Ready made set of spark plug wires for our trucks? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Jobe72 · 07-09-2010, 10:41 AM

I've got a 350 with HEI in my 72 GMC with stock manifolds.

Is there a spark plug wire set that I could get over the counter at the parts store today that would work with this combo? I'm thinking something out of a vette or later model truck might work? I have a custom set of wires waiting, but don't have the time and I need to replace my wires now along with the plugs.

Any help would be greatly appreciated.

The answer is yes. Now. Have to remember specifically which years, but if I remember right the '73-75 vette wires will work. They had the hei and the ramshorns still. I'm 99% sure that's the right years. The truck ones don't work since the changed the exhaust manifold design. Hope this helps!
