    Hi All,

    I'm new to the forum and have a question for you guys. I am upgrading my 72 with a 350 from points to HEI. I know that I need some more "substantial" wires and am wondering how I know which wires will suffice. Also, does anyone have any spark plug recommendations, as well as spark plug gap specs?

    Thanks a lot!

    Excellent. Also, what do you typically gap your spark plugs to? I've read that HEI should be around 0.045. Any thoughts??

    .045 is fine.

    Good deal. I installed the new HEI, plugs, and wires, and she runs like a champ. Thanks for the info everyone.
