As you probably know the 261 engine is a popular size in demand. I would add up all your cost for machining and replacement parts,and some for your own labor. 261s can run from a $500 or lessfor a reduildable core to a multi thousand dollar complete rebuild and/or modification. If you really want a 235, I would post an ad in Stovebolt and see if someone has a comparable even trade value wise with a little cash thrown in with the 235.
