I have one of these converted splash 235s running in my 47 coupe. Has a later full pressure crank, and it takes some machine work to the old block to accept the later crank plus mods to oil passages. However the downside it's a low compression motor only about 6.5 to one plus milling the head on this motor is very expensive as you need to sink in intake valves etc etc.
As stated by the guys above the pressure 235s and 261s are an easy swap. I'm thinking about making the leap to the more modern 250/292 in my old flatbed, with an automatic behind, SWEET!
