Good morning,
The long blocks are the same but there are differences with the intake and exhaust manifolds.
You will need to strip down the donor motor to a long block and change over the external components from your engine to the donor motor before installing it in the car.
The motor must be exact when you install it to be sure everything will hook up properly and perform as intended.
