    Yes, but I think that the converter lock up is supposed to be manifold vacumm.

    When I put the 200 in my Olds, I have a vacumm switch that is connected to manifold vacumm. It is adjustable to allow the lock up at a speed that is comfortable.



    To answer your question though.........YES, the manifold port will run it all.
