WARREN, MI—General Motors Co. plans to invest $70 million into its Tonawanda, NY, engine plant and more than $6 million in its Parma, OH, metal stamping plant. The investments are intended to support demand for GM’s Chevrolet Silverado and GMC Sierra pickups.

The Tonawanda investment will be used to increase capacity on the engine block machining line and the Parma investment will be used to construct four new metal assembly cells to support increased truck production volumes.

Tonawanda produces the 4.3-liter V-6, 5.3-liter V-8, and the 6.2-liter V-8 Ecotec3 family of engines for the Chevrolet Silverado, Suburban and Tahoe, GMC Yukon and Yukon Denali, and Cadillac Escalade. In addition, the plant builds the 6.6-liter small-block gas V-8 engine for the Chevrolet Silverado HD and GMC Sierra HD pickups. The Tonawanda engine plant is home to approximately 1,300 employees.

The Parma Metal Center processes more than 800 tons of steel per day and services and supports approximately 35 customers, including the majority of vehicles produced in North America by General Motors. Parma has more than 750 total dies and can produce up to 100 million parts per year. The manufacturing processes include small, medium and large transfer press lines, high-speed progressive presses, and a world class cut-to-length shear. The facility also has stand-alone, multi-cell, resistance and laser welding metal assembly operations. Parma employs approximately 1,000 people.
