Para las 12 Horas de Sebring (USA, 1964), prueba puntuable para el Campeonato del Mundo de Marcas, Carroll Shelby, director y propietario del equipo «Shelby American Corp.», inscribió cuatro vehículos: el modelo de la fotografía, un Shelby Cobra «Daytona» Coupé -únicamente se construyeron 6 unidades-, 2 Shelby Cobra roadster 4.7 V8 (encomendados a Bob Bondurant-Lew Spencer y Dan Gurney-Bob Johnson, del que habían seis unidades más conducidas por otros equipos privados) y un Shelby Cobra 427/7.0 V8 para Ken Miles-John Morton (retirados por problemas de motor). Pero la palma de la espectacularidad se la llevó el vehículo de la imagen, un Shelby achaparrado, de cola truncada y morro pronunciado, obra del ingeniero Peter Brock bajo el asesoramiento de Carroll Shelby. Adapta un propulsor V8 de 4.7 litros (385 CV a 6.750 rpm) alimentados por 4 carburadores Weber de doble garganta, caja manual (Borg-Warner T10) de 4 velocidades y un peso total de 1.045 kilos. Un monstruo mecánico… En Sebring, conducido por Bob Holbert y Dave MacDonald (ver imagen), se aupaban hasta el 4º puesto de la Scratch y serían 1º en la categoría de los Gran Turismos. Sus compañeros de equipo (Bondurant-Spencer y Gurney -Johnson), a los mandos de los roadster, se clasificaban 5º y 10º de la General, respectivamente… Éxito rotundo de las manufacturas americanas concebidas por el venerable Carroll Shelby.
