Knocking noise from bellhousing

[SNSTR-TA]

Hey guys,recently got my 383 and B&M 4L60E put in..I have this knocking noise that increases with RPM's,isn't really too loud,but used a stethoscope and its definitely coming from the bellhousing..Was scared it was quiet rod knock at first but thankfully all you can hear when you listen at the oil pan is the oil pump..But was wondering if anyone would have any ideas as to what it may be? Im hoping its just loose flywheel or stall bolts,even tho they were locktite'd when we put it in..

I'd definitely check the flywheel for cracks and loose bolts.

Yea hopefully its not the flywheel since its a brand new TCI one lol..From what I could tell when I had light on it,it seems to be fine..Prob just gonna have to drop the tranny to diagnose and fix this either way..
