The Lincoln Y-block V8 engine was Ford's earliest OHV V8 engine, introduced by Lincoln in the 1952 model year.^[2] Like the later and better-known but even more short-lived Ford Y-block engine, its block's deep skirts gave the block the appearance of the letter Y from the front.^[3]

The Y-block's development was in response to the sales success of the competing Oldsmobile "Rocket" and Cadillac OHV V8 engines, introduced in the 1949 model year, the Buick "Nailhead" engine introduced in the 1953 model year, and the OHV V8 Chrysler Hemi engine in 1951. Also, Ford needed larger and more powerful truck engines. The basic engine design was produced through 1963.^[4] It was replaced by the newer MEL engine for car applications in 1958,^[2] and was replaced in heavy-duty truck applications by the FT (330/361/391) engines starting in 1964.
