No, unleaded fuel is
not good for a Cadillac 472 engine. The Cadillac 472, produced from 1968-1970, was designed to run on leaded gasoline. Using unleaded fuel will likely cause damage to the valve seats, leading to premature wear and potential engine failure. These engines need the lead in the gasoline to lubricate the valve seats.
You'll need to use leaded gasoline or a leaded gasoline additive specifically designed for older engines. Consult a mechanic specializing in classic cars before attempting this; they can advise you on the best course of action.
