Dr. William Fox caught the automotive bug at the ripe old age of 6 when his grandfather built him an electric go-cart. He would study cars and call out their unique features when traveling with his parents. He particularly had a passion for classic cars. His personal goal was to have his dream car by the age of 40. He wanted to have something that was unique, had enough room for the kids and was fun to drive.
Dr. Fox reviewed several classic cars, but his criteria narrowed his search to the Chevrolet Chevelle. He was particularly attracted to the ’66 model – a perfect blend of styling that became an icon for the beginning of the muscle car age. “The knife-like front edge screams muscle. It has just enough of an edge to it yet comes across as a family sedan – a sleeper at the stop light,” said Dr. Fox.
Dr. Fox is having a blast in his dream machine. It’s his daily commute to work. It is a conversation piece at traffic lights, parking lots and drive-throughs. One thing he hasn’t done yet – to the chagrin of his son – is to provide him a ride to school so he can be the envy of classmates and teachers alike. Come on Dad – just once?
We are very excited to reveal Roadster Shop’s gorgeous ’66 Chevelle muscle car featuring our SB4 7.0 automotive crate engine.
Designed, developed and manufactured in-house, the 32-Valve DOHC SB4 7.0 engine adapts our proven high-performance valve train to a customized LS-based cylinder block that produces a staggering 750 naturally aspirated horsepower. Mercury Racing’s advanced four-valve cylinder head combustion system and dual overhead camshaft valve train provide significantly improved performance and durability compared to a standard two-valve design.
Roadster Shop is the exclusive SB4 distributor. The Mundelein, Illinois based company has been an automotive aftermarket industry mainstay in performance chassis fabrication and custom car building for over 30 years.
The project started with a call from Roadster Shop customer William Fox. William wanted to build a muscle car, something to compete with any late model European sports car. While reviewing available engine/power options William was intrigued by the new SB4 for its high rpm operating band and naturally aspirated, 750 horsepower.
The SB4 Chevelle qualified as a Roadster Shop “Survivor Series” build; a car that arrives clean in its original condition. The body is stock with the exception of some minor work to the transmission tunnel, and firewall. The paint, which ironically is very close to our Mercury Racing Blue, is original as are the chrome bumpers.
This iconic American muscle car has all the conveniences of a modern automobile. Roadster Shop re-engineered and rebuilt the complete vehicle. All new wiring and plumbing was installed. It features a custom Roadster Shop Fast Track chassis and high performance suspension. The SB4 is coupled to a Tremec/Bowler T56 6-speed transmission. Roadster Shop even built custom stainless steel headers and a complete exhaust system. Massive 345/40/19 (rear) and 265/40/18 (front) tires are mounted on all-new RS OE-2 wheels. A C& R Racing radiator keeps the SB4 cool as it runs through the gears up to its 8000 rpm rev limit.
The interior is updated with sound deadening material, modern instrumentation, cruise control, sound system and power windows. Recaro Expert seats provide support for the driver and passengers to comfortably experience the SB4’s full capabilities.
Roadster Shop debuted the SB4 Chevelle at the Goodguys 2018 PPG Nationals, July 6-8 in Columbus, Ohio. Roadster Shop personnel and fans alike were blown away with the SB4’s smooth idle and user friendly running qualities.
“This is by far the smoothest, cleanest performing engine we have ever used. It feels like its not even trying to make all of that power, almost effortless. The smoothness is noticeable throughout the entire rpm range, from idle to 8,000 rpm,” said Roadster Shop director of business development Josh Henning.
“This package really does a number on your senses. It gives you an organic analog connection to the car with a smooth powerband to create a hybrid muscle car/super car experience like we have never felt before.”
We are excited to see what Roadster Shop has planned next for the SB4. You can be assured it will be the baddest build in its class.

Greetings from Las Vegas! We are here for the 50th Anniversary SEMA Show where we just revealed our latest automotive aftermarket crate engine, the SB4 7.0. The 32-Valve DOHC V-8 was designed, developed and manufactured in-house.
The naturally aspirated, 7.0 Liter engine features Mercury Racing’s exclusive aluminum four valve cylinder heads and dual overhead camshaft valve train integrated with a LS cylinder block packed with Mercury Racing designed and specified hardware.
This proven valve train, which greatly enhances engine durability over a standard two-valve design, enables the engine to produce a staggering 750 horsepower at 8000 RPM on pump fuel!
Benefits of the DOHC four-valve design versus the typical LS pushrod layout include:
Improved intake and exhaust flow enables increased engine performance
Efficient, high tumble four valve combustion
Low mass, high stiffness design reduces stresses and enables smooth high RPM operation and long life
Improved drivability due to optimized camshaft timing at comparable horsepower levels
Mercury Racing is unique in the high performance powertrain business in that we design and develop fully integrated systems. We even go as far as developing our own electrical and engine management systems. Our proprietary powertrain control module, featuring internally written software, provides the opportunity for customization and application specific needs.
The Mercury Racing SB4 7.0 was developed utilizing 3D simulations and analyses on airflow, cooling, fuel and lubrication systems. Intense finite element analysis (FEA) studies were conducted on the head, block and rotating components to ensure an efficient and reliable powertrain.
Prototype testing is where the rubber meets the road. Mercury Racing conducts fired engine, motored engine, and dynamic rig testing. Tests are conducted to calibrate engine management systems, evaluate in-cylinder combustion, and measure timing drive dynamics and torsional excitation, just to name a few. Mercury Racing people, capabilities, and facilities are recognized through ISO 9000 and EU RCD certifications.

The Ultima is flanked with two SB4 7.0 static displays, one fully dressed and one cutaway to reveal exclusive features. A fully dressed SB4 7.0 is also displayed in SEMA’s New Product Showcase, also in the Upper Show Hall. Edelbrock, booth #22643 Central Hall, is displaying the SB4 cylinder head they cast for us.
We are proud to display one of SpeedKore’s most popular builds to showcase our potent QC4 1650 crate engine. Deemed TANTRUM, the 1970 Dodge Charger earned a Gran Turismo award for best domestic build at SEMA last year. Speedkore’s impeccable carbon fiber work, featured throughout the car, was one of many unique highlights that caught the attention of the judges and media alike.
From there – the car was sent to Los Angeles for multiple photo sessions and video shoots – culminating with a feature on Jay Leno’s Garage. Timing is everything. Shortly after the Leno show – the Mercury Racing powered Charger was requested for filming of the next movie in the Fast & Furious franchise. TANTRUM will be seen in the upcoming Fast and Furious film – Fast8. In US theaters April 14, 2017
Jay Leno has the opportunity to get behind the wheel of the most powerful and exotic cars money can buy in his show “Jay Leno’s Garage”, causing feelings of envy and desire among his viewers. The former “Tonight Show” host has turned his passion for cars into the popular web series, which gives a detailed look at the newest European supercars to great American classics.
One of the classics recently featured was a 1970 Dodge Charger, built by our friends at SpeedKore in Port Washington, Wisconsin. The “Tantrum” Charger is the first automotive application of Mercury Racing’s QC4 platform and based on its performance, it surely won’t be the last.
Mercury Racing launched the QC4 platform in 2010 as a high-performance offshore marine engine capable of exceeding the demands of the grueling racing environment. This modern powerplant features dual overhead cam (DOHC) 32-valve heads on top of a 9.0 liter aluminum block. The massive air flow of the heads is increased even further by two 94-mm turbo chargers, delivering upwards of 1650 horsepower on race fuel. After years of success as both a marine racing and pleasure engine, the team at Mercury Racing decided it was time to develop something car guys would crave.
While showing the automotive world our engineering prowess at SEMA, we also laid the foundation for the Tantrum by meeting Dave Salvaggio, builder of the Charger. After nearly two years of working together, the completed Charger was first displayed at SEMA 2015. After winning a Grand Turismo design award at SEMA, the Charger headed further west so the comedian could climb behind the wheel.
Leno was rightfully blown away at the beauty and performance of the QC4 engine, and perhaps a bit humbled by its full potential (It’s not often he relinquishes the key for the show’s customary burnout). The QC4 hits all the right notes for a modern crate engine for high end car builders. It is unique, modern, reliable, attractive and most importantly it provides an answer to every car guy’s visceral desire for more power.
Watch the Jay Leno’s Garage episode below to learn more about the QC4 powered Tantrum and see the QC4 in action on the California roadways.
The aluminum four valve head dual overhead camshaft valve train, designed and developed to integrate with General Motors LS series hardware, provides improved performance and durability versus a standard two-valve design.
