THE only reason why Pontiacs are not the dominate force right now is because Duntov was stolen to work for Chevrolet. Cadillac had their own structure. There engines were much stronger than everybodys. This is proven over and over again in over 100 years of hotrods. The real truth didn't come out until the late "50's. Yes, a lot of guys ran Olds back then. But Olds was the test and refinement for Cadillac.
