  • LT1 spark plug wires....stock or over the valve cover

    Okay its time for wires and I am told the replacement is a big time PITA.
    How much easier is the OVC setup to install and where can you get direct install wire kits without having to splice and all that crap.
    Also are the OVC type more aftermarket header friendly, I might be doing headers soon.

    I have a buddy of mine with the OVC's and he says they are the greatest thing since sliced bread. He also has Hooker long tubes so I know they work. I don't know how much crap he had to go through to install them though, so can't answer that one.

      OVCs are meant for headers. You will burn them up if you try it with stock manifolds as they will lay right on them.
