Say u had a convertor/ flexplate from a 727 torqueflite that had run behind a steel crank 340, and u replaced your 340 with a 360. Now the 360 " bolts up"to the tranny just fine , but the balance is off because the 360s had cast externally balanced cranks. My guess is the shop wuld have to add a little weight to the convertor. Thye do it by welding on little chunks of metal, kind of like when u have your tires balanced neal Zimmerman, Eugene oregon [AD removed for archives] ------------------------------------------------------------------- Erase wrinkles without painful injections with Nexiderm SP.
