While externally the '05 would fit in the '06 (same dimensions, bolt-up, etc), my understanding is the internals are different. In '06 they "redid" the engine internally, which means the 05 will not work for you. You can use the engine out of an 07, but you'd need to swap your '06 injectors into the other engine.
