Stock location refers to the point where the transmission meets the engine. There are adjustable and stock location adapter plates available (also known as 1-inch setback plates). Adapter plates bolt onto the LS engine block, allowing you to bolt the engine securely to the crossmember. The motor mount adapter plates are the foundation to a successful LS swap. The LS3 and LS7 engines run anywhere between $7000 and $12000. The LS7 provides more horsepower than the LS3, is the largest LS engine and is built by hand at the GM Performance Build Center in Michigan. The LS3 was first released in the 2008 Corvette and was the most powerful Corvette engine to date.
