Here's a few pictures of the block machining fixture I'm in the process of building to narrow the main bearing web on a 216 to accept 235 mains. That will avoid the necessity to modify the 235 crankshaft, and will also make it possible to use the later model 235 main bearings in the 216 block. The early (54/55) 235 mains are getting extremely scarce and expensive. The fixture will be turned by adapting a piece of hex shaft to the end of the mandrel, standing the block up on the base of a floor mount drill press, and turning the cutter at very slow speed. Depth of cut will be set by using a shaft collar to limit the downstroke of the mandrel. Any "machinist" who claims he can't do something like that needs to turn in his man card! Jerry
