V8 plug wire separators


Packard8

Recommended Posts

The recent dual quad thread and the pix posted bring up another question. Which plug wire separators are correct for which year? The 1955 dual quad setup Carbking posted shows the short open top style, my ?56 Carib has the longer thread-thru style with the round rubber insulators/holders. However, I have a ?55 Pat with the original engine (numbers matching) that has the longer version like the ?56. Was the change perhaps a ?running change? that spanned both years?

You need the wider ones. They help prevent crossfire. And yes they have been fitted on a lot of 55's. My all original 56 400 had the small ones and I had problems until I installed the later type units. Joel

No, that is the narrow configuration.

I have never had problems with narrow type bracket (on '56 Clipper), since I replaced the plug wires when I got the car.

Here's the wide type on a '56 Executive: See Attachment

It's my understanding that only '56 Seniors (including Executive) used the large bracket and '56 Clippers had the smaller one, like '55s.

Not so, my all original one owner 56 400 had the narrow ones from the factory. I believe there was a service bulletin out on this issue. Joel

The wide bracket was introduced in Vol 30 No. 3 of the Service Counselors (March 1956). It was recommended as a remedy if a cross-wire ignition problem was observed. The brackets were never mentioned as being for Seniors or Juniors, but only as a replacement for the cross-wire problem.

Thanks for the Info. <img src="http://www.aaca.org/ubbthreads/images/graemlins/smile.gif" alt="" />

I knew if I made a statement, one way or the other, someone would come forward with the Info we needed. <img src="http://www.aaca.org/ubbthreads/images/graemlins/wink.gif" alt="" /> (They just love to correct me) <img src="http://www.aaca.org/ubbthreads/images/graemlins/crazy.gif" alt="" />

Thanks Randy,

I'll take the S/C as being the final word that either is "correct" for both '55 & '56. But like I said, I think the wide ones are sexier! <img src="http://www.aaca.org/ubbthreads/images/graemlins/grin.gif" alt="" />

I wouldn't want it any other way. <img src="http://www.aaca.org/ubbthreads/images/graemlins/smile.gif" alt="" />

It's just that it seems we sometimes have to Drag the Good Data out of you guys or maybe it's that we don't wait long enough for someone to get their brain wrapped around the question? <img src="http://www.aaca.org/ubbthreads/images/graemlins/blush.gif" alt="" />

The chrome units you are talking about were not factory. Bob Berg many years ago reproduced these items and had them chromed because they looked better. I have a set I bought from him about 20 years ago. I decided to put the black original painted ones on my 56. Joel

The rubber grommets in good condition are the key. Mine were NOS and in great shape. I looked in Steele's catalog, but there is not enough of a description to identify them. Maybe if I emailed him with a picture and dimensions they could respond. I'll take a pic today.

The critical issue on wire seperation, regardless of hangers, is to be sure that #5 and #7 plug wires do not run parallel to each other by any less than 1/2 inch nor cross each other an odd number of times. If they must cross then be sure that they cross an Even number of times and each successive cross is the opposite direction. Otherwise a slight symptomatic miss will be experienced. This is true for all engines firing 18436572.
