Yes, that is an LT1 block.

Camaro/Firebird/Corvette LT1's have aluminum heads.
Caprice/Impala have iron heads.

and iirc the cam was slightly different between the iron headed and aluminum headed blocks

The cam was slightly different but by all accounts the b-body one made better lowend and in bolton form they make similar peak numbers which would seem to suggest if anything the f-body cam was the one compromised. Maybe to keep your POS axle alive.
