If you keep your carb, then almost all other parts of the"Smog" system will need to be in place ( ECM, Dist, EST, O2 Sensor, etc..). You can delete the smog pump and associated piping, etc, as it is not monitored by the ECM. The EFE is also not monitored, so it can be deleted, but as stated I would wire open the valve in the passenger exhaust manifold just to be sure. It should fail in the open position.

You've probably seen this, but for reference..
I'm surprised that Remove Smog Stuff thread is not stickied

I'm not. Tampering with a vehicle's emissions control system is illegal under the Clean Air Act (CAA). The CAA also prohibits manufacturing, selling, offering for sale and installing aftermarket devices which effectively defeat those controls.

While technically some are covered under exemptions due to age, most of us aren't, if you have a car that came with smog, it should have smog. But without government testing and oversight, like yearly emissions testing, it's left upto local/state authorities to enforce. Which they mostly don't.

By 'stickying' the delete, you go from public sharing of info, which is a First Amendment protected activity, to an endorsed Activity, which isn't covered and could land NECOA in legal trouble, like what happened to the Diesel Brothers who had youtube videos proving violations.

1975 and up

section on Installation
When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently. Most designs of the time therefore included secondary air injection, which injected air into the exhaust stream. This increased the available oxygen, allowing the catalyst to function as intended.
