All the 235/261 pressure-lubed crankshafts are identical, so far as I know. The 1941-53 235 spray-oiler cranks have the same rod and main bearing diameters, but the #3 main bearing thrust faces are wider. A pressure-oiled 235 crank will fit a 216 block by machining the thrust faces for the wider bearing, but the 216 pistons would stick out of the top of the block 1/8" unless a shorter connecting rod or a custom piston is used.
