Fifty + years ago, the only thing I ran in several "go-fast" Chevies was Champs. As time went-on, the Champs became more and more prone to fouling. Later in the early '80s and to this day, I had some STOCK, factory hi-horsepower Corvettes that were all impossible to keep Champs running clean in. Changed to Factory-type AC plugs and the little Chevies love 'em. I've had the same bad results with Champs in my flatheads. Only Autolites for me any more. I know that "Kiwi" is gonna hate me for chastising his Champions. Just my experience! DD
