8V71 Open Exhaust in french GMC Astro
Un route de campagne Lorraine, un bruit infernal : Detroit Diesel in action ! Un copain me fait faire un tour avec sa dernière acquisition... GMC Astro de 1974, ex transport Marmeth de Nantua. Le moteur n'est pas un "banal" -6V92T mais bien un vrai V8 sans turbo, un rageur 8V71 qui permet une conduite sportive, et libère pleinement en échappement libre.
