Inliners International Forums General Discussion Hi Performance Holley 390 and pcv/brake booster lines question

PS:

I've also read that you don't want to use the same source (via a "T" fitting) for both the power brakes and the PVC system. And most say the PVC source should be the one provided on your carb base or, if into the intake manifold, very close to the carb base. Apparently, the thinking is that you want the PVC gases to be spread as evenly as possible to all the cylinders. Locating the PVC vacuum source at one end (or the other) of the manifold presumably causes all those gases to impact just a couple of cylinders.
