Product Description:

Hawks Motorsports proudly offers the BluePrint Engines BPP12110361 GM LS Compatible Bare Block, a premium tall-deck LS foundation engineered for builders seeking maximum displacement, extreme durability, and uncompromising performance. Featuring a 9.705-inch tall deck height, 4.125-inch semi-finished bore, SIAM (siamesed) cylinder bores, and OEM-style steel billet 6-bolt main caps, this block is built to withstand the demands of naturally aspirated, turbocharged, supercharged, and nitrous-assisted racing applications.

Manufactured from EN-GJL-250 high-strength cast iron, the BPP12110361 incorporates reinforced bulkheads, thick cylinder walls, a priority main oiling system with center crossover, and precision CNC machining to provide exceptional crankshaft stability and long-term reliability under extreme horsepower. The 9.705-inch tall deck allows the use of longer connecting rods and stroker crankshafts while supporting engine combinations up to an incredible 519 cubic inches, making it ideal for professional racing and high-end street builds.

Designed to accept OEM-style LS timing covers, oil pumps, oil pans, rear covers, and valley covers, this block offers excellent compatibility with factory and aftermarket components. Whether you're building a 482, 500, or 519 cubic inch LS stroker, the BPP12110361 provides the strength and precision that serious engine builders demand.
