1970 The CJ model was dropped from the Cyclone lineup, and applied to some of the engine names in the series. Mercury thus featured the Cyclone, Cyclone Spoiler and Cyclone GT. The Cyclones consisted of 351 cid V8s and 429 cid V8 engines. The standard engine for the base Cyclone was the four-barrel with dual exhaust that was rated at SAE gross ( net). It was the standard engine in the 1970
Mercury Marauder X-100 and was available in other full-size models. It featured a 575 CFM carburetor. Two optional engines were available for the Cyclone. The 429 Cobra Jet was the four-barrel with dual exhaust but without the Ram Air induction. It was rated at SAE gross ( net) and had a 720 CFM Rochester Quadrajet 4 BBL carburetor. The 429 Super Cobra Jet, which was part of a Drag Pack option, was a four-barrel with dual exhaust and Ram Air induction, but it was rated at SAE gross ( net), and had a 780 CFM Holley 4 BBL carburetor.
1970 Cyclone Spoiler The Cyclone Spoiler was for the performance-minded with front and rear spoilers, black or white racing stripes that went from front to the rear of the car, an integrated functional hood scoop for ram air induction, 140 mph speedometer with a four-gauge suite including an 8,000 rpm tachometer with adjustable red line, vinyl bucket seats, dual racing mirrors and a competition suspension package. The 429 Cobra Jet with Ram Air was the standard engine for the Cyclone Spoiler, with the 429 Super Cobra Jet with Drag Pak and Super Drag Pak optional. The Super Cobra Jet upgraded the block to four main bolts and provided a mechanical flat-tappet camshaft, and the carburetor was changed from a 720 cfm Rochester QuadraJet to a 780 cfm Holley. Standard with the SCJ was the Drag Pack, this package added a front-mounted engine oil cooler and a 3.91 ratio gear, while the Super Drag Pack offered a 4.30 ratio gear and a Detroit "no spin" locker differential. Colors for the Spoiler were limited to Competition Yellow, Competition Blue, pastel blue, Competition Gold, Competition Green and Competition Orange but for a premium Ford included the 'color of your dreams' program, and 31 buyers took advantage. Ford had intended to continue the Spoiler II option for 1970 with an even more aggressive nose profile. One prototype was built.
1970 Cyclone GT For the sporting gentleman that placed more emphasis in style than speed, there was the Cyclone GT. The basic package offered comfort weave bucket seats, full-length console, twin racing mirrors, integrated hood scoop that could be made functional for optional ram air induction, hide-away headlights, three pod tail lights and unique lower-body line trim. The cost of all of this style was the having a small block 351 Cleveland with 2-barrel carburetor and a three-speed manual transmission as standard fare. However, there were options, and they were good ones. The 4-barrel version of the Cleveland small block followed by a set of 429 CID big blocks up to the Super Cobra Jet and the Drag Pak plus a four-speed transmission and a selection of automatics. Although early sales literature shows the BOSS 429 as an option, none were actually built. An oddity with the GT was the Action Special Equipment Package, for which 953 buyers pulled the trigger. The package included deluxe wheel covers, white sidewall tires, a vinyl roof, and most notably a bench seat replacing the standard bucket seats, all for about a $15.60 credit.
1971 For 1971 the Cyclone was marketed as the
Mercury Montego Cyclone. It had some minor styling updates; most noticeable was center section of the grill received a larger ring in the gun sight with the GT receiving a unique badge. The Spoiler received a revised stripe package, and the rear spoiler was painted flat black, and the Base Cyclone now had the integrated hood scoop like the GT and Spoiler. Under the hood things were different as well. Gone was the Super Cobra Jet and Drag Pak options, and the base engine for the Base and Spoiler became the M code 351 Cleveland with 4-barrel carburetor. For the Spoiler, Ram Air also became option as opposed to part of the package for 1970. Beyond minor changes in the color palette and available options, the 1971 Cyclone line was a carry over from 1970. The Cyclone competed for buyers at Lincoln-Mercury dealerships in the performance coupe segment when it was decided to offer the
De Tomaso Pantera exotic sports car beginning in 1971. ==Fifth generation (1972) ==
