When torque is king, choose factor-engineered Big-Block power from Chevrolet Performance.
The classic Big-Block production engine was introduced in 1965. Cylinder-block casting combines traditional Big-Block heritage and modern production techniques for 21st-century performance.
Born from a full line of high-quality, precision-machined components based on performance-proven GM designs, a Bowtie Sportsman block packs big power and long-lasting reliability ideal for drag racers and street machines.
Built from premium materials and precision machined to blueprinted specifications, this fabled aluminum 427-cubic-inch Big-Block lets mere mortals experience the raw horsepower and tremendous torque of the ZL1.
With thick deck surfaces and splayed 4-bolt steel bearing caps, a cast-iron Bowtie Race Block is the starting point for drag racers looking for custom-machined performance.
Specifically designed with 500-cubic-inch Pro Stock engines in mind, the DRCE (Drag Racing Competition Engine) family of Big-Blocks is the foundation of many Pro Stock drag-racing engines.
