Ross will probably have some first hand experience and suggestions but offhand I can think of a couple of things. You didn't mention year or say if the converter is tight to the flex plate but that is one place to look. If a 50 or 51, the earlier converters had drain plugs in the front face and had to have a flex plate with access holes drilled accordingly. That could a reason for the gap. Another is if the converter hub or reaction shaft hub has not engaged the splines in the front pump area so converter isn't totally seated in trans.
