I am not sure what your question is but the term rocket really has no meaning in relation to any specific olds v8-it just means that it is not a flathead motor. olds and Cadillac introduced the first engines in cars that were not flathead engines in 1949 and Oldsmobile needed a new catchy name for their new engine-since engines at that time had no (rocker arms) for valve trane this was something new and someone decided to call the engine rocket. as far as the 72 455 goes they had anywhere from 225 bhp to 300 bhp depending on application. the bore is 4.13" and stroke is 4.25" and should only have a 8 to 1 compression ratio with low compression pistons-olds determined compression ratio with dish in pistons not cylinder head-although D cast heads had a smaller combustion chamber than the rest
The Rocket 350 oldsmobile engines will bolt in as well as the Rocket 455 olds.
In 1979 Pontiac did not make available any 455 (cubic inch) engine. The largest available was a 400 4bbl in the Pontiac Trans Am (220 net horsepower). Also the "rocket engine" description was only applicable to the Oldsmobile Division. The 455 Rocket Engine (Oldsmobile) was discontinued in 1977 where the largest engine was the 403 cubic inch Rocket Engine V8 rated at 185 net horsepower available on the 98 (a 350 cubic inch was standard) and the Toronado. It was also sold to the Buick division and available on the Riviera.

Yes i Don't know how many Oldsmobile Cutlass 455 were made but it wasn't as many as the Oldsmobile 350 Rocket. So it was a big plus if you had the 455 engine because it wasn't as many around.
Oil filter location should be on passenger side rear of block
Internal mounted between the engine and transmission.
According to Chilton's 1971 455 is 12btdc, but there should be a decal under the hood or even on the engine itself that would list this info.
350,400 or 455
at least 365
225 / 250 / 270 / 300 horsepower ( 4 versions of the Oldsmobile 455 - 4 barrel carburetor - listed in 1972 )
Oldsmobile stopped production of the 455 in 1976. There were no 455s produced in 1987.
The 455 will fit. The transmission might have a shorter tailshaft, though.
