92 spark plug wires 7mm?
I have a 1992 lt1 and I bought it running rough. i changed the opti in it and also the fp regulator. i noticed the wires on it are 7mm ac delco(look fairly new). could this be a problem with it not running 100%? what is the stock size?

As long as there in good condition and the engine is stock, they are fine. 7mm has been on both cars I bought new from GM.
Look for a vaccuum leak, that seems to be a common problem on vettes.
If the last tuneup was over 50k miles, might want to put fresh plugs in and check the filter and PCV.
Easy way to check plug wires, is to find a dark place and open the hood and watch for arcing.
