Ups and downs are part of any major automotive undertaking. However, some projects seem destined to fight you every step of the way. The latter certainly appeared to be true for Cory Jarriel and his LML Duramax. At every turn, the truck seemed to have different plans than he did. First, the truck fell off his two-post lift. Then, after considerable body work, came the electrical fire under the hood, followed by a factory connecting rod vacating the block. Then, once the new engine was in, the supposedly-built Allison sidelined the truck in less than 4,000 miles. Throughouteach setback, Cory—who has personally undergone two open-heart surgeries— kept his head-up and ultimately persevered. His reward? A show-ready (and reliable) ’13 Silverado 2500 HD packing four-digit horsepower and more than 2,100 lb-ft of twist.
When a factory connecting rod left the LML’s block somewhere near the 650-rwhp mark, Cory Jarriel pulled out all the stops when it came to building a new engine. In need of a Duramax that could withstand making four-digit horsepower, he turned to the folks at Wagler Competition Products. A Callies forged-steel crankshaft, ARP main studs, Wagler’s forged rods, Wagler-modified cast-aluminum Mahle Motorsport pistons, and one of the company’s alternate firing order camshafts reside in the crankcase. The heads were fitted with Wagler’s dual valve springs and anchored to the block via ARP head studs.
