Yes, a 5.3 can replace a 5.7 in a 1999 Chevrolet Suburban, but it may require some modifications. The engine mounts, wiring harness, and computer (ECM) may need to be adjusted or replaced for compatibility. Additionally, you should ensure that the transmission and other components are compatible with the new engine. Always consult a professional mechanic for the best results.
