Default Spark Plug Wire Size
Currently rolling with some 7mm spark plug wires in my 69. Got gifted a new set of 8mm wires and was wondering if they’ll work. Thanks!

8mm will not fit your stock wire looms if you're still running those.

I run 8.5's on my 69 through all the stock shielding's with no issues. I do however have after market Valve cover holders.

Exactly what benefit will you be getting versus the labor in replacing them?
Are they both some type of spiral core wire as opposed to solid copper?
What has been done to the rest of your ignition system, in particular the cap, rotor and coil?
