A Chevron B27S will make its first post-restoration appearance at Vernasca Silver Flag in Italy from 28-30 June.
The car was built around a B23 chassis that was originally fitted with a 1930cc Ford unit. The chassis was then altered to accommodate a Cosworth DFV engine. It is the only Chevron sports prototype to be fitted with the fabled F1 powerplant.
To handle the extra power and torque, the car features a Hewland FG400 gearbox, ventilated disc brakes, Lockheed calipers with larger 15in wheels, and an adjustable rear wing.
The car made its debut at the 1974 Garessio-San Bernardo, taking first place with Eris Tondelli behind the wheel, but its biggest successes came with Mauro Nesti.
Known as the ‘king of the mountain’, the Italian broke numerous records with the car and guided it to fourth place at the Targa Florio in 1977 – the final year that the road race was held in its original format.
Having subsequently been sold and fitted with a different engine, the Chevron was discovered by collector Luigi Moreschi, who returned it to its original condition.
