Where does the brake booster vacuum line go? Vacuum canister? Carb? Intake Manifold? Thanks!

If you've got a Q-jet it should go to the bottom rear center of the carb.

It did have a Q-Jet, but now has a Hollye 650cfm double pumper, will it still go to the carb?

Some Holley carbs have a large fitting on the baseplate for the booster line, but not all. If it does not have that fitting on your carb I would recommend that you install a fitting in a 1/2 inch spacer plate and put the spacer under the carb.

There should be a port in the intake manifold that you can use.
