Block ID 481988 A275 Code stamped RR


Question

Hey there ,I have searched forms and goggled it almost there with this I think.  Lots of good info however I’ve hit a wall with the block code
block has

cast  A275 date code and 75 beside The distributor so defiantly a “75”

as far as the code goes and stamps on passenger side front doesn’t check out. 
seemingly random stuff ? 
Please see photo attached. 
Stamped RR passenger side top near head. 
under that PB 8091 stamped. 
cast YU and I think 537. 

Any clarification would be awesome 

cheers Doug
