And the 71 455 H.O., which came in all 1971 Judges and all 1971-1972 Trans Am's (optional in the 71/72 GTO, and optional in the Formulas) was definitely not a station wagon engine. It was one of the best engines of the 1971-1972 era. Many people confuse the 1971-1972 455 H.O. engines, which had round port heads and an aluminum intake (basically a low compression version of a RAIV 455) with the 1970 455 H.O., which, unfortunately, was just a basic D-port engine 455 with a standard steel intake. In 1970, the 455 H.O. was basically the 400 H.O., with extra cubes. In 1971, the 455 H.O. was a true high performance engine with many unique parts.
