I have a set of factory LW rods with aftermarket cast pistons I'd like to use. They are assembled with pressed pins. I wanted to upgrade the rods to factory HD rods that I have, so I brought them to the machine shop yesterday. The machinist says it can't be done because the HD rods I have are bushed for a floating pin.
The machinist says the aftermarket pistons I have aren't made for floating pins (lack of circlip groove), and that he can't press the brass pin bushing out and use the press pins either. Is this true and what needs to be done to use these HD rods with press pins/pistons?
