Over the years other displacements were added. The Olds 455 was introduced in 1968, it was developed from the Olds 425, which was a tall-deck version of the 330 engine design.

The bore centers are the same, the only differences between the short deck and tall deck Olds blocks are the deck height (9.33" and 10.625", respectively) and the main journal size (2.5" and 3.0", respectively); the diesel 350 used the BB size mains, however. All short deck blocks have a 3.385" stroke; the displacement varied by increasing the bore size. |
