LT4 Pistons GM part numbers ?
Can somebody please tell me what the correct part numbers are for a 2017 - 2019 ZL1 with the supercharged LT4 650 HP engine.
I was given several different part numbers by 4 different Chevy dealers and Scoggins-Dickey, but these numbers show up as Discontinued or as being for a SS Camaro or CTS-V without supercharger ! 12690483 Left Discontinued 12690484 Right Discontinued 12661868 Left Camaro, CTS-V, Left Without supercharger 12669437 Right Camaro, CTS-V, Right Without supercharger Please help with the absolutely correct OEM LT4 piston part numbers

The dealers should've offered a superseded replacement number... Is there a reason why you don't go with an alternative, like Mahle or something? I think you can order a set of BTR-replacements, too. At least I've seen that for LT1s, but they likely work for LT4, too.
