Where do vacuum lines go on a 1976 trans am 400?

On a 1976 Trans Am with a 400 engine, vacuum lines typically connect to various components such as the intake manifold, carburetor, and emissions controls. The main vacuum source is usually from the intake manifold, which supplies vacuum to the brake booster, HVAC controls, and any vacuum-operated accessories. Additionally, there may be lines leading to the distributor for advance timing. It's essential to refer to a service manual for specific routing details, as configurations may vary based on options and emissions systems.
