For the decoding masters!!

I have a 454 with C6117775 as a serial number.. block is a 3619595 which is common and the intake is common also.. what gets me is the exhaust ## come back as a police issue #?
353030 and 3994045 so it has me wondering if it was a police engine. Any help would be appreciated, I just never have any luck with the codes on the front of the block.
built 1-26-75
numbers on front machine pad are C6117775
Thanks
