General Motors plans to invest more than $150 million in its Saginaw Metal Casting Operations (SMCO) in Michigan to make the sixth generation of GM’s V-8 engine blocks and heads used in full-size pickup trucks.
This new commitment builds on the approximately $5.5 billion in investments GM made in 2025. In January 2023, the company announced a $500 million investment in its Flint Engine plant to produce the sixth generation of V-8 engines. The investment in SMCO will support this work.
The investment includes new equipment and tooling.
SMCO will continue to produce the fifth generation of GM’s V-8 engine blocks while the plant prepares for the next generation’s start of production in 2027.
SMCO is the third-oldest GM facility in the United States and has more than 300 employees across three shifts.
