1967 Mercury Cougar With GT500 Powertrain Up For Auction

Though it lives in the shadow of the Ford Mustang, the first-generation Mercury Cougar is still a pretty fantastic machine, and one that still commands big money at auction – particularly the rarer, more powerful examples. Every once in a while, we also come across modified examples with more modern powerplants, and that’s precisely the case with this 1967 Mercury Cougar up for grabs at Bring a Trailer, which is packing a pretty sweet engine under its long hood.

That engine is the supercharged Ford 5.4L V8 sourced from a 2007 Mustang Shelby GT500, which replaces the original 289 V8 that came with the car. That particular engine churned out 500 horsepower and 480 pound-feet of torque in stock form, but this one is also fitted with a Walbro fuel pump, a Kenne Bell Boost-A-Pump, an aluminum radiator and intercooler, and a custom Hotwire Auto engine harness, sending power to the rear wheels via a six-speed manual transmission and an 8.8-inch limited-slip differential.

Aside from that major modification, this 1967 Mercury Cougar has been resprayed with black paint, replacing the factory Maroon Metallic hue and covering straightened-out bodywork. That look is complemented by a set of 15-inch American Racing wheels wrapped with Cooper Cobra Radial G/T tires. Underneath, the seller also added a Mustang II-style front suspension with rack-and-pinion steering, along with four-wheel disc brakes with slotted and drilled rotors.

Inside the cabin, this Cougar features black leather bucket seats a leather-wrapped three-spoke steering wheel, a retro-look digital stereo, a heater, lap belts, and New Vintage USA instrumentation, helping the driver keep tabs on what’s going on under the hood. Overall, this is certainly a nice, clean build, and one that offers up far more performance than it did in stock form, to boot.
