This is a 1939/1940 Alfa Romeo 6C 2500 with chassis number 913213 and engine number 923871. It is fitted with a Mille Miglia Spider body. The chassis was originally fitted with a Touring 5 seat body. The Super Sport engine is correct to the current body; complete with the three side draft Weber carburetors.
This car has run the California Mille Miglia and the Monterey Historic races and participated in various Concours events. It won the Mille Miglia at the Palo Alto Concours in 2005.
Ken Shaff and I (Conrad Stevenson) bought this car in 1991 as a total project --- it had not body but lots of spare parts, so this really is a resurrection or recreation made from original pre-war parts. The chassis #913213 is a 1939/1940 and was registered in Madrid(Spain) at some time in the 1950s. The insurance tags are still on the firewall. The engine is also a pre-war Super Sport motor, correct to the body configuration that the car now has.
This body style is known as a 6C 2500 SS Corsa. These Mille Miglia race cars have 6 cylinder twin cam normally aspirated motors using three single barrel side draft Weber carburetors, wheras the other Alfa Romeo 8 cylinder cars were supercharged. While the 2500 models had substantially less power than the supercharged cars, their better fuel mileage enable them to carry less fuel and be lighter as result, a benefit for the longer events. Unfortunately the Mille Miglia was shortened during the war.
Ken Shaff pssed away after this car ws completed but he and I ran the car in the California Mille Miglia (2004) and a CSRG event at Sears Point/Infineonraceway in 2005. More than anything this car is a tribute to Ken Shaff who was regarded by anyone who knew him as a true gentleman and a greatly missed friend.Also photographed at :
