Don and Doug,
The deck height of the 221, 260 289 and 302 were all the same
at 8.205 inches. The rods of the 221, 260 and 289 were 5.155 inches.
The Rod for the 302 is 5.090 inches. The Compression height of the
pistons for 221 260, 289 and 302 is 1.600 inches. Therefore if one could
use 260 pistons on 302 rods, then the 302 crank would work. Not sure
about the piston pin dia. Don, if you are going to do this then suggest
that you bore your block about 30 thousands and use new oversized
260 pistons.
Boss 302 rods are long 5.090 with a 1.529 compression height on the pistons.
