Vacuum Hose Diagrams for 1968

Q: Vacuum Hose Diagrams for 1968

Hello all! I am in the midst of rebuilding my 1968 firebird 400 conv. (little by little). I am working on the engine for now, while I am waiting for my Year One parts to arrive… I read the message a little earlier about overheating. Which unfortunately, my poor car is doing! It mentioned the vacuum advance hose being on ‘manifold’ rather than ‘ported’ vacuum. I was wondering if anyone might be able to point me in the right direction for a Diagram of CORRECT vacuum hose routing (or some dang good pictures), for a 1968 400. It seems the owner before me, decided to just cap off almost every vacuum port available… so this could be one cause of the overheating… ?
