The Endurance V-8 breathes through a pair of UNI filters and an owner-fabricated intake. The engine's lower end is completely stock, and was assembled by Kurt with the help of his 11-year-old son, Trevor. When Kurt needed OEM parts for the engine, he called on Gary Braddy at Mossy Nissan's expertise. Long-time friends Clark Steppler and Jim Wolf of Jim Wolf Technology helped Scherbaum wring extra power out of the engine. A few different sets of cams were tried before a final grind was selected. This motor makes 500 ponies at the crank, and puts over 400 to the rear wheels.
