The Beginning: From Trash to Treasure

The story of this remarkable Foxbody Mustang begins with its humble origins. Dion, the owner, acquired the car from his cousin for a mere $400. It was far from perfect, with a damaged front end and extensive bodywork needed. However, Dion saw potential in the car and decided to take on the challenge of restoring it to its former glory.

Motivated by his passion for Mustangs and a desire to create something special, Dion dedicated countless hours to transforming the Foxbody Mustang. With unwavering determination, he updated the front end to a 1991 model, along with refreshing the interior to match. Taking matters into his own hands, Dion and his brother worked tirelessly, turning their garage into a hub of creativity and craftsmanship. Their hands-on approach ensured that every modification and improvement was done to their exacting standards.

Engine Power: Unleashing the Beast

Under the hood of this Foxbody Mustang lies a small block 440 engine, which Dion sourced from a 351 Windsor. This engine setup defied the skeptics who believed that a 351 couldn’t be bored out to a 440. Dion’s custom build and expertise with carburetors proved them wrong. The result? An astonishing 700 horsepower at the rear wheels. This Mustang’s engine is a testament to Dion’s meticulous tuning and skillful modifications, solidifying its reputation as a true Hellcat killer.

To achieve such impressive power, Dion left no stone unturned. He fine-tuned every aspect of the engine, ensuring optimal performance and relentless acceleration. From the choice of components to the careful calibration of the carburetor, each detail was carefully considered. Dion’s passion for horsepower and his pursuit of perfection drove him to create an engine that delivers unrivaled performance on the road. This Foxbody Mustang stands as a testament to his dedication and expertise, leaving all doubters in its dust.

Handling and Brakes: Keeping It Under Control

To harness the immense power of the engine, Dion made several upgrades to the chassis and suspension. The car features subframe connectors, a tubular subframe in the front, and tubular control arms. These enhancements improve rigidity and enhance handling characteristics. Furthermore, a Tremec TKO600 transmission and 8.8 rear end with 35-spline axles ensure power is delivered smoothly to the ground.

Braking upgrades were made as well, with Cobra brakes installed in the front. Surprisingly, the rear still retains drum brakes, but they work well for the setup. Despite the car’s weight distribution, Dion managed to achieve reliable braking performance, even with a high-lift cam.

Aesthetic Upgrades: Standing Out from the Crowd

In addition to its jaw-dropping performance, this Foxbody Mustang also boasts a striking visual presence. Dion’s attention to detail extended beyond the engine bay, as he sought to create a car that would turn heads wherever it went. With carefully selected aesthetic upgrades, this Mustang stands out from the crowd in every way.

One of the most notable visual enhancements is the custom hood with its imposing scoop. While it adds a fierce and aggressive look to the car, it serves a functional purpose as well. The engine’s elevated position necessitated a larger scoop to provide sufficient clearance and optimize airflow. Dion’s decision to go big paid off, resulting in a design that is both eye-catching and practical.

Another notable upgrade is the choice of wheels. Dion opted for Weld V-Series and Pro Star wheels, finished in a vibrant orange color. These wheels not only provide a striking contrast against the car’s teal exterior, but they also feature a true bead lock system. This ensures that the tires stay firmly in place, even under the immense power and torque unleashed by the engine.

To complete the aesthetic transformation, Dion incorporated a host of other modifications, including subframe connectors, tubular control arms, and a manual rack. The interior received a makeover as well, featuring a Dakota Digital dash and other elements sourced from a 1990 Mustang. Every upgrade was carefully selected to enhance both the performance and visual appeal of this Foxbody Mustang, resulting in a truly remarkable and head-turning creation.

With its impressive performance and striking aesthetic upgrades, this Foxbody Mustang stands as a testament to Dion’s commitment to creating a one-of-a-kind vehicle. Whether it’s the growl of the engine, the boldness of the custom hood, or the attention to detail evident in every aspect of the car, this Mustang demands attention and admiration. It’s a true reflection of Dion’s passion for muscle cars and his unwavering dedication to crafting a masterpiece that stands out from the crowd.

The Test Drive: Unleashing 700 Horses

With all the modifications and upgrades in place, it was time to hit the road and experience the full potential of this beastly machine. Dion uses the Mustang as a daily driver, commuting from Inglewood to Disneyland and even taking longer trips to Fontana and San Bernardino. The power delivery of the engine, combined with the low-end grunt from the 4.10 rear gears, provides an exhilarating driving experience.

During a test drive captured in the YouTube video, Dion showcases the car’s acceleration and impressive speed. The Foxbody Mustang effortlessly leaves modern muscle cars in its dust, surprising even the most powerful challengers. The exhaust emits a growl that commands attention, further amplifying the adrenaline rush.


The 700HP all-motor Foxbody Mustang featured in the YouTube video is a testament to the dedication and passion of its owner, Dion.
