Might have missed it - but I'm not sure what ported vacuum is. I have a Ford 302 and it has a single fitting that sits in the back of the engine and that's where the brake booster is tied in, and also the modulator on the C4 tranny.

I've got a vacuum fitting on the passenger side of the Holley, and I'm not really sure what's supposed to be hooked there. When I bought the care is was sitting there, nothging connected to it. Anyone know if this is a source of vacuum, or if I should run a vacuum source to it.

Thanks

Dave
