    Can someone help me with a ACDelco part number for original 70 Z28 spark plug wires?

    That number probably hasn't existed for at least 45-50 years. You can buy reproduction wires that look like the originals with the correct date codes on them.

    Understand, I found some NOS ones that I was hoping would be correct.

    Hate to tell ya but stock wires are garbage b/c the higher the RPM’s the higher the resistance goes and the last thing you want is lots of resistance in plug wires. My Taylor wires are 40 ohms per foot. You’ll never get close to that in stock wires. At high rpms you can feel the difference. But if you want it for a show car then go for it.

    Thanks for your thoughts. I'm restoring and thought I should keep everything as original as possible. Maybe not though

    I had GM wires and not repop’s a few yrs back and they didn’t last long and ended up shocking me when I touched them.

    If you're 'restoring', go with the dated reproduction wires. I've had a set on my car for at least 15 years and it runs great....maybe not as well as it could with aftermarket wires...but I try to keep mine as original as possible also. I think you only have two choices for dates, either 1-Q-70 (1st Qtr) or 3-Q-70 (3rd Qtr)
