Hey there, Changing out the spark plugs and wires on my 71 455 and was wondering if anyone out there has a wiring diagram for that. Not saying I don't trust the guy that I bought it from to have it right, but I don't trust the guy that I bought it from to have it right. Also the wires he has on there now is not the right length and is just laying on top of the valve covers/wherever they fall. Any suggestion on how they are actually supposed to be routed? Thanks in advance.
1-8-4-3-6-5-7-2 Just go clockwise from #1 they should go into holders that attach to the bottom valve cover bolt studs.ill find a pic.
If you want the plug wires to fit like they should, buy a universal. You cut the wire and install the distributor end. This is how the plug wires should be arranged in the cap.
The big deal is to keep #5 and #7 well-separated until they plug into the cap. The "official" routing will be shown in the service manual you need to buy. I suggest eBay.
I bought plug wires for my BBB from Lectric Limited. A bit pricey but fit like a glove. https://www.lectriclimited.com/
Here is how I routed mine on the drag car. I used the plug wire mounts from T/A. I wanted to keep them off the headers but it's the same with manifolds. These are Taylor Spiro-Pro cut to length wires with 135* plug ends.
Thank you Larry, I've bought universals and have someone making them up for me now. I appreciate the help!
Thank you Phil that's a really nice setup you have! Is that a little self on top of your headers you have your wire clusters resting on?
That's not a shelf but it's part of the T/A wire holders. They bolt up with the valve cover bolts and clamp the wires in place. Not sure what their part number is but I think they were @ $80.00...
