbrock performer 289 Confirm/ID this...

[bassman2]

I can't seem to find a good picture online to confirm my installation of vacuum lines etc...



1) is where I've installed the NPD connector that should hook up the power brake booster line AND the trans modulator vac line... However the Trans Mod vac line hose is too large for the small nipple....

2) Direct center of pic - Is this another vacuum port or do I have an older style intake with a crossover water port?

3) This is on the Carb - threaded hole on the back side...what is it?

Better yet - somebody tell me if I got this right or completely wrong!

OK the pic isn't showing my drawings on photo bucket - weird..

I'm not an expert but I think:
1) For power brakes (prob could use for trans also) - I have a 4 sp w/manual brakes so mine is capped off
2) ? No idea - it's blocked on my performer 289 also
3) PCV connector

I have a T in my #1 that supplies Vac to my AT modulator and to all the factory Heat/AC stuff.
#2 is just another Vac port if needed, if not leave plugged.
#3 is PCV port.

Oh ya #3 is on the carb or on a spacer, not on the intake.

Whatever you prefer..... they are all manifold vacuum....... The fitting on the front of the carb should be pcv.... (also manifold vacuum) , the one on the back of the carb.. power brakes typically.....The ones in the manifold accessorry. They all do the same thing however.

Either side in the back is fine for booster and modulator, just keep the other plugged. Many times the one on the driver side is left capped because of its proximity to the throttle and kickdown linkages. The fitting on the back of the spacer should be used for your PCV. If you have a big nipple in the carb on the front leave it capped.
