According to published figures, this four-speed, Ram Air, 428 Cobra Jet-equipped 1970 Mercury Cougar XR7 convertible is one rare cat. Combining its color combination with the muscle car’s powertrain options narrows its production number to just one example in existence.
Let’s break it down: Just 66 XR-7 convertibles were built with the 428 CJ engine for the 1970 model year. Only 17 of them, like this one, were equipped with the four-speed manual transmission. That’s not all: The Marti Report reveals that two of those 17 muscle cars were sprayed with Competition Blue paint from the factory, and just one received black leather interior. This is that car.
This rare Q-code Mercury Cobra Jet also received a long list of factory options, including a black power top, center console, power front disc brakes, power steering, intermittent wipers, and more. It received a rotisserie-type restoration in 2015. According to the auction listing details on Hemmings, the car was finished to a concours-level, sticking as closely to factory specs as possible down to its blue paint. It has only seen 200 miles since completion.
The restoration included the installation of a confirmed period-correct (but not numbers-matching) 428-cu.in. Cobra Jet V8. The engine was enhanced with hardened valve seats for unleaded fuel compatibility, and the build included balancing and blueprinting. The mean muscle machine produced 391 horsepower and 485 lb.-ft. of torque during dyno testing.
From the factory, the 1969-1970 428 Cobra Jet engines packed 335 horsepower at 5,200 RPM and 440 lb.-ft. of torque at 3,400 RPM. Ford 428 Cobra Jet power was also available in a handful of other models from 1968 to 1970, including the 1968-1970 Ford Mustang, 1968 and ‘69 Ford Fairlane, 1968- ‘69 Ford Torino, 1969 Ford Cobra, the 1968 and ‘69 Mercury Cyclone and CJ, 1969 Mercury Montego, and the 1968 Mercury Comet and Shelby GT500KR. Muscle car enthusiasts will be hard pressed to find such a unique Cobra Jet-equipped car on the market than this 1970 Mercury Cougar XR7 Convertible.
