Camshaft ID
for the engraving i see 308/314
then R8-24488 BC
(the R might be a B or a 3)
i can't make out the stamping.
further info of what it came out of or any details: was it a hot rod motor? does it have high compression pistons, did the seller say it was a race motor? etc etc
i surmise that 308/314 could be duration, which racy...
