I don't know the last year it was actually possible to hand crank a Chevy truck with the radiator in place; 1950 maybe. I know my 50 3600 with the original... everything has a notch in the bottom center of the radiator for crank clearance. Here's a good
discussion from awhile back with a link to Denny's pictures of the crank and bracket. Like you I suppose the grille and HB/pulley are carryovers.
If you ever visit youtube there are a few vidoes of hand cranking 216's. In fact there are lots of 216 Chevy stuff on there.
