Thanks for the replies guys but those plugs your suggesting are all .460 reach plugs...I need a plug w/ .750 reach or it doesn't make it to the combustion chamber. I've been cross refrencing these w/ sparkplugs.com. Any other ideas....can I just get a plug with that reach? Talking to the local parts counter "fools" is frustrating if you don't have a part # I'm sure you have all dealt w/ them before. They only know what the computer tells them.
