Boss Wrench,

The Victor Jr. intake on my 351w has no provision for attaching a brake
vacuum line. The Holly 4150 has one PCV vacuum nipple.
Can I tee off this nipple to assist my brakes? If not, can I use a
carb spacer tapped for a PCV fitting or does the fitting need to be larger?

You can do any of the three, or drill & tap the intake for a fitting at a more convenient location. Whatever fitting you use should fit a vacuum hose; an ordinary hose will suck flat under vacuum, cutting the effect to the brakes severely.
