The investment was being made to repurpose flexible machining and assembly equipment to build V8 engines to meet market demand. The move was also set to retain approximately 200 jobs.
Officials said the investment would enable Spring Hill to quickly add capacity to build the Small Block 6.2L V8 engine in the popular truck and SUV segment.
They added it would be the first time Spring Hill would build V8 engines.
That engine has been available in the Chevrolet Silverado Crew Cab, GMC Sierra Crew Cab, Yukon Denali, Yukon XL Denali, and the Cadillac Escalade and Escalade ESV.
Representatives said other General Motors sites that build the 6.2L V8 for trucks included Tonawanda, New York and St. Catharines, Ontario.
The $148 million Spring Hill investment has been part of $709.4 million in investments GM has announced since ratification of the UAW-GM national agreement in 2015.
