Hi,
I recently swap my 305 for a crate 350 with Holley carburetor 670 and headers (done by mechanic) After getting my service engine to work, I am getting codes 13, 23, and 24. Apparently code 13 indicates something with the O2 sensors, 23 with M/C solenoid, and 24 with the speed sensor.

My main questions are related to codes 13 and 23.
1- is the O2 sensor gone usually when headers are installed, or is the sensor usually replace somewhere in the header? I can always the mechanic....

2- is the solenoid now replace by an intake air temperature sensor, or the solenoid still exist in the carburetor?

Any suggestion in where to start with this journey is appreciated.

The mixture control solenoid was in your Rochester carb.
The ecm is now in a limp home mode.
You might as well pull the check engine light bulb.
The distributor should have been replaced with a vacuum advance hei.

will it affect the car performance?

Ah...yes the distributor was replaced by vac advanced hei

It won't effect performance, you no longer have a computer controlled carb or distributor.

podiatra

got it! so my ALCL connector to get codes is useless?

Yup

Sorry to ask again, but do you know of a ECM set up that I could install that would be able to scan for codes?

See, I am not much of mechanic, but work in my car for simple thing. It is always nice to have code to have some idea what I am getting into.
Thanks in advanced!

It's a waste of funds to even purchase anything since your car is no longer computer controlled.
