The OP might have a very good reason for wanting to completely rebuild a 235. Not going to question those reasons, “wanting to” is a good enough reason. Just to offer an alternative….
You’re not going to trip over it one walking down the street like you would with SBC/ LS motors, but good running 235s with LOTS of live left in them…are out there. They were in so many GM cars and trucks over so many years, and so many people remove them for V8s.
If you’re patient enough and watch Marketplace, you can probably even find an example and go hear it run before the guy pulls it out of his 1962 Biscsyne or whatever. It doesn’t knock or smoke and has good compression…throw some gaskets and seals at it…paint it up real nice, and go have years of fun for less than $1000.
