Based on a sports racing car designed by John Tojeiro and introduced at the London Motor Show in October 1953, the Ace remains the signature product of the AC marque. Equipped with a four-wheel independent suspension and sleek bodywork reminiscent of contemporary Ferrari Barchettas, the Ace garnered praise from magazine testers, including John Bolster of Autosport who wrote, “the machine does all the right things all the time.” He continued, “no emergency or advanced driving technique will ever catch it on the wrong foot.”



In 1956, the highly regarded 1,971 cc Bristol ‘six’ became available, upgrading the standard Ace to “Ace Bristol” specification. Initially producing 103 hp and rising to 125 in its ultimate D2 specification, this state-of-the-art power unit traced its origins to BMW’s advanced prewar 328 design and continued to be successful in racing well into the 1960s.



Bristol-powered Aces were brilliant in competition, winning three successive SCCA E-Production championships between 1957 and 1959, followed by two D-Production championships in 1960 and 1961. The Ace Bristol also scored very well at Le Mans, where it finished second in class in 1957 and 1958 and achieved a sterling class victory and seventh overall in 1959. This performance no doubt left an impression on overall 1959 Le Mans champion Carroll Shelby, who later created his 289 and 427 Shelby Cobra derivatives of the classic Ace.



Chassis BEX 1090



This left-hand drive Bristol-powered Ace, chassis BEX 1090, was originally finished in white with a black-trimmed cockpit and equipped with factory-original options including a heater, oil cooler and oil-temperature gauge. It was purchased directly from the AC works by Charles Kaleta as a gift for his son Charles Jr., who planned to study in Switzerland. However, his program was cancelled and the young Mr. Kaleta returned with the Ace to complete his studies in the USA. Mr. Kaleta raced the Ace in one club-level event in Southern Wisconsin, and in 1962, he sold BEX 1090 to a University of Chicago professor. A number of owners followed, and eventually, respected AC marque specialist Jerry Bensinger found BEX 1090 in a Northern Ohio barn. Although it required complete restoration, the Ace remained wonderfully complete and unmolested.



While the car’s original VIN plate shows the engine number as 930 D2, the current engine is numbered 1000 D2. Through correspondence with AC Owner’s Club historians and following a search of their archives, the current owner has learned that the engine number “1000” was never factory-assigned to any Ace chassis. As a result, it is believed that the original Bristol engine was damaged early in the car’s lifetime and that the factory replaced it with the currently installed Bristol D2 engine, numbered 1000 D2.



The current owner purchased BEX 1090 with the objective of restoring it for extended and reliable touring, as well as for concours events and shows. Accordingly, equal attention was paid to its running and handling, as well as its cosmetics, with the suspension, steering, springs, shocks, brakes, instrumentation and wiring either replaced or restored. The respected firm, Marcovicci-Wentz of Long Island, New York, rebuilt the Bristol engine with work including all-new bearings, pistons and valves, and a 0.020-inch overbore. Upon completion, the Bristol was dynamometer-tested and tuned, with detailed reports produced.



Mark Wehrman, also of Long Island, rebuilt the four-speed gearbox and replaced all the bearings and worn parts. A proper Laycock electric overdrive unit, complete with correct switchgear, was sourced from England and provides extended highway-cruising capabilities. The original tail-shaft and miscellaneous transmission parts are also included with the sale of the car.



During restoration, the entire car was completely disassembled, but the body was not removed from the car’s tubular chassis to avoid the loss of critical alignment points. A rotisserie was fabricated to allow work on the body and chassis from all possible angles. All aluminum body panels were repaired or replaced, with work completed by the staff at Automotive Hammer Art of Indianapolis, Indiana. Once prepared, the Ace was refinished in dark blue and re-trimmed with black upholstery.



Once completed, which was approximately two years ago, the Ace was methodically road-tested over about 1,000 miles and thoroughly sorted in preparation for its entry into the Colorado Grand, where it performed brilliantly. Everyone admired it for its stunning appearance and strong performance on the mountain roads covered during the event. At present, there are only a little over 2,100 miles on its odometer since restoration.



An authentic and correct restoration, the car features such original-specification items as flocked rear-boot side panels, proper corrugated radiator hoses and clear, corrugated fuel lines, plus heavy, grease-impregnated covers for the front and rear leaf springs. The car is offered complete with a new top and tonneau cover, rebuilt and re-glazed side curtains, the original jack with handle, a grease gun and a “T” key. Correct storage bags for the top and side curtains, as well as the tool kit, were authentically created using patterns from a set of original items.



A comprehensive file accompanies the sale of the Ace and includes extensive restoration receipts and photographs. With its authentic and stunning high-point restoration and mechanical excellence, BEX 1090 is also very rare as one of just 465 Ace Bristols originally produced. A joy to drive, it can also be detailed easily for display on the concours field.
