History of the Oldsmobile Rocket 455 V8
A larger big-block was introduced for 1968 as the Rocket 455 at 455 in?? (7.5 L) to replace the 425s. It kept the 425's 4.126 in (104.8 mm) bore and bumped the stroke to 4.25 in (107.9 mm). 1968-1969 455s were painted red, while 1970-1976 versions were metallic blue. The "Rocket" name disappeared from the air cleaner identification decal after 1974. Although production of the 455 ended in 1976, a small number were produced through 1978 for power equipment use. Output ranged from 210 to 400 hp (156 to 298 kW).

The Rock 455 was used in the following vehicles:

  • Oldsmobile Cutlass
  • Oldsmobile Vista Cruiser
  • Oldsmobile 442
  • Oldsmobile Delta 88
  • Oldsmobile 98
  • 1968-1970 Oldsmobile Toronado, 375 hp
  • 1968-1970 Oldsmobile Toronado GT (W34), 400 hp
