Are you replacing all of that EGR stuff or just deleting it? I have a 3fe in my 40 and deleted it to simplify it a bit more. Your frame looks pretty bad. It looks like a good donor for your 40 IMHO although I don't like killing cruisers that still have life left in them. Not as bad when you are using the heart to keep another one on the road. 3fe is a great motor in a 40, totally different feeling with a manual transmission behind it as well.
