I thought @CumminsPusher might like this. Milliken’s combination, the only one of its kind in X275, is a 6.8-liter Cummins (based on the production 6.7-liter) with an LSM billet aluminum block of full internal factory dimensions, bored .040-inches over. It sports a factory 6.7 Cummins crank, billet steel rods of stock dimension, Diamond pistons, a Hamilton roller camshaft, and Manton roller rockers. Wagler Motorsports provided the likewise factory dimension billet cylinder head with a factory exhaust manifold design, factory valve design, injectors, and injector feeds, and so on. Per the X275 rules, Milliken is permitted to use two power adders: a four-stage, .122-inch solenoid dry nitrous system coupled with an 88mm Garrett turbocharger. (It ran a [email protected] mph in the 8th mile. Not too shabby for a Cummins!)
