Clam Shell Spark Plug Loom

[Justin Slingsby]

I picked up a 42 Plymouth spark plug loom the last time I was at the salvage yard. I like the "clam shell" looms better than the stock one found on my 50's motor. Now I need to relocate my coil. How was the coil mounted in the cars with the "clam shell" looms? Were they always mounted on the firewall? Was there a horizontal mount for them or were they always vertical? If I could hide it I would prefer to do that. What are some solutions you guys have done?

thanks

Justin

I'm not sure what you mean by 'clam shell wire loom'. However, all the early coils that didn't mount on the loom, that I have seen, mounted on the firewall. They mounted at the base of the coil with a round mount plate and were perpendicular to the firewall. They have a pig-tail wire that goes directly to the ignition s/w through the firewall.

The clam shell loom is shaped like a clam shell and has the scalloped edge for guiding the wires out of the loom to each plug...as for what year cars had these I am not sure but have seen a few...

Sorry maybe I was using the incorrect terminology. Anyways the part that I have a red ring drawn around. That is what I referred to as a "clam shell loom"

Justin,

Pre-War MoPars used the "scallop-shell" loom that you pictured. They also had the "lock-switch" coil that mounted through a hole in the firewall, with the hot terminal on the dash-board end of the coil, connected to the ignition switch via and armored cable.

Your firewall mounting is as good as any other... IMHO.

Or you could make a bracket to mount it to the side of the cylinder head, where the oil filter should be... ( ahem: no oil filter ?)

Trucks used them longer. My 46 still has the firewall coil and it should have the clam shell wire holder too. Trucks used the foot pedal starter for a lot longer too.

This shows the coil into the firewall and the "shell"

Naw that isn't a pic of my motor. I still have my oil filter, although that is the next item up for modification. I will show ya a pic of the new loom after it is back from the chromers.

Scottinminnesota where are you from.? That Stude truck you have a pic of, I saw that truck at Hot Rod Hardware's open house in Mantorville. Are you from that area?

[Scottinminnesota]

Thats about 30 miles from Mantorville. I took the picture at the Faribault Heritage Days car show a few years bacK.

My buddy that I go to car shows with lives there. Heres a picture of the chase car in case the Dodge needs parts or fluids.

When I restored a '35 PJ seven years ago, I simply polished the wire loom to a high luster and gave it a good coat of Eastwood's high temp clear paint. It still looks like it was chromed. I did the same with the generator cutout cover.

Your Parts Chaser is a Fiero? Small parts right?

Bob thanks for the tip.

It's his car not mine. He follows the 42 just in case there is a problem. Its a real hoot when we get to some of the informal shows where they park you in the order you arrive. He gets to talk to all of the rice burner kids and I get the dads and grampa's.

The rear hood scoop is MOPAR. So I can deal with the Feiro.

He is running a late model Grand Prix GTP engine. 3800 supercharged, intercooled , methenol injected, custom exhaust, paint and body mods.

It will haul most parts under the hood. It runs 0-60 in under 4 seconds.

Top end is unknown, 1/4 mile is working on 11 seconds and it gets over 25 miles to the gallon on 375 hp.

Last show, we got to haul him to go get a new alternator. That was kinda funny.

Where in Sconsin are you that you came to a Mantorville car show?

[Justin Slingsby]

I had a good friend in high school that had one. Mostly stock but he had added Super Traps and some aftermarket rims. Fun car but essential it was a polished Citation.

I have seen them with Northstar V-8's. Those things hauled. Used to be two of them that would cruise University in St. Paul. When it used to be fun to cruise University.

I am originally from Welch Minnesota. I draw a lot of cars and Tim Gangl, owner of Minnesota Hot Rod Hardware is a big supporter of my work. I designed all of his T-shirts.
