    5566 is rated 5.0 out of 5 by 2.
    Rated 5 out of 5 by from Just what I needed!! The last set of plug wires I bought for a 350 were barely long enough to reach the front plugs, so the reviews I read before I bought these convinced me these would be long enough. Sure enough, they were plenty long. If I had it to do again, I would buy the set with the plug ends already installed and tailor individual wires to the exact length needed and install the HEI end with the tool included with the set. I put this set on a rebuilt 327 that is mounted on an engine run stand, and it will be a year at least before it goes into my '50 Chevy truck, so I may get the custom fit wire set then.

    I understand the description does not include C2 style Corvettes. However, I'm still curious if this will fit the 327 under headers of a `64 Stingrays. I'm searching for wires long enough for factory loom.

    Asked by: Erich72
    We would recommend the universal sets as you can trim them to length, they are extra long.
