I had trouble reading the picture and figuring out how to best make comments, so I'll just make a list.
If you have no EGR or any temperature controlled vacuum switches, you should be able to get by with these lines.
Vacuum
- 3/8" vacuum line from carburetor base over to power brake booster. Stock system has a steel hard line screwed onto the carburetor, and it reaches about half way over to the brake booster, then you add the rubber line to fill the gap.
- Two small vacuum lines, usually connected to a fitting on the intake manifold (using vacuum tree or vacuum tees)
-- to HVAC reservoir/canister mounted on the A/C plenum. If you have A/C and don't connect this line, your controls won't work right because the vacuum motors won't work.
-- to modulator for the TH350; not sure whether the 700R4 or TH400 needs it
- One small vacuum line from the carburetor to the vacuum advance - use either ported or manifold vacuum from the carburetor, depending on what you need
Emissions
- 3/8" PCV hose from carburetor over to PCV valve in one valve cover. This hose is pulling air out of the crankcase and removing moisture. Do not get rid of it.
- Other valve cover needs either a breather cap, or a hose connection up to the side of the air cleaner. This provides the air that is being pulled into the crankcase.
You might also need to provide vacuum to the cruise control servo, thermac vacuum motor in the air cleaner, or other devices. However, your engine will still run if these devices are not connected.
