What emission controls can you remove from a 1977 305 without negatively effecting engine performance?
legally-none
practically-all except the PVC valve.
i would hook timing up to constant vacuum. ste base timing about 10 degrees and gofrom there.
I'm sorry, but NEVER hook the vacuum advance to direct vacuum. Always use a ported source, (above the throttle blades) If you have the vacuum hooked to a direct source you build an instant bog into the car from a stop. I fix maybe 2/3 cars a week in my Emission Shop with this problem. Been doing it for 23 years. They'll usually run with high HC at the Smog check, too.
What else can I help you with?

What is the purpose of combustion noise sensor in car engine?
combustion noise sensor signal use To reduce the emission and improve the performance by changing the ignition timing. When the engine is accelerated the timing can change, you get a pinging noise. It senses that and adjusts the timing to compensate. They didn't have this in older engines without electronic ignitions and you had adjust the distributer to find a happy medium setting. It really imporves performance and power. Its not the same as an exhaust sensor that reads the unburnt fuel level and adjusts the fuel to lean out the mix. The exhaust sensor is more for the emission controls.
