The 1970 Chevelle is an iconic muscle car known for its powerful performance and classic design. However, imagine coming across a 1970 Chevelle that defies expectations. Meet Alex’s 1970 Chevelle powered by a twin-turbo diesel Duramax engine, generating a staggering 1100 ft-lbs of torque. In this essay, we’ll explore the fascinating features and characteristics of this extraordinary vehicle.
Unveiling the Unconventional: At first glance, this ’70 Chevelle may resemble a typical big block Chevelle, but it’s far from ordinary. Alex, the owner, shares that he purchased the car as-is, with only a few modifications made, such as installing coilovers for desired ride height. The original owner, Mike, who operates the Muscle Factory, a Chevelle parts shop, had built this Chevelle with an LBZ Duramax engine sourced from an ’06 Silverado HD. To handle the immense power, a GeForce 5r manual transmission was installed.
The Powerhouse
The LBZ Duramax engine delivers 650 horsepower and an astonishing 1100 ft-lbs of torque. What’s more impressive is that this diesel-powered Chevelle achieves an impressive fuel efficiency of 30 to 33 miles per gallon. Cruising at 90 miles per hour in fifth gear, the engine operates at a mere 1200-1300 RPM with zero boost. The power delivery is unique, requiring some adjustment due to the immediate torque response upon clutch release.
The Allure of a Vintage Build: Although Alex initially considered flipping the car, he developed an affinity for it due to its uniqueness and vintage appeal. The car was built in 2013, featuring a frame-off restoration with various new components. While it may show signs of aging in the paintwork, the overall condition remains excellent, with only 500 miles on the odometer.
Enhancements for Performance
While the Chevelle retains its stock chassis, some modifications were necessary to accommodate the diesel powerplant. Additional bracing and a custom shortened oil pan with a skid plate were installed for clearance and protection.
The suspension features all-American components, including coilovers and ABS electronic brakes. To handle the tremendous torque, a Chris Austin Fab nine rear end was added, ensuring optimal traction and durability.
Aesthetics and Presence
Visually, this Chevelle maintains its classic appeal. It sports a sleek black exterior with white stripes, complemented by chrome accents and a lowered stance. The wheels, 18×10 inches at the front and 18×11.5 inches at the rear, are forged lines. The aggressive tire setup includes 315s in the rear and 275s up front, providing ample grip to handle the power.
Preserving the Original Character
One aspect that distinguishes this build is the preservation of the Chevelle’s original aesthetics. The interior retains its stock SS layout, aside from a digital diesel monitor. The shifter remains true to the Chevelle’s heritage, reinforcing the nostalgic feel of the car. Alex appreciates the decision of the original builder to maintain the classic appearance while infusing it with an incredibly powerful engine.
Conclusion
Alex’s 1970 Chevelle is a fusion of vintage aesthetics and modern performance. Powered by a twin-turbo diesel Duramax engine, it challenges norms and showcases alternative powerplants in classic cars. With 650 horsepower and impressive fuel efficiency, this Chevelle offers a unique blend of nostalgia and power. Upgraded suspension, brakes, and rear end enhance its performance capabilities. It stands as a testament to passion and creativity, inspiring others to explore new avenues in car customization.
