Reply to "Need a comparison between the C302b heads and Roush intake vs the Edelbrock aluminum heads and RPM Air Gap intake"

Yes, a331. I had one that had ports the size of 5.0 Ford ports and a raised plenum floor.

It was about seven pounds heavier than the a3 torker.

The 331 "came in" about 700 rpm lower than the standard torker which would hit in at about 4200rpm.

Dan Jones showed the torker second best to theHolley Track Dominator on iron 4v heads.

I dont know what it would do with any of Ford aluminum heads.

Many of the c3 heads I have seen on the bench come very close to the as cast a3s.
