I have written a Book about how I would personally run General Motors that you may purchase a copy of, online from Barnes & Noble if you wish to do so: https://www.barnesandnoble.com/w/how-i-would-manage-general-motors-if-i-were-the-companys-ceo-matthew-parij/1141501691?ean=9783180744681

If I were in charge of General Motors, I would order the development of modern Fuel Injected, Variable Valve Timed and Inducted, and Vermicular Graphite Cast Iron Block And Head versions of the GMC 305, 351, 379, and 401 Cubic Inch V6 Gasoline/Petrol Engines for Light And Medium-Duty Trucks and SUVs. I would also recommend the development of Hydrogen-fueled versions of these Engines.

For The Badge-Engineered Isuzu Class 8 Trucks that would be sold in the North American market as Chevrolets and GMCs, I would also order the development of the modern versions of the GMC 432 and 478 V6 Gasoline/Petrol Engines, the GMC 637 V8 Gasoline/Petrol Engine, and the GMC 702 V12 Gasoline/Petrol Engine. And I would recommend the development of Hydrogen-fueled versions of these Engines as well.
