common components between D4400 & D3400

Are there any common internal engine parts between a D3400 & D4400? I bought a running D4 2t engine that was pulled for a broken bellhousing and I was wondering if any of those engine parts would fit into a D2 5J or d3400? Would a d4400 engine bolt in to a 5j D2? Just curious. I might be interested in trading the whole engine for a d3400 if someone has one close to Ohio and is willing to trade.

There is very little if any major parts that are the same from a 3400 & 4400. The bores are different as the 3400 is 3 3/4" and the 4400 is a 4 1/4" bore and it goes on from there. The starting engines are basically the same so they can be swapped from one to the other with minor changes from one to the other.
