I have a 73 351C Q code with AT,PS,PB, A/c, Holley 750 and Edelbrock torquer intake. I need help with how the vacuum lines are suppose to run. I have the 5 volume shop manual set for 73 but can't locate the info.
Where should the brake booster line be hooked up for vacuum? Mine is currently hooked up to back of Carb. I believe that is incorrect and that the PCV should be hooked up there. Does anyone have a good vacuum diagram for my application?

You can buy a Vacuum Schematic from NPD ($5.95) or such, but on my 70 351C the carb plate is connected to the PCV and the intake is connected to the Brake Booster. I don't need any other vacuum in the car. My shop manual says about the same as yours.

As long as the brake booster is hooked up to manifold vacuum SOMEWHERE you'll be fine.
