Re: Brake booster vacuum
only if it is on the carb base - it must be a steady vacuum signal, not ported, regardless of truck rpm. That is why the factory used the intake manifold port location primarily.

Re: Brake booster vacuum
If your carb has the large fitting at the rear of the base, yes that's good. Q Jets used that location with a large screw in flare fitting for a hard line to the booster.
