Hawks Motorsports offers the BluePrint Engines E632SB GM Big Block Compatible 632 C.I. Pro Series Short Block, a premium foundation engineered for extreme naturally aspirated street, drag racing, marine, and custom performance engine builds. Built around BluePrint's BPE Eliminator platform, this short block features a fully forged rotating assembly, tall-deck cast iron block, and premium internal components designed to support massive cubic inches and exceptional horsepower potential.

The E632SB utilizes a high-strength cast iron tall deck block with a 4.600-inch bore and 4.750-inch forged steel crankshaft to achieve 632 cubic inches of displacement. A forged rotating assembly consisting of 6.635-inch forged H-beam connecting rods and 22cc forged dished pistons provides exceptional durability, while the internally balanced assembly and splayed 4-bolt main caps create a rock-solid foundation for high-RPM, high-horsepower applications. When paired with 118cc cylinder heads, the engine produces a 9.6:1 compression ratio, making it an excellent choice for premium pump gas naturally aspirated performance builds.

Manufactured and precision machined in the USA, the E632SB is sold as a professionally assembled short block, allowing builders to select their preferred cylinder heads, valvetrain, induction system, ignition, and accessories while starting with a race-quality bottom end. Every BluePrint short block is internally balanced and assembled using premium components for outstanding reliability and performance.
