So, what do we have?
Knowing the Norwood plant built Chevrolet Bel Air, Biscayne, Impala, Nova, Caprice, Camaro, Pontiac Firebird, and the Buick Apollo.
From 1972 - 1974, the primary output was the Nova and Camaro.
We can deduce your engine is most probably a 350 cid, 295 HP, 4 bolt main, from a 1974 Camaro or Nova.
