Well I got up early Sun. morning, my only day off for the last 3 months. And I turned the TV station to speed channel. American Muscle Car was on and they did a dyno piece on the 60s muscle car engines. Did anyone catch this? It was real entertaining and very informative. i can say that I was quite shocked to see the results. They dynoed all the engines just like they were produced with the exception of a good blue printing and gasket matching. But other than that, they were factory stock. First to be tested was the famous 409 rated by the factory at 409 HP. It produced 406 HP at the crank. Not bad. then they tested the 421 superduty pontiac rated at 380? i can't really remember all the #s. but it dynoed at 420??? Again not too shabby. Then they dynoed the infamous Ford 427 rated at 425. And wow did that blow my mind. 637 HP I believe or close to that. But just WOW! Unbelievable!!! I thought that the gaunlet had been laid. Then the most famous street engine of all lore made its appearance.
