Important if you run D-H/S or SA

The GMs and Fords benefit from them greatly as far as adding more power and the Chevy guys can buy them all day long for half of what it cost to get on the 3 year waiting list for a Chrysler block that they may never get.

Hi Paul, You're right, I've heard the horror stories but to quote David Lee, "it is not my problem".

Then, you have no argument against the manifolds,

Again David, I'm missing your point.

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."

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

This thread is discussing an intake manifold that is run in classes D-H.

If you're really concerned about an aftermarket block, make one or get one made, submit it to NHRA. You can do that if you really wanted to. I cannot make a manifold or get one made and have NHRA accept it.
