    They were. 28oz is the old 302/289 and all 351. 50oz is the 82ish and newer 302.

    I thought I heard here somewhere that the 351w's were 28 oz imbalance like the pre '82 302s. Someone correct me if I'm wrong.

    this is correct... all 289's, pre '82ish 302's and all 351W's share the 28 oz. imbalance

    The first two years of production the 289 used a different imbalance - I don't remember off the top of my head but I remember the early C4s had a special balance on the flex plates that is not compatible with the 70 Maverick.
