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.
Merc# 431-850453T / GM#12552296
.004” 280º/299º
.006” 266º/284º

.200” 113º/114º
Lift .480”/. 483”
ICL 115.5º
ECL 120.5º
LSA 118º
