Alongside the production of nine Formula 3 Chevron B17 1 litre / 61 cui “Screamer” Formula 3 cars Chevron built 5 examples of the B17B powered by Vegatune Ford Twin Cam engines in 1598cc / 97.5 cui form for US based SCCA Formula B competitors and two B17C’s one with a 1598 cc / 91.5 cui Cosworth FVA engine to compete in Formula 2 and the other today’s featured chassis #F2-70-2 which was originally supplied to compete in Formula Libre events.

Steve Thompson had the car fitted with a 1790 cc / 109.2 cui Cosworth FVC engine and is believed to have won at least 14 Formula Libre races with the car in 1970. The ownership trail then includes Frank Mumford and Alex Seldon, the latter is believed to have fitted the car with a 2 litre / 122 cui BDA in 1972, but neither owner is known to have competed with the car.

In November 1972 Malcom Brown is believed to have raced the car at Brands Hatch and in April the following year Richard Leech drove the car in a Libre event as Castle Combe, Deryck Cook advertised the car for sale now powered by a Ford Twin Cam before Philip Sandwith in Guernsey bought it from Spencer Elton in Wiltshire.

Philip competed in hill climb events from 1975 to 1978 with #F2-70-2 now fitted with a Holbay twin cam engine that helped him secure numerous class records, Guernsey Bus garage manager Mike le Cras ran the car at the Le Val des Terres hill climb in St Peter Port Guernsey in 1983.

The ownership trail then leads to Australian Martin Bullock who is seen driving the car in these photographs at the Silverstone Classic press day in 2013, with a 1967 – 1971 Formula 2 spec Cosworth FVA fitted. More details on this car can be found on Allen Brown’s Old Racing Cars.com website.
