    Changes spark plugs 8-5 yesterday and decided to check resistance of the wires at that time. Results:
    #5; 20” long 6.0 ohms on 20,000 scale
    #6; 24” long 6.2 ohms
    #7; 29” long 5.4 ohms
    #8; 34” long 5.5 ohms
    Is there a chart that shows the correct resistance per wire?
    I have a ‘95/ 2.7 355. Wires show no cracking and are very pliable.

    Those are 5 - 6 thousand ohms in the range of 20,000 ohms. They are OK.

    Thank you Gents. Reinstalled existing spark plug wires with new plugs. Runs great, idles smoothly.

    Do 348/355 V-8s have the same spark plug extenders that 308/328 V-8s have?

    No, they figured out their mistakes.

    And some of us in the 308 world also figured out a way to eliminate the stupidly unreliable extenders as well.
