Will an Oldsmobile 350 engine fit into 1989 blazer?
The Oldsmobile 350 engine has a different bolt pattern than the engine that comes in the 1989 Blazer. This means that the engine would not be able to be bolted in without modifications. Also, the Oldsmobile 350 engine is a rear-wheel-drive engine, while the 1989 Blazer is a four-wheel-drive vehicle. This would mean that the transmission and other driveline components would also need to be changed in order to fit the Oldsmobile 350 engine into the Blazer.
