While other diesels add a heavy markup for importing and shipping costs, not to mention advertising, Peninsular is built in the USA and would rather be a word of mouth company advertised by satisfied customers. Peninsular has dedicated the last ten years to designing and refining this engine to enhance its' performance and reliability. The 6.5 Liter was designed to replace 350, 454 and 502 CID engines with a minimum of expense. With torque rated @ 389 ft lbs to 600 ft lbs. @ 2700 rpm, the engine will deliver the power you need when you need it. So feel free to browse our website then compare pricing with other diesels in the same horsepower class.
