Hope you are talking about 2 juniors or 2 seniors. A junior and a senior will result in problems.

In addition to the engine and trans you will want to change the rear axle to get the correct gear ratio. Junior and Seniors had different rear axles driveshafts and wheels.

You will also need to swap out the steering column gearshift and the pedals.

It's a big job but an expert mechanic should be able to do it for a few thousand $$$$ bucks provided he has both cars sitting side by side.
