1979 Bizzarrini P538

538 B04racingItaly
Engine
5.3L (327 cu. in.) Chevrolet small-block V8, four side-draft Weber carburetors with crossflow manifold

The Bizzarrini P538 is a rare mid-engined racing spider bodied by Giorgetto Giugiaro and powered by a Chevrolet 327 cubic-inch small-block V8. Two examples were entered at the 1966 Le Mans 24 Hours, both failing to finish. This particular chassis, B04, was commissioned after the company's 1970 bankruptcy by Frenchman Jacques Lavost — later director of the French Iso and Bizzarrini owners club — and completed in 1979 following an extended construction period. Notable features include enlarged door air intakes and triangular roll bars, plus a unique crossflow intake manifold fabricated by former Bizzarrini foreman Salvatore Diomante.
