Default spark plug wiring diagram

Does anyone have a diagram of the plug wiring diagram for a 66 327 350hp? I have a service manual but apparently I am blinder than a bat cause I can't find it.

What specifically are you in need of?

The clocking of the wires on the cap, the routing of the wires down to the oil pan and back up through the motor mounts to plugs 1, 2, 3, 4, the order in which the 4 wires are routed through the loom on each side?

Etc. We can help, once we know more about what you need

Try this diagram, #1 plug on cap is after the window to adjust pints if I remember correctly... My '55 cap does not have the modern technology of those later caps

jeff, I have a dead miss. The plugs are new so I thought that I could have a plug wire connected to the wrong plug in the firing order. I am going to trace the wires but I was looking for a pic of the wires on the distributor for firing order.

Firing order is 1 8 4 3 6 5 7 2. Typically the #1 wire is between the points window and the vacuum advance.

Edit: Looks like ml1955 has it covered.

There are links to Corvette wiring diagrams in the help
section near the bottom of this web page
( http://home.mchsi.com/~magicv8/index.html )
that show the wiring sequence and routing.
