OK I have this fettish about plug wires on an Early Hemi motor - there I said it!!!! But, CHECK OUT these 2 piece wires I found at the swap meet - the guy was selling ARIAS Hemi stuff and I assume they origionally were used with those, but they fit my M/T covers with stock tubes perfectly. I never knew anything like these existed - pretty cool I think. (not bad for 20 bucks either - IMHO) I'm not sure if Mallory made these or what, but everything else says Mallory on it.
Nice find, do you have a pic on the engine? I think the originals were made of porcelain or phenolic.
Man they are cool! Squeez'in the boots over hemi plugs are weird....some give a definite "snap" of proper fit, then 2 or 3 never do....
Early slant sixes had plug wells too, the wire ends and seals work good on Hemi's and you can chuck the stock cover pieces.
Here's a shot of one on a set of M/T covers - they look kinda neat. Yes - the origionals were typically phenolic and ocassionally porcelain. The phenolic are usually super brittle after all these years - the porcelain's less so, but still you gotta be gentle with them as well - not what I wanted for my digger. All the other (present day) aftermarket ones are OK - but they don't really seal to the spark plugs tubes worth a damn. OK if you have a hood - not so good otherwise. I've mentioned it before, but it usually doesn't go over very well - but Honda boots and extenders also work very well and seal to the factory tubes like they were made for them. FWIW
So, did we ever figure out what the heck these insulators are?? Are these made of a Bakelite type of material or something else??
I have no idea if this is an option or not. But, back in the day I had a shop specializing in Porsches. The 911/930 phenolic plug connector has a 90 degree connection at the top. Memory may be flawed but I think 1000 ohm resistor built in. A rubber boot sealed airflow and foreign matter. Wonder about the length compared to the Hemi?
Hey Scooter - I just sent you an email - most of which was my flawed (incorrect) memory that you should ignore!!! I just re-read my original post and no I remember the Arias connection! I will say this - the "stem" is made out of a plastic - not bakelite. Over the years I ended machining down the top just a wee bit to make them seat better (deeper) which they now do. They've been on my digger ever since I got them and are working flawlessly - I'd LOVE to find out more about them too!!!
Theres plenty of late model stuff that is similar in configuration I wonder if its a repurposed item?
31vicky, I dunno. All the late model stuff I've looked at (even converted - V6 Honda for instance) all had "replaceable" plug wires. Well not easily replaced as they were bonded to the boots, but once you broke that bond the wire traveled down the length of the extender & much like a standard Chrysler piece was easy to replace. What I like about these is the use of "normal" (read: cheap) wires with the added bonus of being able to use 8mm or larger wires. The center of this extender has been molded around a solid wire with a plug like tip at the end. If any modern stuff is constructed like that - I am not aware of what it is off of. The wires you show - look like the 4 cylinder stuff I looked at - all that I found (4 cyl) were too short. For whatever reasons the V6 wires were longer - which was perfect for a 392. These are even cooler - IMHO.
