Yes, it is unfortunate there are not better blocks available for some combinations, but that doesn't make it ok to accept an intake manifold that's was originally listed by Mopar as "the result of an extensive dynamometer and track development program" and "for your super stocker, formula car, or bracket racer."

why are you just limiting to one class, billy goes after the 273 manifold regularly. Even in this conversation.
