Mercury Cougar 1969 XR7 CJ 428 Convertible

This 1969 Mercury Cougar pairs the loaded XR7 trim with the top-shelf 428 Cobra Jet V8, a combination that turned out to be far rarer than the factory brochure let on. Mercury built roughly 100,000 Cougars that year, but only a small handful got this exact engine and trim pairing, with some production records citing as few as 53 built. The Cobra Jet came backed by heavy-duty axles and radiators built specifically to survive its power. That’s what actually made this the baddest Cougar money could buy in ’69.

Very cool 1969 Mercury Cougar, loaded with the XR7 option and the top-cat 428 Cobra Jet Ram Air V8! Add to that the convertible top, and you have about the baddest Cougar you could buy in ’69!!

Ordering the top engine option on a 1969 Mercury Cougar sounds simple enough, but doing it on an XR7 convertible turned this particular car into something closer to a unicorn than a factory option list would suggest. Mercury built roughly 100,000 Cougars that model year, and the overwhelming majority of them left the factory nowhere near this combination of trim and engine. The 428 Cobra Jet under the hood wasn’t just a big-block for bragging rights, either; Ford and Mercury built a specific package of driveline parts around it to make sure the rest of the car could survive what the engine was capable of. So just how rare is “the baddest Cougar you could buy in ’69,” really?

An Engine Built With Backup Parts in Mind

The 428 Cobra Jet made 335 horsepower at 5,200 rpm and 440 lb-ft of torque at 3,400 rpm, running a 10.6:1 compression ratio and a 730 CFM Holley four-barrel carburetor. Cars equipped with it came standard with beefed-up 31-spline rear axles and 24-inch heavy-duty radiators, hardware Ford specified specifically to handle the extra power and heat the Cobra Jet generated.

How Rare Is Rare?

Production records vary depending on the source. Some cite as few as 53 XR7 hardtops built with the 428 Cobra Jet in 1969, while others put total Cobra Jet-equipped Cougars closer to 127. Against total 1969 Cougar production of roughly 100,000 units, either number puts this exact combination of XR7 trim, convertible body, and Cobra Jet power in a tiny fraction of a percent of that year’s production.
