Edelbrock Small-Block LS3 Victor CNC 11-Degreee Bare Cylinder Heads - 77670

The Edelbrock Victor CNC 11 6-Bolt Cylinder Heads for GM LS3 68cc Individual #77670 is specifically designed for high horsepower, naturally aspirated and boosted applications. Edelbrock Victor CNC 11 6-Bolt Cylinder Heads for GM LS3 engines utilize the popular LS 6-bolt design, making them compatible with the GM LSX block and all aftermarket iron or aluminum 6-bolt per cylinder LS race blocks. The 6-bolt design offers increased clamping capacity over the standard factory 4-bolt configuration and greatly improves head gasket sealing, making them ideal for high compression naturally aspirated engines and high boost applications. These heads are manufactured with premium materials and machined to the industry's tightest tolerances. Features include an 11 valve angle, copper infiltrated powder metal valve seats and fully CNC-machined ports for maximum airflow. The CNC-machined runners and chambers, as well as the rolled 11 valve angle, increase overall flow capability, while the revised water jacket design enhances thermal conductivity and tunability. The premium manganese bronze valve guides withstand long wear with emphasis placed on holding precision tolerances on valve seat concentricity, allowing the valves to seal securely, which eliminates leak down and increases cylinder pressure during engine operation. Finally, the .700 thick deck and reinforced rocker rails make these cylinder heads ideal for high horsepower applications. Edelbrock #77670 is a bare head.

About Edelbrock

Edelbrock was founded in 1938 by Vic Edelbrock Sr. in Los Angeles, California. Initially, the company focused on producing performance parts, with Vic's first major success being a high-performance intake manifold designed for flathead V8 engines. This innovation helped enhance engine efficiency and performance, laying the foundation for the company's reputation in the automotive aftermarket. Vic's love for racing also played a significant role in the early development of Edelbrock, as he designed parts to improve the speed and power of his own cars.

By the 1950s and 1960s, Edelbrock began to expand its product offerings, moving beyond intake manifolds to include carburetors, camshafts, and other components essential for performance cars. The company gained recognition in the burgeoning hot rod and drag racing scenes, particularly in California, where racing culture was rapidly growing. Edelbrock's products were highly regarded for their quality and performance, earning the company a loyal following among car enthusiasts and racers.

During the 1970s, the company solidified its position as a leader in the performance parts industry. With Vic Edelbrock Jr. joining the business, Edelbrock expanded its reach beyond racing into the street performance market, offering a variety of parts for muscle cars and street machines. The Edelbrock carburetor became a go-to choice for enthusiasts looking to boost engine performance, and the company continued to innovate, expanding its product line to meet the growing demands of car enthusiasts.

The 1980s and 1990s marked a period of continued growth for Edelbrock as the company advanced with cutting-edge technologies, such as the introduction of electronic fuel injection (EFI) systems and aluminum cylinder heads. Edelbrock was a key player in motorsports, supporting events in NASCAR, NHRA drag racing, and circle track racing. The company's emphasis on technological innovation helped it remain at the forefront of the performance parts industry.

In the 2000s, Edelbrock adapted to modern advancements in manufacturing, utilizing CNC-machining and computer modeling for greater precision in its products. The company also expanded its portfolio, delving into areas like superchargers, performance exhaust systems, and automotive electronics. As the market shifted, Edelbrock continued to develop high-performance parts to meet the needs of both racers and car enthusiasts.

In 2020, Edelbrock was acquired by Icahn Enterprises, a holding company controlled by investor Carl Icahn. Despite this change in ownership, Edelbrock has maintained its legacy as a trusted brand in automotive performance. The company continues to innovate with new products and technologies, ensuring that it remains a leader in the automotive aftermarket space.

Today, Edelbrock is a globally recognized name in the automotive performance industry. The company’s long history of innovation, dedication to quality, and commitment to performance has earned it a loyal customer base that includes racing professionals, car builders, and hobbyists alike. From its humble beginnings to its current standing as a giant in the performance parts world, Edelbrock’s legacy of excellence continues to shape the automotive landscape.
