Today’s car is a 1970 AC 428 Convertible. It is finished in Green with a Biscuit leather interior. It is powered by a 350 hp, Ford FE 428 cu in, 7.0 liter, “Big Block” OHV V8, with Holley four barrel carburetor. It is mated to a Ford Toploader 4-speed synchronized manual transmission through a Salisbury limited slip differential with a 3.08:1 rear axle gear ratio. Slowing this rare beauty down are power assisted 3 pistons Girling disc brakes in all 4-corners. The front suspension is fully adjustable independent suspension with double triangular wishbones, coil spring and hydraulic telescopic shock absorbers. The rear suspension is adjustable independent suspension with double triangular wishbones, coil spring hydraulic telescopic shock absorbers.

The AC 428 were built from 1965 to 1973. During that period of time the total production was 81 cars of which 49 were coupes or fastbacks, 29 were convertibles, and and 3 special bodied cars. The MSRP was $8,982.00 and one recent sold for $302,000.00. The published top speed was 152 mph with a 0 to 60 time of 6.2 seconds.

The AC 428 or Frua 428 was designed by Pietro Frua, not by Caroll Shelby organization, for which it got its name. This is a beautiful example of a Gran Turismo (GT) British sports cars, with an Italian design and an American Engine. This is an extremely rare car and is the first one that I have ever seen. According to the owner, it is the only one ever to win Pebble Beach. This was such a treat to see this one at one our local events when you would usually only get to see one at Concours d’Elegance events. Thanks for riding along. Frank
