Interested here too.
Did you ream the bushing after installation for good fit on the new wrist pin? Check the alignment of the installed piston skirts against the deck of the motor (just to eliminate gross error or bent con rod)?
I'm not a very experience engine builder by most standards here, but I've always been astonished at how well these little bronze bushings have held up, with almost no wear over manyK in the puchs I've owned. (edited)
