Factory correct plug wires

1 Attachment(s)

Hello, does anyone happen to know the part # for the factory correct plug wires for a 72 350 engine, or a good source? I feel like the ol gal needs a set. Thanks in advance.

Rockauto shows ACDELCO 9508N or 508N for 72' C10 350. I used ACDELCO 9508N on my 72' K2500 GMC with a 350, fit perfect.

Re: Factory correct plug wires

When you change your wires consider posting the length and plug number they came from. For me it has been difficult to get the lengths in the correct position.
As difficult as it is to get them under the motor mount I would appreciated only doing it once. :)

Thanks for the info. I didn’t think to check there.

Thanks for the tip. Getting them routed through the mount is my biggest fear, and reason I haven’t tackled the job yet.

Looks like the 508N are what I will get. Might have to find a NOS set as I am wanting the correct Delco, and Packard suppression markings on the wires. Guess I’m picky haha!

When I did my restored my jimmy the set I got were long enough to go through the motor mounts. Now my motor is out should be able to get a free set. Have to check and see where I got them.

Re: Factory correct plug wires

These reproduction wires may be something to consider. They are dated 1-Q-72. They also have 3-Q-71. Both would be appropriate for a '72 truck depending on truck manufacture date. I don't have personal experience with them, but Lectric Limited has a pretty good reputation.

Re: Factory correct plug wires

The repopulate date coded wires are the pieces you are looking for. They are a little pricey compared to generic replacements but I have them on 4 trucks and are always perfect fit and correct markings

Re: Factory correct plug wires

When you pull the ones back through the motor mount tie some sort of string or something on them and then tie that to the new wire. Will help you snake it back through a bit easier.
