    Cast-Iron Production LS-Series Engine Blocks

    • Supports 500+ Horsepower


    Manufacturer's Part Number:

    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 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!

  • Deep-Skirt Casting (the block side extends below the crankshaft centerline)
  • 6-Bolt Cross-bolted Main Caps
  • Strong and Lightweight Aluminum Alloy Casting (most production blocks)
  • Provisions for the latest in Engine Control Management
  • 9.240" Standard Deck Height
  • 2.560" Standard LS Crankshaft Journal Diameter
  • 1-Piece Rear Main Seal
  • Optional Wet or Dry Sump Oiling

    Does this block require machining, or is it ready for direct assembly?

    Asked by: Ziptie06
    This should be ready for assembly assuming that the finish bore is the size that you need for your application.
