I think you should look for a later 235. A lot of guys with '60s Impalas,Belairs,Biscaynes yank them to install V8's. Then they darn near give them away. I picked up a 235 from a '62 wagon w/89K miles for $30 recently. This weekend I'm getting one with supposedly 35K miles for $100. Soon I'll have 3 motors for each truck I own.
How far south in MO are you?
