How? I haven't seen these specific pistons, but all of the aftermarket pistons I've seen so far have sone kind of oil passages either in the pin boss or in the oil ring groove.

I actually just finished building a 346ci LS1 where we used the press fit rods from a 2001 Corvette and a Wiseco piston with a .927" pin, honed out to .945". The engine is already in the car and has run for a little bit, but we'll get some more miles on the thing and see how it works out.

I thought the bushings were there for a reason. Not that I am saying it wont work. They do oil like you say. Why even bush the rod though then? Just a thought.

The pin is still pressed into the rod so it doesn't need the bushing or the locks. I've heard of shops running a floating pin without a bushing, just steel-on-steel, but I wouldn't ever do that. Similar metals rubbing against each other is supposed to be a bad thing, so I think that's the reason for the bronze bushings.

Ah. Well from what he described, the pin was not pressed in. That is what I got from him. In that case, I would look for a machine shop to bush it. Or a new set of rods like he is.
