    Correct manifolds for 67S

    I noticed on this 67S motor for sale the tall manifolds. Are these correct for my motor, I have the normal short manifolds?

    Also, would this help with lower RPM throttle response, or is it simply a benifit for high RPM running?

    No they are not correct for factory delivered 67S they were 65MM tall. Tall=good for high RPM, it increases air velocity, not so good for low RPM.

    I have no problem with the theory that all men are created equal.
    But after that moment you are on your own and nobody owes you a damn thing.

    Manifolds (or at least one of them) are also date stamped so the correct one for a 67 S would not only have the correct port sizes but also the correct date stamps. Mine are stamped 66

    Not buying, just curious if they were correct. It sold on Ebay today for $5800 I believe.
