By Gold Crown do you mean the pavement car that was designed to run tracks bigger than a mile? If so, it's my opinion that the failed, extremely poorly thought out, experiment that was that morphodite vehicle, did more damage to the Silver Crown cars than anything else ever. Whoever came up with that idea should be permanently banned from motorsport! Trying to turn big cars into a Nascar support class was a terrible idea. Here's a fact that remains true, USAC racing, sprint, midgets, and crown, always have, and continues to produce the best racers in the world. Why anyone would want to try to change it is beyond me
