I just looked at Nitro Joe's stats, 62/65 competitors in D/SA have an aftermarket block listed available for their combo in the NHRA Accepted Products list (no Olds 455 or Buick 455 available, as far as I know). 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."
