What do I have to do to put a 95 Buick Century 3.1 into a 97 Chev Monte Carlo?

they have the same rpo and vin code, i would think at most you have to put some sensors from the 97 on.

So there won't be any problem then mounting the 95 Century motor to the 97 Monte Carlo tranny and the motor mounts work? Also, how do I know what sensors to change and does the wiring harness match up?

AQlso thank you very much for your time

ive never done a 3.1 swap so i dont know specifically, but normally if the are the same rpo and vin you just take the old engine out and compare. swap parts to the new engine as necessary. if they are different use the wire harness from the 97 and the sensors
