Designed as a follow-up to the AC Cobra, the 428 Frua was first introduced in prototype form at the 1965 Earls Court Motor Show before a production convertible debuted a year later, followed shortly after by a fastback coupe variant. Construction incorporated a development of the Mark III Cobra chassis with its wheelbase stretched by 6” that was sent to Turin, Italy, to be fitted with coachwork before returning to England for the installation of a 428ci Ford FE powerplant.
This example’s steel body incorporates an aluminum hood, trunk lid, and door panels and is said to have originally been finished in pale green before undergoing a color change to white circa the 1970s. The body was again repainted with a change to its current red shade during the refurbishment performed in the late 1980s by the previous owner’s shop, JWF Restorations in Oregon. Features include a split front bumper, louvered fender vents, rectangular side mirrors, and a black canvas convertible top, the latter of which was fitted under current ownership.
Chrome wire wheels are secured by three-eared knock-offs and are wrapped in Avon 205R15 tires, while a matching spare is secured in the trunk. Stopping is handled by vacuum-assisted four-wheel hydraulic disc brakes with dual master cylinders.
The right-hand-drive cabin was re-trimmed under current ownership with black leather over the bucket seats and matching upholstery over the door panels, console, dash, and rear bulkhead. Replacement charcoal carpeting was also fitted at that time. Air conditioning is said to have been added in 1971, and additional features include power windows, black lap belts, a horseshoe shifter, and a lockable glovebox. The selling dealer notes that the passenger-side window functions intermittently and that an area of the upper trim on the driver-side door rubs against the door jamb.
The wood-rimmed steering wheel frames Smiths instrumentation including a 180-mph speedometer and an 8k-rpm tachometer flanking a clock and gauges monitoring fuel level, coolant temperature, amperage, oil pressure, and oil temperature. The five-digit odometer shows 31k miles, approximately 25 of which have been added under current ownership.
The 428ci Ford FE V8 is topped by a four-barrel carburetor and was factory rated at 345 horsepower and 462 lb-ft of torque. The engine was replaced in 1971, and a request for its installation from the second owner to AC Cars dated June 1971 is shown in the gallery below. The cooling system has been updated with dual electric cooling fans.
Power is sent to the rear wheels via a Ford C6 three-speed automatic transmission and a limited-slip differential. Suspension incorporates double wishbones and adjustable coilover shock absorbers at each corner.
