Can a 1989 Corvette engine fit into 1992 Camaro?

No, a 1989 Corvette engine won't directly fit into a 1992 Camaro without significant modifications. While both are GM vehicles, the engine bays and mounting points are different enough to require substantial custom fabrication. The 1989 Corvette likely had a transverse-mounted engine (depending on the specific Corvette model), while the 1992 Camaro had a longitudinally-mounted engine. Even if the engine orientation were compatible (which it's not likely to be without significant alterations), the size and placement of components like the transmission, exhaust, and accessories wouldn't align. You'd need extensive custom work to make it even remotely feasible, and the cost would far exceed simply installing a more compatible engine.
