Engine and Performance
The turbocharged 3.8-liter V6 incorporates a GN1 Performance long-rod stroker kit, creating the foundation for this modified powertrain. A triple-ball-bearing turbocharger works with a Super Extreme intercooler, Aeromotive 340 fuel-pump regulator, and upgraded cooling components. Exhaust gases pass through a Flowmaster FX Series muffler, adding another aftermarket component to the engine’s supporting systems. Power is managed by a rebuilt four-speed automatic transmission connected to an Art Carr nine-inch torque converter.
Engineering and Specifications
Aldan American adjustable coilovers are installed front and rear with an upper shock-mount reinforcement bar, while Hotchkis Racing upper control arms further modify the chassis. A four-wheel Baer disc-brake conversion uses a one-inch-bore primary cylinder to support the upgraded braking arrangement. Service performed during 2021 reportedly included replacement bushings, ball joints, steering components, tie rods, and brake lines.
Design and Heritage
Repainted black bodywork preserves the monochromatic visual identity closely associated with the Grand National while presenting the car in a refreshed finish. Weld Racing wheels feature black spokes and chrome lips, creating a strong contrast against the dark body and introducing a more contemporary stance. A sunroof remains part of the exterior configuration, providing an additional opening above the comprehensively revised passenger compartment.
Driving Experience
Black and Sand Gray cloth upholstery creates a two-tone cabin centered around the replacement New Vintage USA instrument display. A Pioneer touchscreen stereo and DS18 sound system add modern entertainment controls and expanded audio capability to the interior. The stroker engine, upgraded turbocharger, specialized cooling, rebuilt transmission, adjustable suspension, wide Pirelli tires, and Baer brakes create an experience shaped by extensive performance modifications.
