"Different strokes for different folks"! The only reason I can think of to use a 216 is to go back to a bone-stock configuration on a restoration job. That pretty much limits its use to 1953 and earlier trucks. An 85-HP engine with 6:1 compression will definitely cure your detonation problems, though! I hope you're good at adjusting Babbit connecting rod bearing clearances- - - -it's a regular chore on those engines.
