Help with spark plug wire routing
Hi guys,
So im going to buy new sparkplug wires tomorrow, and want to know the correct way to route them so that they dont burn on my manifolds. Can anyone show me how to do this, or have a diagram i can look at?
Thanks!

The front wires need to go between your motor mounts.
There is specific shielding that mounts between the exhaust manifolds,
to the lower center of block, (2) clips (1) on each side of the oil pan for
the front wires, (2) brackets on both rear sides of block with wire
looms. The passenger side wires get tucked behind the starter and back
up to the cap. Check Paragon or Corvette Central for all the parts
mentioned above that you don't have.

Your best bet is to look in the A.I.M. There will be exploded diagrams showing individual shielding pieces to mounting hardware/locations. Different years had slightly different shielding.
If you're going to work on these cars it pays to spend a few bucks and get an A.I.M. I found that out myself this summer.
Good Luck

those pics do help. thanks guys i always know i can count on the forum. Here is a couple more questions for you guys.
1. I will probably be installing headers soon, so should i not buy any of the heat shields for my manifolds now? seems to me they are routed different.
2. What is the best brand of wires to buy? Niether Autozone nor Napa has AC delco...
3. In the pics from that other thread, there are these clips that hold the wires all together, where do you get these?
Thanks!

Typically with headers you will route the wires along the valve cover and the wires will be a different length than the originals. Most people with headers use performance wires from MSD, Accel, etc. and cut them to length for a nice appearance and use with aftermarket looms. Performance wire sets typically have a better core wire than OEM and thicker insulation to protect them from header heat. So if you purchase headers in the future you won't be using the lower shielding or the stock wires. You can still utilize the upper shielding with headers if you desire. Are you going to keep your car green?

thanks for the info. I am going to keep the car green acutally. One i dont have enough money for a new color, two its a driver quality paint job which is all i need now, and three the bright green color is the second least ordered color in 1975. Get compliments on it all the time

IMHO, if the motor is not original and you are not worried about keeping a stock look I'd get a set of wires that you can adjust the length. If you take your time you can custom cut each length and end up with a nice clean look like that pictured below. The stock wires are very long and route up and over and through the woods...it's a mess. I've also heard of guys doing tests on the stock length vs a custom length wire. The custom, i.e. shorter wires have less resistance - less path for spark to travel and therefore produce hotter fire at the plug.
