I am replacing the w16y that it’s currently running and hoping for a little more power. Based on the online pictures I expected the electrodes to be longer. I attached 2 pics one of what I expected and the short one is what I received. Are these correct? Thanks Attached Images Last edited by pondr; 04/30/23 04:35 PM.

I run those plugs in both '28 engines that are in my two trucks. If memory serves me correctly, I set the plug gap at .035" and the point gap at .018". Correct distributor timing is crucial.
