Basicly the same design, Yes, The crankshafts do not interchange though since the 455 has 3.25" main journals and the 400 has 3.00" mains. Heads, intakes, cams, oil pans, oil pumps, distributors, ect all interchange though. 400 is 4.12 bore 3.75 stroke 455 is 4.15 bore 4.21 stroke

No such engine as a Pontiac 400 Big Block. The back of the Pontiac engine block has a different bell-housing bolt pattern than the Chevrolet. Pontiac and Olds bell-housing bolt pattern match. Chevrolet and Buick match. Unless you have a dual bolt pattern transmission (GM did make them) the Pontiac engine won't bolt up to the the Chevrolet transmission.
