Hawks Motorsports offers the BluePrint Engines E632 GM Big Block Compatible 632 C.I. Power Adder Long Block Engine, a purpose-built high-performance foundation designed for enthusiasts looking to add serious horsepower through nitrous, superchargers, or turbochargers. Producing 775 horsepower and 750 lb-ft of torque naturally aspirated, this massive 632 cubic inch big block is engineered with the strength and durability required for extreme forced-induction applications.

Unlike traditional big block combinations, the E632 was specifically designed with a power-adder-ready rotating assembly, featuring forged internals, precision-machined components, and a lower 9.6:1 compression ratio to provide additional tuning flexibility under boost. The tall-deck GM Big Block compatible platform provides additional clearance and strength for high-output builds.

The E632 long block includes BluePrint PS8012 aluminum cylinder heads, hydraulic roller camshaft, forged crankshaft, forged pistons, dual-keyway SFI-rated harmonic balancer, timing cover, valve covers, oil pan, and dipstick. This engine is an excellent choice for high-horsepower street builds, drag racing applications, and custom projects requiring a durable big block foundation capable of handling additional power.
