It was originally a 330 bravo 1996 gen 6, but these are the only numbers on cam the first set it on the face the second is on shaft

Adam,
These are the specs for the cam provided it is the original 330 piece. That is reasonable given the GM # for the 330 is a 2296 cam and those markings appear on your core. You can pull enough data off one lobe with V-blocks and a dial indicator to validate.
