Did general motors ever put a Corvette lt1 engine into camaro?

No, General Motors never put a Corvette LT1 engine into a Camaro *directly from the factory*. While both the Camaro and Corvette shared GM's LT1 engine family, the specific LT1 engines used in each car were different and not interchangeable without significant modification. The engine management systems, mounts, and other components were unique to each vehicle.
