con rods for sst60 are same as 70hp bridgeport. part number 394462 same length no different.
piston no for sst60 and 70hp bridgeport part no 394461 same pistons.
crankshaft for sst60 is what was used on 65, 70, 75 hp to 1986 (after that fishing motors went to multi spline) part number 328788 same throw 4 splines.
these are all omc specs and part numbers.
so no idea where the myth of the long rods and longer throw cranks come from.
I do know that is what fast fred would use in a special mod 50, but not what omc used for the sst60 motor.
