In this article, we’ll take a closer look at this incredible machine, its specifications, and what makes it truly unique.

The Story behind the Name

Every car has a story, and “Sexy Sally” is no exception. The name originated when the car’s owner, Sean, was asked why he chose such a unique name. It turns out that his wife initially referred to the car as “Sexy Salad” in reference to its Super Sport (SS) model. Over time, the name stuck and evolved into “Sexy Sally.” It’s a playful and memorable name that perfectly suits this extraordinary machine.

Beyond its name, “Sexy Sally” has a captivating history. Sean purchased the car as a young adult, fulfilling a lifelong dream of owning a powerful and stylish vehicle.

With every drive, Sean felt an exhilarating sense of freedom and joy. The car became an integral part of his life, accompanying him on memorable road trips and unforgettable adventures. Its story is a testament to the deep connection between car enthusiasts and their beloved machines, and “Sexy Sally” continues to inspire and evoke admiration wherever she goes.

Design and Modifications

To achieve its incredible performance, “Sexy Sally” underwent significant modifications. The car’s frame went through a complete transformation, with careful cutting and rebuilding to accommodate the massive rear tires. The rear section was back-halved, allowing for the installation of larger tires and ensuring optimal traction on the road. This modification not only improved the car’s performance but also gave it a distinct and aggressive look.

In addition to the frame modifications, several upgrades were made to enhance the car’s handling and stability. The factory suspension was replaced with two-inch drop spindles, which lowered the car’s center of gravity and improved its overall handling. Competition drag shocks were also installed to provide precise control and damping, ensuring a smooth and stable ride even at high speeds. These suspension upgrades contributed to “Sexy Sally’s” exceptional performance on the road and helped make every drive a thrilling experience.

The modifications made to “Sexy Sally” not only transformed its appearance but also optimized its performance. The meticulous attention to detail and the choice of high-performance components resulted in a car that stood out both on the streets and the race track. From its custom frame modifications to the upgraded suspension, “Sexy Sally” became a machine that could turn heads and deliver an exhilarating driving experience. It’s a testament to the dedication and passion of car enthusiasts like Sean, who go to great lengths to create their dream cars and push the boundaries of performance.

Powerhouse Engine

At the heart of “Sexy Sally” lies a monstrous power plant. The engine is a 565-cubic-inch Dart Big M block, equipped with Dart Pro 1 heads, a Scat crank, and a bullet custom ground cam. This impressive combination of high-performance components ensures the engine’s durability and power output. To handle the immense power generated by the car, the entire engine is forged, providing strength and reliability under extreme conditions.

One of the standout features of “Sexy Sally’s” engine is the nitrous system. When engaged, the nitrous oxide injection system adds an extra boost of power, pushing the engine to its limits. With the nitrous activated, the engine unleashes over 1200 horsepower, transforming “Sexy Sally” into an unstoppable force on the drag strip. The combination of the meticulously built engine and the nitrous system creates an adrenaline-pumping experience for both the driver and anyone lucky enough to witness the car’s incredible acceleration.

The Thunderous Exhaust

A car of this magnitude deserves an equally impressive exhaust system, and “Sexy Sally” does not disappoint. One of the standout features is the meticulously crafted Lemons headers. Each tube and flange of the headers has been designed with precision to optimize performance. This careful attention to detail ensures that the exhaust gases flow smoothly, minimizing restrictions and maximizing the engine’s power output.

The impact of the exhaust system goes beyond performance. When “Sexy Sally” comes to life, the unmistakable roar of the engine fills the air, commanding attention and leaving an indelible impression. What sets this car apart is the absence of mufflers, allowing the engine’s full sound to be unleashed. This decision amplifies the raw power and exhilarating soundtrack of the engine, captivating all who have the pleasure of hearing it.

The combination of Lemons headers and the absence of mufflers in “Sexy Sally” creates a symphony of engine notes that are as impressive as the car itself. The roaring exhaust not only adds to the overall performance but also becomes an auditory signature, leaving no doubt that this machine means business. Whether on the streets or at the race track, the thunderous sound of “Sexy Sally’s” exhaust is an integral part of the car’s personality, announcing its presence with every rev and ensuring that it will never be forgotten.

Suspension and Tires

Despite its aggressive appearance, “Sexy Sally” retains the factory stock A-arms, albeit with two-inch drop spindles and drag shocks. These modifications work together to enhance the car’s performance and handling. The two-inch drop spindles lower the car’s center of gravity, improving stability during acceleration and cornering.

The drag shocks provide additional control, ensuring that the car remains firmly planted on the ground, even under high-speed conditions. By retaining the factory stock A-arms, the car maintains its original design while benefiting from the added performance upgrades.

One of the most striking features of “Sexy Sally” is the colossal tires adorning the rear wheels. Mickey Thompson tires are chosen for their exceptional size and performance. These massive tires measure a staggering 33 inches in height and 22 inches in width, mounted on 15-inch wheels. The substantial width and height of these tires not only contribute to the car’s imposing appearance but also provide exceptional traction and grip on the road. Such impressive tire dimensions give “Sexy Sally” an advantage in launching off the line and maintaining control during high-speed maneuvers.

The combination of the factory stock A-arms, two-inch drop spindles, drag shocks, and the colossal Mickey Thompson tires makes “Sexy Sally” a force to be reckoned with. These modifications ensure stability, control, and optimal performance, allowing the car to effectively harness its immense power. Whether tearing up the drag strip or cruising down the streets, “Sexy Sally” leaves an unforgettable impression with its aggressive stance and the sheer presence of its colossal rear tires. It’s a machine that demands attention and showcases the perfect blend of style and performance.

The Transmission and Shifting

Shifting gears in “Sexy Sally” is an experience unlike any other. The car is equipped with an FTI Stage 5 reverse-pattern manual valve body transmission. This custom-built transmission is specifically designed to handle the immense power generated by the car’s engine, capable of supporting up to 2000 horsepower. Unlike traditional automatic transmissions, the FTI Stage 5 requires manual shifting, putting the driver in complete control of gear changes.

The reverse-pattern design of the transmission adds to the uniqueness of the driving experience. Instead of the conventional “P-R-N-D” pattern, the reverse-pattern transmission is configured as “P-R-N-1-2-3.” This arrangement allows for quicker and more precise gear changes, particularly beneficial during high-performance driving scenarios. The driver can select gears directly, ensuring optimum performance and maximizing the engine’s power delivery.

With the FTI Stage 5 reverse-pattern manual valve body transmission, “Sexy Sally” offers a true driver-focused experience. The manual shifting capability allows enthusiasts to fully engage with the car and tailor gear changes to their driving style. It adds an extra layer of excitement and involvement, putting the power and performance of “Sexy Sally” directly in the hands of the driver.

Reinforced Rear End

To withstand the immense power being transmitted to the rear wheels, Sexy Sally is equipped with a reinforced 12-bolt rear end. This setup, coupled with 411 gears and a Wave Track posi differential, ensures that power is efficiently transferred to the ground without any hiccups.

Safety is of paramount importance in a car as potent as Sexy Sally. The car features a fully certified NHRA eight-and-a-half-second chassis, providing structural integrity and protection for the driver. The interior maintains some factory elements, including the door panels and console, while a carbon fiber dash with automated gauges adds a modern touch.

Interior Upgrades

While the primary focus of “Sexy Sally” is on performance, it doesn’t compromise on providing a comfortable and stylish interior. The cabin showcases a blend of factory elements and custom enhancements. The door panels have been retained, although with repositioned armrests to accommodate the presence of a roll cage. This modification ensures that both safety and comfort are taken into account.

To add a touch of sophistication, the factory console has been customized to match the car’s aggressive aesthetic. The console upgrade enhances the overall visual appeal of the interior while maintaining functionality. Additionally, a carbon fiber dash with automated gauges replaces the original, providing a modern and high-tech feel. The carbon fiber material not only exudes a sense of luxury but also offers lightweight durability.

The combination of factory and custom elements in “Sexy Sally’s” interior creates a unique and well-balanced atmosphere. The retention of certain factory components preserves the car’s heritage and familiarity, while the customized features add a touch of personalization and modernity. This thoughtful interior design ensures that the driver and passengers can enjoy a comfortable and visually appealing space, even during high-performance drives.

In the pursuit of performance, “Sexy Sally” proves that it’s possible to have both power and creature comforts. The interior modifications enhance the overall driving experience, providing a stylish and comfortable environment that complements the car’s exceptional performance capabilities.
