Ever wondered why modern cars sound so much smoother than those old classics? It’s all about the lifters! Back in the day, engines used solid lifters, but they were noisy and needed constant adjusting. Cadillac changed the game in the ‘30s with hydraulic lifters—self-adjusting, quieter, and way less maintenance. Soon, everyone followed. Now, only a few performance cars keep the old-school solid lifters for high RPMs. Wild how one engine upgrade changed everything! #Cars #CarOwnership #CarHistory
