I was reading in a book about nitrous, and they were talking about spark plugs. Obviously to use a colder plug, like the TR6 for us, but it also was talking about shortened negative electrodes to prevent electrodes from heating up and acting like glow plugs, causing detonation. Picture showed electrode not even extending to middle of plug. I was wondering if any one has cut, and shortened electrodes? And what were the effects?

the shoter electrode is good because it moves it away from the center of the chamber where most of the heat is. This helps is preventing the tip from becoming a glow plug.

Have you or have you heard of anyone cutting the electrodes, on like TR6's. Or do you buy plugs that have short electrodes.

Autolite has a series of plugs called the AR series. They have shortened ground straps and work great for nitrous. I use them in my mustang, you'd have to see if they have the AR version of the autolite 103's which are 1 heat range colder standard LS1 plugs.
