For the second generation of the Marquis, Mercury revised the powertrain line. Along with ending its Marauder branding for engines, Mercury replaced both the 390 and 428 FE-series engines with a 429-cubic inch 385-series V8. A short-stroke version of the Lincoln 460 V8, the Marquis offered the 429 with 2-barrel and 4-barrel carburetors (320 and 360 hp, respectively). The manual transmission was discontinued, paired solely with the 3-speed Ford C6 heavy-duty automatic. During the 1972 model year, the Marquis received the 460 from Lincoln as an option; for 1974, the 460 replaced the 429 outright.
