Edelbrock, LLC is an American manufacturer of specialty automotive and motorcycle parts. The company is headquartered in the Memphis area (specifically Olive Branch, Mississippi), with a Southern California R&D Tech Center located in Cerritos, CA. The Edelbrock Sand Cast and Permanent Mold Manufacturing foundries are located in San Jacinto, CA. Edelbrock has two facilities in North Carolina: the Edelbrock Carburetor Division in Sanford, and the Edelbrock Race Center in Mooresville.

Key Information

Vic Edelbrock founded the corporation in 1938 when his desire to increase the performance of his 1932 Ford Roadster led him to design a new intake manifold,[3] friends and fellow drivers soon wanted one as well. This transformed his repair garage into a parts manufacturing enterprise, making one-of-a-kind equipment for automobiles.

History

[edit]

Origins

[edit]

Main article: Vic Edelbrock

Vic Edelbrock Sr. was born in a small farming community of Eudora, Kansas in 1913. After the family grocery store burned down in 1927, he left school at the age of 14 to help support the family by ferrying Model T Fords from Wichita to the many outlying farms in the area. The frequent stops to replace parts that shook loose on the region's dirt roads made him an expert at impromptu repair work.[4][5] Soon after, he found work in a local repair shop, working as an auto mechanic.[6]

When the Great Depression hit in 1931, Edelbrock went to California to live with his brother, Carl. Initially, he moved in with his brother and took a job as an auto mechanic. In order to earn some extra money to open his own repair shop, Edelbrock took an evening job in downtown Los Angeles parking cars at a large apartment complex. It was a chance encounter at this parking complex where he bumped into the 19-year-old Irish woman, Katherine (Katie) Collins, who was working as a day maid. Despite the fact that Katie was engaged, Edelbrock convinced her to give him a chance and not marry her fiancé. Vic and Katie married in June 1933, just eight weeks after meeting.[4]

As a 22-year-old, Edelbrock teamed up with his new brother-in-law to open his first automobile repair shop on Wilshire Boulevard in Beverly Hills.[5] Business flourished and in 1934 Edelbrock moved into his own shop on the corner of Venice Blvd and Hoover in Los Angeles.[4] Business continued to grow rapidly and he moved his shop three more times in the 1930s.[7] In 1936, Katie Edelbrock gave birth to Vic, Jr., the couple's only child.[4]

The Slingshot

[edit]
Edelbrock's first commercial product: The Slingshot manifold

In 1938 Vic Edelbrock bought his first project car, a 1932 Ford Roadster. In his desire to increase the performance, he joined with Tommy Thickstun to design a new intake manifold for the roadster's flathead engine.[3] Unhappy with the performance of that manifold, Edelbrock designed his own, nicknamed The Slingshot.[8] Most importantly, the new manifold allowed two Stromberg 97 carburetors to be used, eliminating a bottleneck that limited the engine's horsepower.[9] The manifold was tested for quality at the Muroc dry lake (occupied today by Edwards Air Force Base), which was a testing ground for Edelbrock and many other car clubs and racing associations.[5] On November 16, 1941, after stripping off the fenders and hubcaps, Edelbrock set a national speed record in the flying quarter mile with a speed of 121.45 mph (195.45 km/h).[10][11] Originally, he had no intention of producing any additional manifolds, but the overwhelming response following his phenomenal speed in a 1932 Ford prompted Edelbrock to make more. This was the first product that he sold commercially and marked the beginning of the company as it is known today. Edelbrock ultimately manufactured 100 of the Slingshot manifolds.[4]

Early years

[edit]
Edelbrock's first catalog (1946)

During World War II, Edelbrock's machinist skills were put to work in the Todd Shipyards in Long Beach, hand fabricating and welding aircraft parts. The Office of Defense Transportation placed a ban on auto racing during the war, but Edelbrock discreetly designed and developed a new line of products.[4] After the war, he produced aluminum racing cylinder heads, in addition to manifolds, which quickly gained him notability among hot rodding hobbyists. Parts to increase an engine's performance were not readily available, so racers built their own. Soon Edelbrock found himself building pieces first for his friends and then for customers.[12]

To deal with the enormous amount of mail he was receiving by 1946 Edelbrock created the company's first catalog, Edelbrock Power and Speed Equipment, with the help of Robert E. "Pete" Petersen. This hastened the transformation of the Edelbrock company from a repair garage into a performance parts manufacturer. Then, in 1947, Edelbrock produced the first cylinder heads for the Ford flathead.

One of the first companies to use an engine dynamometer, Edelbrock moved to a 5,000 sq ft shop in 1949 to develop more manifolds, cylinder heads and racing pistons. In the early 1950s, he continued to dominate the dry lakes and expanded his racing to the Bonneville Speedway.[4]

Racing

[edit]

After the war, the California Roadster Association (CRA) was formed to run auto races with roadsters that raced on oval track and attempted land speed records on dry lakes. After World War II, the CRA began sanctioning sprint car races.[13] In 1946, Edelbrock decided to expand his involvement into midget car racing, purchasing a car made by Frank Kurtis. In addition to racing the car, he wanted a test bench for the racing products he was developing.[14] Edelbrock's team toured the dirt track racing circuit of Southern California with flathead guru Bobby Meeks tuning the cars.[15] Many famous drivers were part of the Edelbrock team, including Walt Faulkner (first rookie to win pole at the Indy 500), Bill Vukovich (Indy 500 winner in ’53 and ’54), Rodger Ward (Indy 500 winner in ’59 and ’62), Cal Niday, Perry Grimm, Danny Oakes, Harry Stockman and Bill Zaring.[14][16]

The famed No. 27 Edelbrock midget racing car

A major claim to fame for Edelbrock was beating all the Offenhauser-powered midget cars that had dominated midget car racing for several years; a remarkable feat because Offenhausers had a significant power advantage over all the other engines.[17] Using his Kurtis Kraft V8-60 "shaker" midget car powered by a secret blend of 20% nitromethane (disguised with the scent of orange oil),[10] Rodger Ward made history on August 10, 1950, when his Edelbrock-powered #27 car broke the winning streak of the "Offy"-equipped midget cars at Gilmore Stadium, the track that originated midget car racing.[17] This was the only V8-60 to ever beat the Offys in the Gilmore 386-Race history.[18] The same car raced at the Orange Show Stadium in San Bernardino the following night, again beating the Offenhauser cars.[19] This feat was never duplicated in the history of midget racing.[12] Edelbrock was not the only racer in that era to experiment with nitromethane; fellow racers Joaquin Arnett and Tony Capanna had tried it in their hot rods, as well. Edelbrock, however, is generally considered to be the one who pulled it all together and made the volatile fuel work.[20]

Turning points

[edit]
Edelbrock's best selling product: The Chevy small-block intake manifold

Until 1955, Edelbrock made parts only for the Ford Motor Company.[8] Few things affected the company (as well as the development of the hot rod market) more than the development of the Chevrolet small-block engine (now referenced by the retronym Gen I as to distinguish between generations of the said Chevrolet engine) in 1955. Chevrolet delivered three small block engines to Edelbrock for experimentation. He used one engine for testing on a dynamometer and another to test multi-carb manifolds for magazine articles. He prepared the third engine for boat builder Henry Lauterback, who immediately set two world records in Miami, Florida.[4]

In 1958, Edelbrock managed an industry first by extracting one horsepower per cubic-inch from a 283 cid small-block Chevy that was equipped with his newly designed Cross Ram Manifold. This breakthrough led him to begin producing manifolds for Pontiac and Chrysler engines.[8]

Another critical turning point in the company's history was the 1964 decision to build a four-barrel intake manifold for the small-block Chevrolet. The C-4B manifold, developed with help from Bob Joehnck, opened the door to a new line of performance products. Although competing with the factory was a risky proposition, it turned out to be a beneficial one, as it allowed the company to expand into a new market.[21]

Growth

[edit]
Edelbrock's corporate headquarters in Torrance, California

In 1962, cancer claimed the life of Victor Edelbrock, Sr. at the age of 49. At the time, the company consisted of ten employees and annual sales were $450,000.[22] Edelbrock was succeeded by his only son, 26-year-old Vic Edelbrock, Jr.[23] Vic Jr., who had graduated with a degree in business from USC in 1958, became president and chief executive officer, a position he held until 2010.[24]

The company joined SEMA (the Specialty Equipment Market Association) as a charter member in the 1960s, with Vic Edelbrock, Jr. serving as president from 1971 to 1974. Edelbrock had been elected in a crucial time in the history of SEMA;[11] Congress enacted the Clean Air Act in 1971 and established the Environmental Protection Agency, which targeted the air pollution caused by internal combustion engines.[4]

When gas prices soared in the 1970s, Edelbrock produced its Streetmaster line of intake manifolds that featured improved mileage, as well as performance.[5]

In 1987, Edelbrock moved its facilities to its current location in Torrance, California. The five-building corporate facility occupies over 400,000 square feet (37,000 m2).[3] In 1990, Edelbrock built a 73,000-square-foot (6,800 m2) sand-cast aluminum foundry in San Jacinto, which employed 75 to 100 workers, and gave the company the ability to increase production according to market demands.[25]

In 1994, the Edelbrock corporation went public, selling shares of stock on the NASDAQ stock exchange. This initially raised $21 million, which was used mainly for construction of a new exhaust division in Torrance near its main facilities.[26]

Russell logo

In 2000, Russell Performance Plumbing, a company that manufactures fittings and hoses, was acquired by Edelbrock. The company, which had been based in Florida, was relocated to Torrance by 2001.

As of June 30, 2004, the company employed 722 persons, and achieved revenues of $125.98 million USD.[2] Since the company went private again in 2004, revenue findings have not been available to the general public.

On June 7, 2010, the Chicago-based private equity firm Industrial Opportunity Partners (IOP) acquired Edelbrock Corporation.[27][28]

In January 2021, the company was announced that its headquarters would be relocated to the Memphis, Tennessee region.[29]

Modern-day racing

[edit]
The Edelbrock sticker on a NASCAR racecar

The Edelbrock logo is prevalent in NASCAR but the company does not sponsor a racing team. Instead it engages in advertising through a $250,000 per year (2004) contract with NASCAR by which the Edelbrock contingency sticker is placed on every NASCAR race car. Contingency is a common form of "after the fact" sponsorship whereby racers place stickers on their vehicles from companies that post monetary awards to racing teams for winning, in exchange for the right to use images of winning drivers and their cars in promotional literature and advertising.

Edelbrock also posts contingency awards for drag racers, including NHRA sportsman categories. Since 2002, Edelbrock has been the title sponsor of the PRO Edelbrock Drag Racing Series, which features both professional and sportsman racing classes. The racing series includes seven classes of heads-up style racing and three classes of index style racing.[30]

In 2021, Edelbrock partnered with Ilmor to build engines for the Superstar Racing Experience. Using the Ilmor 396 as a base, Edelbrock provides components such as the camshaft and ignition coils.[31]

Products

[edit]

Eighty years after Vic Edelbrock Sr. manufactured the first Flathead Ford intake manifold, the Edelbrock company now designs and manufactures camshaft and lifter kits, carburetors, crate engines, cylinder heads, electronic fuel injection, engine blocks, engine dress-up, fuel pumps, intake manifolds, nitrous oxide injection, power packages, superchargers, top end kits, valvetrain, and water pumps. The company relies on online and catalog resellers along with traditional brick-and-mortar retailers. In 2018, Edelbrock launched a direct-to-consumer e-commerce website.

Historical Development

Origins in Hot Rodding (1920s-1930s)

Hot rodding emerged in during the late 1920s amid the era and the , as young enthusiasts modified affordable and Model A vehicles for speed rather than luxury, racing them on vast beds like Muroc—now the site of —in the Mojave Desert to avoid urban traffic laws. These informal gatherings evolved into organized speed trials by the early 1930s, fostering a culture of DIY where participants stripped unnecessary weight, tuned ignitions, and sought greater power from basic engines to push boundaries on the salt flats. The movement's epicenter in and surrounding areas attracted mechanics and gearheads experimenting with bolt-on modifications to achieve higher velocities, laying the groundwork for the aftermarket industry. The introduction of Ford's flathead in 1932 revolutionized hot rodding, becoming the staple powerplant due to its affordable cast-iron block, side-valve design, and accessibility in everyday vehicles like the 1932 Ford "Deuce" roadster. This 221-cubic-inch engine, producing around 65 horsepower stock, suffered from airflow restrictions in its stock intake and exhaust, prompting rodders to pursue common upgrades such as higher-compression cylinder heads, dual carburetors, and custom intake manifolds to improve breathing and boost output. These modifications addressed the flathead's inherent limitations, enabling speeds over 100 mph on dry lakes while keeping costs low for working-class enthusiasts. Vic Edelbrock Sr., born in 1913 in , relocated to in 1931 during the Depression and quickly established himself as a skilled , opening his first repair shop in Beverly Hills in 1933 with his brother-in-law before moving to a larger facility in by 1934. By the mid-1930s, he was building and customizing speed equipment in his machine shops, drawing on his repair expertise to experiment with performance enhancements for flathead engines, and he regularly tested parts at dry lake events like those at El Mirage and Muroc. Edelbrock networked within the tight-knit community, collaborating with pioneers such as specialist Ed Winfield, whose components complemented his own innovations in airflow and tuning. In 1936-1937, Edelbrock prototyped his first intake manifold by casting it himself in his shop, designing it to optimize airflow on the flathead V8 and increase horsepower from the stock 65 levels to over 100 through better fuel distribution and dual-carb setup. This hands-on experimentation, conducted ahead of formal production, reflected the era's grassroots innovation and directly influenced his later commercial designs, tested successfully at El Mirage where his modified roadster achieved 112 mph in 1938.

Post-War Innovations and Growth (1940s-1950s)

Following , the hot rodding movement surged as returning American GIs, supported by the for and , channeled their mechanical skills into modifying affordable pre-war cars using surplus parts like drop tanks for bodywork and engines from jeeps and . Edelbrock capitalized on this enthusiasm by opening a dedicated in 1946 at 1200 North Highland Avenue in Hollywood, , focused on producing high-performance aluminum components for Flathead Ford engines, and releasing the company's inaugural catalog, "Edelbrock Power and Speed Equipment," which included cylinder heads, intake manifolds, pistons, and related parts. To accommodate expanding demand, Edelbrock relocated in to a new 5,000-square-foot facility on Jefferson Boulevard in , enabling scaled-up manufacturing of aluminum cylinder heads, intake manifolds, and racing pistons while growing its workforce beyond the initial core team. material shortages posed challenges, but Vic Edelbrock Sr. prioritized lightweight aluminum castings for performance gains, with in-house wooden patterns hand-carved to create precise molds that reduced weight without sacrificing durability. Vic Edelbrock Sr. showcased early innovations through his iconic roadster hot rod, equipped with the company's signature dual-carburetor intake manifold and custom heads, which achieved over 120 mph at dry lakes in the late 1940s and contributed to record-setting runs at Bonneville starting in 1949. In 1948, Edelbrock introduced advanced dual-carburetor setups optimized for Flathead engines, enhancing airflow and power, and acquired a 200-horsepower Clayton for precise testing to refine designs for . By 1950, the product line had diversified to include more than 50 intake manifold variations tailored for hot rods and competition, emphasizing 180-degree designs for improved and efficiency. Edelbrock also entered in 1946, equipping with modified Flathead and V8-60 engines that secured victories at venues like in , driven by champions including and . Throughout the , these engines powered winning midget teams at prominent tracks, including events at the fairgrounds, solidifying Edelbrock's reputation in oval-track competition.

Expansion Amid Challenges (1960s-1970s)

In 1962, Vic Edelbrock Sr. passed away from cancer at the age of 49, leaving the company to his 26-year-old son, Vic Edelbrock Jr., who assumed the role of president and CEO alongside a team of loyal employees. Under Vic Jr.'s leadership, the company continued its focus on performance parts for hot rodders and racers, emphasizing innovation amid the burgeoning era. The introduction of the Performer intake manifold in 1982 marked a significant alignment with the rising demand for high-performance components in vehicles like the and , targeting small-block Chevy engines for street and applications. By 1970, Edelbrock had expanded its catalog to over 200 products, including its first aluminum cylinder heads designed for modern V8 engines, alongside complete engine packages featuring matched intakes, cams, and carburetors to support the era's powerful factory muscle cars. This product evolution capitalized on the hot rodding culture, with manifolds like the Tunnel Ram and further enhancing high-RPM performance for drag and oval-track . The 1970s brought substantial challenges for Edelbrock, as the oil crisis and stringent emissions regulations curtailed the boom and shifted consumer priorities toward and compliance. Sales dipped temporarily due to reduced demand for high-performance parts, but the company adapted by developing smog-legal carburetors and intake manifolds, such as the Streetmaster series, which improved drivability and economy while meeting (CARB) standards. Edelbrock also pioneered early electronic (EFI) prototypes and established an in-house emissions lab to certify products, ensuring continued market access; these efforts, bolstered by racing endorsements from and NHRA teams, facilitated a rebound in sales through the decade. Despite the hurdles, Edelbrock achieved steady growth, with annual revenue increasing from approximately $450,000 in 1962 to multimillion-dollar levels by the late 1970s, reflecting expanded production and market penetration. In 1976, the company acquired tooling from Carter Carburetor, enabling the launch of the Performer Series carburetors, which became staples for emissions-compliant street performance and further diversified the product line. This period solidified Edelbrock's transition from a niche hot rod supplier to a broader aftermarket leader, navigating economic and regulatory shifts while maintaining its racing heritage.

Corporate Maturation (1980s-1990s)

Under the leadership of Vic Edelbrock Jr., who had assumed control of the company in 1962 following his father's death, Edelbrock Corporation underwent significant professionalization during the and 1990s, transitioning from a niche supplier to a diversified aftermarket leader. In 1985, the company hired Dr. Rick Roberts, a Caltech PhD in , to head its efforts, emphasizing rigorous testing and innovation in . This period saw the solidification of core product lines, including the launch of the Victor Series racing manifolds in the , which became staples for high-performance applications across various types. By broadening its inventory to encompass , components, aluminum heads, exhaust systems, and water pumps, Edelbrock positioned itself to serve both enthusiasts and markets. Facility expansions underscored the company's maturation, with the completion of a 37,000-square-foot building in , in 1994 dedicated to exhaust product manufacturing, followed by a 45,000-square-foot addition in 1996 for research, development, and testing, and a 15,000-square-foot warehouse in San Jacinto that same year. The 1994 raised $21 million, enabling investments in equipment and further growth, while acquisitions like QwikSilver II, Inc., in 1995 for $500,000 expanded into marine applications and the sector with Harley-Davidson-compatible parts starting that year. In 1996, Edelbrock acquired the aluminum manifold assets from Holley , enhancing its induction system portfolio. These moves diversified revenue streams, with sales climbing from $67 million in fiscal 1995 to $108.9 million in fiscal 1999. Market strategies focused on quality U.S. to differentiate from rising , while family continuity remained central—Vic Jr. retained significant ownership, with the family holding nearly 50% of shares by 1999, and prioritized hiring engineering talent from top institutions to sustain . Although specific OEM partnerships with GM and Ford were not formalized, Edelbrock developed compatible components inspired by their designs, such as Vortec-style heads introduced in the late , including the E-Tec series around 2000 for enhanced compatibility and performance. International distribution grew modestly in the late , supporting exports to and , though major global push came post-2000. By emphasizing domestic production and engineering expertise, Edelbrock navigated challenges, achieving over 5,000 part numbers by the decade's end and solidifying its role in the performance aftermarket.

21st-Century Transformations

In the early , Edelbrock experienced significant growth, including the launch of its E-Force kits tailored for models, which debuted for the 2005-2009 4.6L 3V engines and delivered up to 466 horsepower and 439 ft-lbs of torque. By 2004, under the leadership of Vic Edelbrock Jr., the company's annual revenue had surpassed $125 million, reflecting robust expansion in the performance aftermarket sector. That year, Edelbrock transitioned to private ownership through a led by its chairman, marking a shift from public trading to focus on long-term strategic development.
