Marine plug wires, yes or no

As for the wires, I've run both and I can't tell a difference, but I dare not cast an opinion for fear of being slain. (just kidding, of course) West Marine sells a pretty yellow set that doesn't cost all that much.

I bought a set of 9mm ford racing wires, but Im not sure what ohms they are! they are street and strip car wires!

Mine are Accel.

Are they marine??

If you think at all you wish to add an msd ignition someday, choose not spiral core.

I have been impressed with the quality of the marine MagStar wires. They are beefy, lengths are always right, never had a terminal pull off nor corrode, no radio interferrence. Prices are competitive with most other options.

It makes no differnce I had a set of Moroso Blue Max wires then went with a set from skidim because the atumotive wires where a little short, But I would stay away from the spiral core wires some of the ignition system don't like them and i believe in the instruction of the cil I bought it specificly stated not to use spiral core wires. Like a couple others have allready said the difference is length.

This post prompted me to look around for GT40 EFI plug wires. I'd love to have a set of yellow ones to match the yellow labels on the exhaust manifolds and the GT40 logos on the engine. This would be about as much modding as I would do to this engine . Turns out that SKIDIM has a whole separate set of OEM GT40 EFI plug wires. These wires have a special coil wire and are factory red in color. Does anyone have a cross-reference for an automotive equivalent for these wires? I don't know if the female ends for the cap would be a different size from standard wires, and I'm pretty sure the coil wire is quite different than the non-EFI equivilants.

I believe you can get the dist end either way from skidim, your not going to have an auto eqiv. Marine wires would be to long so they would never have been used on a car to cross reference.

Actually went back and read the Mallory stuff I have and maybe it was the conv. kit I had before the new motor and dist. But I guess I need to look at some spiral core wires, need to get the new exhaust on first tho.

Joel, Im only aware of 2 types of terminals: male/HEI (GM) and female/socket. Not sure which style the GT40 uses, but my stock Prestolite used the female. My DUI requires the male terminals.

Ok, so that narrows it down. Female, I'd presume, since the GT40 cap has male terminals sticking out of the top unlike the typical non-GT40 cap. Now, any guesses on what the ignition wire is called? It can be seen here:

You have to look at the angle of the boot that at the plug, 90, 135/45, or straight, then theres important stuff like the color, and the type of cap, either male/hei or femake socket, and this refers to thw type you see on the cap, your case male/hei others female/socket.


so then do I have a post on the cap? y male/HEI

is there a socket in the cap? y female/socket

the coil wire will usually have no terminal on one end and supply you with both to match any coil type.

spiral's fine.

79, I supplied a pic of the coil wire on the previous page of this post. It looks to be quite different than a std coil wire. The kits will come with this connection?

Thanks Tim, I'm specifically talking about the coil wire, seen specifically here in the lower right:

I just took a look at the engine. Looks like the decorative engine fascia has to be removed to get a good look at it. From what I can see it's just a fairly long coil wire with male 90 degree connections on both ends. That black plastic thing must just be a retainer clip as you suggested.
