No. Buick, Olds, Pontiac, and Cadillac are the same. Chevrolet is different.
Not really. Exterior dimensions are the same, and everything bolts on the same, but the bore is different which requires different pistons.
A 350 Oldsmobile engine has a different bolt pattern than the Chevrolet engine. The 350 Olds and 350 Pontiac engines have the same bolt pattern. The 350 Chevrolet and the 350 Buick engines have the same bolt pattern. Unless you have a dual bolt pattern transmission (there are some out there) in that Chevy, the Olds engine won't bolt into the Chevy transmission.

not if it is an Oldsmobile engine, Buick, Pontiac, and olds had the same bolt pattern in the 70's, different from Chevy
Yes if the 89 had the same size motor as the 95 the 95 motor will bolt right in. The Chevy 350 did not change from 88 to 95. In 96 it went to the vortec 350 its a little different.
