The block stamping (DRL) was assigned to 1979 350/170 hp 4B, AT, CE  in FS passenger and Camaro...
CE means California Emissions; your VIn indicates LA assembly for a 1979 Camaro or passenger car.  The 2 bolt mains and '010' block is consistent with that.  I'd guess the pink rods (assuming you mean HD rods) were installed when the engine was rebuilt.

I'm what is referred to as 'car poor', Blackthunder..

Welcome to CRG...  it would be good if you introduced yourself to the group, tell us a bit about you and your Camaro(s)...   Where are you located?
