Y-block spark plug wire routing?

steve fritz

Well-known member
Can anyone send some pictures or give a good description of the correct spark plug wire routing on the 55-59 y-block 272/312 V8.
I bought the wire loom brackets and rubber grommets from Carpenter. The kit includes two round grommets with round brackets , I know they go on the lower rear of the heads. The kit also includes two other brackets which have more rectangle shaped rubber grommets. One bracket has a longer neck on it than the other bracket. My question would be where do these two brackets mount??
Shop manual actually shows THREE of these flat grommets , and the picture is not real clear as to where they mount.
So if anybody has a nice picture of the back end of a complete y-block with wiring in place , that would maybe answer my question.
Thanks in advance for any help.

You are on the right track on the right parts to use, but it has been a while since I did mine. Look up Tim McMaster on facebook and look at his pictures, I'm sure your questions will be answered.
 
miker98038.....thanks for the website attachment....had some very nice pictures to show how to mount those two brackets. I appreciate your help!

I just did my wires with new looms. I thought it was going to be a nightmare, but with the help of the pictures it really wasn't that bad.
 
Guys....just as a quick follow up to my spark plug wire routing . Today I worked a bit on the y block wires. Looks like I will have to share one of the mounting bolts that also hold down the bottom part of the throttle linkage to the back of the y-block.
Not a problem , but that looks like the only option to mount this bracket/rubber grommet on the wires going to the left side of the engine.
Here's a couple pictures......pictures will follow later.

If you had a shop manual, it would show you many things that previous owners have left off that should be there, and the shop manual provides good illustrations and descriptions of how the parts are assembled.
Not that where're not more than happy to answer your questions, but having a '55 wagon all apart and not having a shop manual might be asking for disappointments later. It is a good learning tool.
Steve, You need to look at your private messages regarding the fuel sending unit.
 
When I was detailing my 292, I went with the stock wire looms, but had a very difficult time squeezing in my 8mm wires. I'm running a Mallory Unilite distributer & a high output coil and felt the need for larger wires. So I'm still looking for a stock style looms that will accept a larger high performance wire for next time.

Too late now, but - http://www.taylorvertex.com/spark-plugs/cloth-covered-spiro-pro-wires/

If you keep the insulators in the bracket (on the bench) (to hold steady) do you think you could run a drill bit through to open up the holes?
 
So Taylor wires is a good option for next time, as for drilling out the rubber, I did think about it, but thought it would be too thin, and or shred the center portion out. The hard part with the larger wires was squeezing the metal brackets closed in the difficult to get to locations and start the bolts
