Thumbs down weird noises from the LT1

My 97 Firebird Formula with 120k miles started making a funny noise today.

the noise is like a belt squeaking, but it is coming from the back of the engine like where the engine mates to the tranny.

my dad thinks its a bearing because it speeds up or slows down with the revs.

has anyone had a problem like this?

any help is appreciated thank you.
