318 running rough and losing vacuum when in gear.

so my engine is a 1971 318. today I pulled the tranny (727) non-lock up. (Spline to the end of shaft). and the torque convert has weights on it. I searched the numbers on the converter (03193) only close thing I could find with that # is it may be for a magnum engine. anyways I think 318 torque converts do not have weights as they are internal balanced. this would explain the bad vibs . the bother inlaw I got the car from kept telling me the driveshaft was out of balance. with that convertor # can anyone tell me if it was a lockup converter.
thanks
