Another Olds :tup:
BTW the Buick and Olds 455 are differnet as well as the Pontiac.
Olds' are underrsquare with a 4.12 bore and 4.25 stroke.
Pontiacs have the 4.21" stroke mentioned and Buicks are 3.9" :eek:
Of course rev potential is more than the stroke but either way high RPM in an Olds it about 4500 (:
