you could unbolt the mounts and pull it out, just 4 cradle bolts and the whole assembly falls down, or bending down into the engine bay and fighting tight spots and hard corners to get the mounts undone. Your call really.

Either way the the main wiring most likely won't be different, but the engine harness you will want to transfer, and swap PCMs as well. tranny and blocks are basically the same so they will bolt straight up, shouldn't be too tough.

Good Luck
