Distributor/Spark Plug Setup

Went to replace the plugs/wires on my '72 with a 350. Curious if this looks correct (picture taken before removing the old wires). Seems like from my I can find online wire 1 is in spot 8? If so what effect does this have on the engine/performance? Obviously going to correct it but just curious.

Re: Distributor/Spark Plug Setup

It looks like the distributor was just installed with the rotor clocked a little more clockwise than normal. It is irrelevant from a functionality standpoint. It would be a hassle to adjust it at this point if all you're wanting to do is replace your plug wires. You would have to set the crank at TDC, pull the distributor out of the block, rotate the oil pump shaft a little with a long screwdriver and then go through the trial and error process of reinstalling the distributor repeatedly until you get the rotor pointing in the direction you want #1 to be. You'd need to readjust the timing with a timing light afterward. Probably not worth the effort.

Appreciate the response. Basically, just reinstall the new wires to match what they looked like before then?

Yes, assuming the current wires are installed in the correct 1-8-4-3-6-5-7-2 order.

Re: Distributor/Spark Plug Setup

There is a conventional way that most folks clock their distributor, but no reason it has to be done that way.
I found this out the first time I swapped plug wires

To prevent cross firing, try not to have the wires touch each other.

I think that's an old wives tale going back to old fashioned plug wires. I can't see any way for the newer thick silicone jacketed wires to cross fire each other. There's a much higher chance of carbon tracking inside the cap causing a misfire than wires touching or laying on each other.

Re: Distributor/Spark Plug Setup

Rules of physics may not agree. Current in one wire will generate a magnetic field and cause current to flow in a parallel wire.
