Street-Legal NASCAR War Machine

This isn't a clone.
This isn't a tribute.
This is a real-deal 2020 NASCAR Gen 6 stock car with war stories — now legally stalking public roads.

A genuine Roush Fenway Racing Chassis #RK-1140, built June 2020. The same chassis that carried #17 Chris Buescher into battle across multiple NASCAR tracks in 2020 and 2021. After retirement in 2022, it landed at Rusty Wallace Racing, where it was reborn in the sinister “Midnight” #2 livery and used for high-dollar, once-in-a-lifetime track experiences — personally driven by Rusty himself. Last documented outing? Circuit of the Americas, Texas.

Now here's where it gets unhinged.

The NASCAR chassis was professionally welded to the legally registered chassis components of a 1999 Tube Frame Special Construction vehicle. Result? A street-legal 1999 Missouri Historic Vehicle. That means lower personal property tax and zero safety or emissions inspection requirements.

Yes.
A 600hp NASCAR weapon.
Street titled.

The Hardware

Under the hood sits a Rusty Wallace Racing–built GM604 aluminum head crate motor punching out approximately 600 horsepower. Fed by a brand-new Holley Aluminum Street HP 750 CFM carburetor. It doesn't purr — it detonates.

Backing it is the original NASCAR Mid Valley Racing Transmissions 4-speed manual, straight-cut gears, completely rebuilt in 2025. The sound alone is mechanical violence. Out back? The original NASCAR 9-inch rear end.

This is not softened. It's not diluted. It's barely domesticated.

Cockpit: Pure Race DNA

Inside is all business:

• Carbon fiber dash
• AutoMeter Pro Comp Ultra-Lite gauges
• GPS speedometer/odometer
• ISP full containment seats
• Window nets (driver AND passenger)
• Fully functional fire suppression system

You don't sit in this car. You strap into it.

But it's been made street capable without losing its edge:

• LED headlights, fog lights, blinkers, taillights
• Bluetooth sound system
• New windshield
• Battery relocated to the trunk to power air ride, lights, and stereo
• New fuel cell with sending unit and gauge

Suspension & Setup

Currently dialed for road courses — this one turns left and right.

It runs separate front and rear air-ride systems for on-the-fly ride height adjustment. Slam it. Lift it. Tune the stance as needed. Included with the sale are the original Penske NASCAR shocks for purists who want to take it back to full track trim.

All safety aero flaps remain functional.

Fresh Fluids – Ready to Rip

Serviced within the last 40 miles:

• Valvoline VR1 20W-50 engine oil
• Mobil 1 75W-90 transmission fluid
• Mobil 1 75W-90 rear gear oil

It's not sitting. It's ready.

What This Really Is

This is a former top-tier NASCAR chassis with documented race history.
Driven by Chris Buescher.
Piloted by Rusty Wallace.
Reborn as a street-legal, Missouri Historic titled monster
.
It's loud. It's raw. It doesn't care about comfort.
And it sure as hell doesn't blend in.

You don't buy this to cruise quietly.
You buy this because subtlety is for stock vehicles.
