Plug Wire Lengths

[1976gmc20]

When you look at a picture of it, it makes a bit more sense.

Except the distributor is nowhere near that large compared to the rest of the engine.

I always start with the longest one(s) on 1 or 2, then work down and hope.

And yeah most wire sets are hopelessly too long. I think I have some plug wires zip tied to the brake vacuum hose (anything non metallic), and maybe to a heater hose on the other side.

I had a rough running problem and replaced cap, rotor, wires, and plugs as a matter of course. Just kept getting worse and turned out it was a blown head gasket between 3 and 5. So I had a shop do that and a few weeks later it started running rough again! Then I discovered one of the plug wires dang near burned through on the exhaust manifold on that side. Obviously the shop didn't taking much care putting the plug wires back on
