What could be the cause for a 1972 Chevy 350 CI engine to not run when it has HEI ignition and EDEL carb hooker headers?

1. Check for spark:

- Verify if there's spark in the spark plug wires. Remove one wire from the distributor and hold it near the block while someone cranks the engine.

2. Check fuel delivery:

- Ensure that the fuel line is properly connected to the carburetor and that the fuel filter is clean.

- Check if fuel flows out of the carburetor when you manually operate the choke.

3. Verify ignition timing:

- Ensure the distributor is seated correctly and the timing is set properly. Check your specific engine's timing specifications.

4. Ensure proper air/fuel mixture:

- Check the carburetor's float level. An incorrect level may cause it to run lean or rich, affecting engine performance.

5. Inspect valve train components:

- Check the valve clearance and adjust as per specifications if needed.

6. Check the HEI ignition components:

- Inspect the ignition module and distributor cap.

- Ensure the coil and spark plug wires are in good condition.

7. Check Hooker header installation:

- Ensure the exhaust system with Hooker headers doesn't hinder exhaust airflow or cause interference.
