Hey Dave, I wished I say your post a couple of days ago. There's a 216 in an old welder nearby. As far as a 235 crank going into a 216, I'm not 100% positive but I tink the 235 is longer in length than the 216 block would accomodate. The guys phone number for the 216 if he still has it is 541-826-5117. Thats here in southern Oregon. I tried to turn the engine with my hands and the belt broke but it started to move so I think it is not froze up. H.
