Well, the tranny modulater, requires manifold vaccuum, to make the trans shift. So, a runner on the intake, or the carb BASE PLATE. Now, if you have a vaccuum line, you probably have a TH350. If the oil pan on it is shaped like an square, with a notch cut out of one of the corners, it is a TH350. 400's, do not require vaccuum.
