 The Lincoln-Zephyr V12 would quickly replace the previous-generation V12, just as the Lincoln-Zephyr car replaced the rest of the Lincoln line, and would be the company's primary engine through 1948.Similar in design to the 90° Ford flathead V8 introduced for 1932, the Lincoln-Zephyr H Series V-12 had a narrower 75° between cylinder banks.The engine used aluminum-alloy heads and cast-steel pistons, as well as two water pumps.
