Hawks Motorsports proudly offers the BluePrint Engines BPP12110360 GM LS Compatible Bare Block, the ultimate foundation for builders looking to create extreme-displacement LS engines. Featuring a 9.705-inch tall deck height, 4.000-inch semi-finished bore, SIAM (siamesed) cylinder bores, and OEM-style steel billet 6-bolt main caps, this premium cast iron block is engineered to support engine combinations up to an incredible 519 cubic inches. Designed for naturally aspirated, turbocharged, supercharged, and nitrous-assisted applications, the BPP12110360 delivers the strength and reliability required for today's highest horsepower LS builds.

Manufactured from EN-GJL-250 high-strength cast iron, the block features reinforced bulkheads, thick cylinder walls, a priority main oiling system with center crossover, and precision CNC machining throughout. The OEM-style billet steel 6-bolt main caps provide exceptional crankshaft stability under extreme cylinder pressures, making this block an outstanding choice for drag racing, Pro Touring, marine, off-road, and high-performance street applications.

The 9.705-inch tall deck allows additional room for longer connecting rods and stroker crankshafts while maintaining compatibility with OEM-style LS timing covers, oil pumps, oil pans, rear covers, and valley covers. With support for a 4.185-inch maximum finished bore and 4.250-inch maximum stroke, the BPP12110360 offers virtually unlimited possibilities for professional engine builders seeking maximum displacement and durability.

Whether you're building a 427, 454, 482, 500, or massive 519 cubic inch LS stroker, the BPP12110360 provides race-proven strength, precision machining, and uncompromising reliability.
