Hello. I was looking at the aluminum manifold for sale at P.I. Motorsports. If I bought that manifold, what would I do for a vacuum connection for my brake booster?
Thank you

I T'd off the large port on the back of my Holley and ran it to the booster and the PCV valve.Seems to work fine
Mr McCall's solution is fine, or drill a hole & tap it for 1/4" pipe, then add the appropriate brass fitting directly to the manifold plenum. Either works OK
