Typically, if it is a super duty, you'll find "455SD" decals on the shaker scoop. If yours is a high output or standard engine, it will be badged as simply 4 5 5. If you're still unsure, the super duty utilised round port cylinder heads and an LS2 intake. It also included cast iron exhaust header-manifolds.

Why is 1973 455 under rated what is the rating?
Which 455? Buick, Oldsmobile, Pontiac? The most powerful 1973 455 would be the Pontiac 455 Super Duty rated at 290hp @ 4000rpm. It was underrated, since factory stock examples were running 13.5-13.9 @ 103-107mph at the drags, which requires more than 290Hp. Car and Driver tested one with an automatic and it ran 13.751 @ 103.6 with a stock tires and a full tank of gas. The weight of a 1973 Pontiac Trans Am would require at least 350-375 hp to turn those numbers.
