REDEEMING THE FORGOTTEN Y-BLOCK
When Ford introduced its Y-block engine in 1954, it labeled the engine the worthy successor to the venerable Flathead. The Flathead gained a loyal following of hot rodders and racers, but the big Cadillac overhead-valve V-8 and Oldsmobile’s Rocket 88 were stealing Ford’s thunder in terms of power, so something had to be done, and Ford decided to respond. The answer was a clean-sheet V-8 design, featuring overhead valves and improved cooling compared to the old Flathead. It was dubbed the “Y-block” because of the way it looked and because of its deep skirt and tall cylinder heads.

LS is MORE
When GM introduced the Gen III small block in the F-body, it rekindled a dying performance flame with its new-generation small block. While the Gen I small block actually kick-started the hobby and got it into gear, it’s the latest family of small-block engines that has grabbed the attention of enthusiasts everywhere—and for good reason.
