ROCHESTER, NY -General Motors announced April 12 it will invest $100 million to add 30 jobs and purchase tooling and equipment to make future automotive components at its GM Components Holdings (GMCH) Rochester Operations.

The announcement brings the total investment for GM's new small block engine to nearly $1.1 billion, according to the automaker.

According to Cathy Clegg, GM vice president of Labor Relations, the investment in GM's manufacturing operations "will enable us to produce a new generation of fuel-efficient small block car and truck engines. The Gen V small block engine family will have unprecedented fuel efficiency, and GMCH Rochester Operations will play a key role in helping us deliver these efficient engines to our customers."

Four product lines will be enhanced: the integrated air module, a new high-pressure fuel rail, a new lifter oil manifold assembly, and a new direct injection injector. These parts will be shipped to GM Powertrain plants in Tonawanda, N.Y., St. Catharines, Ontario, Canada, and Ramos Arizpe, Mexico.

GMCH Rochester Operations opened in 1939 and provides components to support several GM products built in the U.S., Canada, Mexico, South Korea, China, Australia, and Brazil.
