C2:67 Spark Plugs-What's the difference

I think that we're talking about 2 different "Packards" here (although, going WAY back, there may have been some "linkage" I'm unaware of). The "Packard" being referred to here is the old "Packard Electric" which became a division of Delco years ago. This division manufactured many of the electrical components of GM cars, particularly wiring products. As far as I know, the "Packard Electric" brand still belongs to GM or DELPHI (the spin-off company that now includes most of GM's old parts-manufacturing operations).

While Kanter may have purchased some rights to the Packard Automotive Manufacturing Company, I don't think that they have any rights or connection to Packard Electric. Like I say, there MAY have been some connection between the operations in days of yore, but there hasn't been in the past 50 years that I know of.

Re: C2:67 Spark Plugs - AC 44

In real life, we cut the daylights off the heads and never had a plug hit. Of course, I can't tell you which plug we were using at any given time. I have some AC 45S plugs that came out of one engine (327 I think), but as we cut and did other modifications, we ended up going colder on the plugs, running AC 43 plugs eventually. The 302 did have 12.5:1 TRW pistons and the first set of heads were cut .090 and the second set were cut 0 - .100. We were running AC 43 in it as we were spinning it 8500 and up much of the time.

I think we might have had an -S plug touch in it, but we were far from stock configuration. Seems like we put a set in and the car had an almost instant miss in the shop.

I agree with John. I had fouling problems with ..

the 70 LT-1 I owned and changed to the R45S and no more issues. Same goes for my current 67 L-79.

Jerry -

I don't recall the spec (5,000 ohms per foot or thereabouts?); what you're really looking for is "opens" (lack of continuity).

Re: C2:67 Spark Plugs-What's the difference

I don't recall an exact spec, either, but I agree with John that it should be no more than about 5K ohms/foot. Look for a consistent per foot reading on all wires. Any that are significantly over this should be replaced.

I checked out the website, & he says original tye. I left a message for them, but waiting on response. I'll let you know what they say. I sorta remember him telling me at a show he had the Packard cables.

Re: C2:67 Spark Plugs-What's the difference

John/Duke,

Just got my new set of LL plug wires today and tried to test them with a 1 1/2 volt radio shack volt-ohm meter. Adjusted the needle to 0 ohms at full contact with the leads. Tested each plug wire and got no continuity with each plug wire, the needle never moved from the infinity side of the scale with the dial set at x1K ohms. Am I using the wrong kind of test equipment or testing them wrong.

If I put the two leads together, the meter goes to 0 ohms or full continuity. Contact end to contact end of the plug wires, no movement on the scale.

Advise appreciated,

Got a note from Stu Kanter- they are generic
