GALLERY: FACTORY SUPER SIX WAKES UP OUR 1967 DODGE DART

Well then either your motor was already toast, or you did something wrong.
Either way, I would not brag about it, perhaps you should post what you did on the supersix conversion with details on the results you got, someone here could help you get it running better.

Straight up stock install. I did get it running better; I put in a 360, but I'm not going to say that here because I don't want anyone to get butthurt.
