Don't ovelook Patrick's as a place to check out for any engine swap from 216 to 235. I don't have the web site book marked, but try
http://www.dogpile.com and plug in their name in the fetch area. Dogpile is a good search engine and will locate Patrick's web site easily. I have a '42 coupe that has been modified. Having done so, I would love to have been able to return it to original and start on her again as a complete restoration. I yanked the 216 and gave her away quite a while back. The engine was full of crud and would have not been a good bet on a rebuild though.
good luck on her,
Huey
