Emissions control delete

This 80 K5 is LOADED with vacuum lines that I know are part of the whole smog pump bull ****. Can anyone tell me what I can delete to clean this engine bay up? I want to make sure I don't end up removing something that will affect the way this truck runs. I know it will and should run better once it's not being restricted

Re: Emissions control delete

It would probably be easier to ID what you need and delete the rest. Brake booster, HEI, PCV valve, cruise if you have it, one to the "black ball" on the passenger side firewall that goes to the HVAC controls - what else?
