full floating wristpins vs. pressed wristpins

Depends on your meaning of "converting". That is a replacement bushing for a rod which originally was prepped to have a bushing, Unless you intend on resizing the small end of the rod to accept a bushing. That's a lot of metal to take out! That wouldn't thrill me if I was asked to do this!

The rods are the same, whether bushed or pressed. At least with Mopar. That's all the factory did. They just honed the small end to accept a bushing. There's plenty of meat there to do it. People have been doing it for decades with no ill effects. It won't hurt a thing.
