TPI 350ci spark plugs,help
Today I opened #1 spark plug and I noticed that half of the thread is black and the electrode is white(its platinum and .750" reach) and Im worried about it,My Camaro got MSD 6A,MSD wires and MSD coil and I want to know what causing the black carbon on half of the thread and the white thing on electrode and what reach is the stock spark plugs for TPI 92 Camaro iron heads?

So now I cant use the car till I change the spark plugs right? but how is that the previous owner was using long thread plugs and nothing happend? when I changed the spark plugs to platinum I toke the part number and I went to auto shop and bought Platinum plugs and when I changed the plugs installed MSD wires coil and 6A I just felt a little difference but nothing in performance are long threaded plugs cause this? because my friend got a 91 Z28 with the same set up but a stock camaro hes kinda faster and we both run healthy engines
