Identifying bushed and press fit pistons

I have two sets of connecting rods both out of 318's
Both the 318 rod have casting numbers 3418645
Trying to determine if they are press fit or floating.
One set has a retainer clip? The other does not.

Please note the picture with 2:sets of rods and pistons 1 is the 318 with the retainer clip (3418645) the other is a 273 rod and piston (2406782) also with the retainer clip. I am hoping/assuming the retainer clip ones are floating?
