I speak "machinist"- - - - -they're going to tell you it's "junk" which translates to "Even if it was in brand new condition, we don't know how to work on it!"
Depending on the year, the 235 might be a drop-in swap, or there might be some issues with the position of the water pump and fan. The simplest 235 swap will be a 1954 or early 55 engine. In mid-year 55, they dropped the fan and water pump down on the block about 3 inches for hood clearance, which puts the fan too low on the earlier trucks. There is a conversion plate available to reposition the pump to the higher position when installing a late model engine in an early chassis.
