Can a 74 camaro exchange with 72 split bumper front clip?

No, a 1974 Camaro and a 1972 Camaro have significantly different front end designs. You can't directly swap a 1972 split bumper front clip onto a 1974 Camaro. The body structure, fenders, hood, grille, and core support are all different and incompatible. It would require extensive fabrication and custom work to even attempt such a swap, and it wouldn't be a simple bolt-on affair.
