Magnum mount issue?

It wasn't balanced at all not neutral or zero or internal It was left as Ma' Mopar made all 360's. They goofed and assumed it was but the engine was for the guys own truck project and he had no intentions of doing any balance on it he offered the short block to me and built to spec from there and everyone assumed it was balanced but it was built for soem time and as things happen in life people forgot etc so it sorta snowballed. Its an hones tmsitake and I get a new Dynamic convertor out of the deal a bit of hassle but hey.
