Looking for info on 2406782 rods

I found a group of 13 part #2406782 rods for sale cheap locally, the guy has them listed as 273 rods. They appear to have bushings in them which tells me they should be floating pin. What’s the difference between these and floating pin 340 rods? I’m looking to upgrade a 360 with floating pin rods so I can put some KB Hypereutectic flat top pistons in and bump up the compression. Would these work for that or is the pin a different size? Thanks for any help with this you can give.
