  • Chevrolet Performance LS Series Engine Blocks

    Chevrolet took a chance with the LS engine. They stayed 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. The Chevrolet Performance LS Series cylinder blocks are designed specifically for late model small-block engines that run the LS Family cylinder heads. These include the LS1, LS2, LS4, LS6, LS7, LQ4, LQ9, and L76.********
