LQ4
The LQ4 is referred to as the Vortec 6000 by General Motors. The engine is 366 cubic inches in displacement, with a 101.6mm bore, a 92mm stroke, a 4.0-inch bore, and a 3.622-inch stroke. The engine features 300 to 325 horsepower and 360 to 370 pound-feet of torque, depending upon the type of engine heads. (Early models were equipped with cast-iron heads.) In 2005, GM began putting the LQ9 floating wrist pin rods in the LQ4 engines, but the company utilized dished pistons instead of flat-top pistons.
Copied from the net but you get the jist. The LQ9 is a high performance version.
These blocks can handle alot of power and are a great inexpensive platform for a hot rod.
