Re: need help chevy small block
I think that's a Pontiac prefix,as they did use that block too.
It would decode as:
K=McKinnon Industries engine plant
04=April
24=day
CBC=1972 Firebird code
N=Norwood assembly plant
600758=758th unit produced at Norwood,they started at 600001.
I'm not up on the Pontiacs much.
What's the complete block casting date on the back lip?
I realize this may not be correct as a 1972 Firebird used a 250 CID V6 for CBC callout.
Are you certain about the CBC prefix?
