    This is the ultimate race version of the aluminum LS block which enjoys the state-of-the-art technology necessary to build an LS engine to over 440 cubic inches, and 900 horsepower!

    *HIP is the acronym for Hot Isostatic Pressure. This process puts the blocks in a sealed vessel where a vacuum is first used to remove room air and any possible contaminants. The vessel is filled with high pressure nitrogen (up to 30,000-psi) and then heated to the required temperature and sustained for a determined amount of time. The cooling process is also a controlled procedure to ensure maximum strength and proper heat treat. This extreme high pressure and heat removes almost 100% of the internal porosities that are generated during the casting process. The material integrity, strength and fatigue life increases significantly.

  • Chevrolet Performance 12480030 - 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.********
