Good morning. My son (who is 17) just picked up a 1940 Chevy with what I believe is a 216 Stovebolt to restore. (So happy the young kids are getting into these cars). The casting numbers are 839132 and the stamped numbers on the side of the block left of the distributor are 226930. From everything I have researched and the 2 bolts that hold down the value cover indicates it is a 216 but a friend insists that it is a 235. Can anyone verify what it is from the photos? Also we have the opportunity to pick up a running 250 AND 230 with an automatic transmission. We are thinking of doing a swap because they are more improved engines but wanted to hear other people's opinions.

Any information would be helpful.
