1951 250 strange noise from bell housing

We have a 1951 250 2 door coupe with a 288 and Ultramatic. The 288 was rebuilt by a reputable shop in town and the ultramatic was rebuilt by another reputable transmission shop. Both work very well but there is this ongoing issue with a noise that almost sounds like a hung up starter bendix at times just contacting the ring gear. The starter has been out many times, checked, new proper p/n bendix reinstalled. Starter works great but noise persists. Not always there on start up but can be made to appear by making the engine work as in accelerating on highway. And then when backing off the throttle it will usually go away. It is not a grinding noise but more like a piece of tin hitting the ring gear although I don't know if that is the case. Very aggravating. Wondering if something was missed when the engine and transmission were mated and something is moving (torque converter?). If nothing else I am going to pull the transmission and take a look later this fall.
