Chevrolet Performance LS-Series Engine Blocks

These Chevrolet Performance LS Series Engine Blocks are driving a new generation of street and racing enthusiasts by providing a foundation for serious performance achievements. Chevrolet took a chance with the LS engine, staying true to the pushrod small block and continued to develop this technology to the point that building a daily-driven, 500-plus HP car is no big deal. These blocks are designed specifically to handle from 450-900 horsepower on LS-Series cylinder head late model small block engines, which include the LS1, LS2, LS4, LS6, LS7, LQ4, LQ9, and L76. If you are building a full out track only racing engine or a mild street cruiser there is a strong and durable LS cylinder block available to assure that you produce the power you require safely!
