Interesting. All LT1 and LT4 engines are assembled in Tonawanda, New York for both 2016-present Camaro SS/ZL1 and 2014-2019 Corvette Stingray/Z06. The final assembly for all Camaros is East Lansing, Michigan and the Corvette assembly line is in Bowling Green, Kentucky.
So the question is, were these engines supposed to go into Corvettes but somehow made it into Camaros? Possible shipping/logistical error or error in applying that stamp on engines headed to East Lansing and not Bowling Green?
You could always call GM’s employee directory to find out where Ms. Carothers works lol

What has been discovered so far is that this plaque is placed on engines that were hand assembled by one person at the Corvette plant in Bowling Green Ky. This action was reserved for the the LS7 used in the Z28 and the LT4 and LT5 used in the Corvettes. Now some are showing up in the 2020 and possibly 2019 ZL1 and ZL1 1LEs. A source at GM allegedly stated that future engines installed in the ZL1 will be hand built by the Performance Build Center at Bowling Green. To the best of my knowledge I’m the first one to find a LT1 engine with this plaque installed on it. Very curious indeed, and also kind of cool.
I was also contacted by a C6 Corvette Zo6 owner who stated that his engine had one of these plaques on it. Interesting information but I am mainly interested in the 2020 year model Camaro.
To date a total of 3 other Camaro SS 1 LEs have responded that their cars have this plaque.
I appreciate your feedback and I am aware of what exactly each engine and suspension designation that was mentioned is.
