Connecting rod ?

Can the stock rods be used with full floating wrist pin pistons without being bushed? I got a set of floating 4.8 pistons for the 5.3 and wondering if the rods need work or if the wrist pins are the same size and will work.

Stock rods are not floating. The Pin diameter on the stock rod is .943, after-market rods are .927

I believe the 4.8 pistons are off one of the newer 4.8 like 08 09 10 and I have a 2005 5.3 going by what the junkyard had it tagged. The 4.8 pistons are definitely floating just not sure if the rods in my '05 5.3 are or not. I believe they changed to floating wrist pins in the '05 and up 5.3 just trying to get some clarification.
