I'll put money that no iron d-port will keep up with a set of properly done alum d-ports. I don't think Jim's test was a fair test. Jim was heavily vested in iron, he didn't want the alum heads to out perform the iron.

About Us

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
