As of May 2026: Representing Saginaw plant workforce

General Motors is spending more than $150 million to retool a century-old casting plant in Saginaw, Michigan, for the company's next-generation 6.7-liter V-8 engine. The plant has poured engine blocks since 1919 and now employs about 300 workers. In 2027, it will begin producing components for the sixth-generation small-block V-8 destined for the Chevrolet Silverado HD and GMC Sierra HD pickup trucks.
