    Hello All,
    Does anyone have an OEM GM427 piston from a 66-69 engine? The GM part number is 3876884. I need (1) so any help would be appreciated, thanks!!

    Have you tried going through napa or one of those outfits? Or do you have to buy the whole set?

    Hi Nancy,
    Yes I tried this. I am being told that I am going to need to find someone that had a 427 rebuilt and kept the old pistons. Thanks.

    I would not recommend taking a well used piston out of someone elses motor and trying to use it in yours, that's a recipe for disaster. Contact any of the specialty piston manufacturers, Race-Tec, Ross, J&E, etc, and ask them to make you up a single piston to the 66-69 Chevy specs and your finished bore size.

    Cheers, Mark
