was introduced as an option; four-wheel disc brakes became an option for 1975. Powertrain 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. As the 1970s progressed, Mercury began efforts to improve emissions and fuel economy of its full-size range; following the discontinuation of the Monterey and the introduction of the Grand Marquis, smaller-displacement Ford 335 engines replaced the 460 as the standard engine offering. For 1975, the 402 cubic-inch Ford 400 V8 was introduced (largely as a successor to the 429), with the 351 cubic-inch Ford 351M V8 becoming the standard engine for the Marquis in 1978. In California and for "high-altitude" use, the 400 remained standard equipment; regardless of usage, the 460 (standard on the Marquis Brougham and Grand Marquis through 1977) remained available as an option until the end of the generation. The C6 transmission remained paired to the 460, with the 400 and 351M using the lighter-duty FMX transmission. Body design The second-generation Marquis was expanded from the previous two-door hardtop to a full range of body styles, inheriting the four-door hardtop from the Brougham and four-door sedan and two-door convertible from the Park Lane series. Under the 1969 rebranding of Ford and Mercury station wagons, the Colony Park station wagon became part of the Marquis line. For 1969 and 1970, the Mercury Marauder made its return, unofficially replacing the S-55. Designed as a competitor for the Oldsmobile Toronado and Buick Riviera, the Marauder was a fastback coupe combining the front bodywork of the Marquis with the roofline of the Ford XL/Ford Galaxie 500 SportsRoof.; along with the Colony Park, the Marauder was built on the 121-inch wheelbase used by Ford. During its production, the second generation underwent two updates, including a 1971 mid-cycle revision of the exterior and interior. In 1973, to coincide with the addition with 5-mph bumpers, the exterior and interior underwent a complete redesign, with the
