7.90 SECONDS @ 175MPH! THE 2400LB PLYMOUTH ARROW DOORSLAMMER GAPPING THE COMPETITION

Step into the staging lanes and leave your modern street car ego at the gate. If you think your bolt-on Hellcat or E85-tuned Redeye is the pinnacle of performance, you are about to get a brutal reality check. You are looking at the "Nitro Express," a 1979 Plymouth Arrow that has been completely transformed into a 7.90-second quarter-mile weapon. In an era where the automotive world is hyper-focused on plug-and-play HP Tuners software and heavy street cars, this dedicated Canada West Coast Doorslammer stands as a mechanical reminder of what pure, unadulterated drag racing actually looks like.
While the modern street scene spends endless hours arguing over 1000WHP dyno numbers and 60-130mph roll race outcomes, this tube-chassis monster is out here trapping a blistering 175 MPH at the drag strip. This is not a luxury coupe with a Whipple supercharger thrown on top; it is a purpose-built, 2,400-pound precision instrument designed for absolute violence on a prepped surface.
To truly understand the dominance of this Plymouth Arrow drag car, you have to look beneath the flawless black paint that was buffed just days before its debut at the Toronto Motorama. It utilizes a full custom chromoly tube chassis, shedding every single ounce of unnecessary street weight. Step inside, and you will not find any plush SRT Trackhawk leather or infotainment screens. You are met with a completely bare, all-aluminum cockpit built specifically to protect the driver when this machine is hurtling down TMP Cayuga or St. Thomas Dragway at 175 MPH.
When a vehicle is this incredibly light, managing high-speed stability becomes a life-or-death engineering challenge. To combat front-end lift and keep the car tracking perfectly straight, the front steel fenders have been drastically extended by a full eight inches. Aerodynamics dictate everything in the 7-second doorslammer class. The original door handles were shaved and replaced with recessed, flat Challenger-style handles to maintain a perfectly smooth side profile. Looking at the rear of the car, you will notice rare, factory-style aluminum louvers leading down to a massive structural rear wing. This wing generates immense aerodynamic downforce—roughly 350 lbs of it—locking the massive rear Mickey Thompson slicks directly to the track surface. To further optimize the vehicle's launch dynamics, the alcohol fuel cell is mounted at the very front of the chassis, ensuring perfect weight transfer when the car hits the drag strip prep and launches off the line.
Now, we have to address the mechanical heartbeat of this Plymouth drag car, and it is a specification that will undoubtedly trigger the brand loyalists. Resting between those front tube rails is a heavily fortified 383 cubic-inch Small Block Chevy. In the cutthroat world of 7.90 class racing, purist mentality takes a backseat to extreme reliability and proven power. Handling the massive boost is a Weiand 8-71 blower, topped by a mechanical fuel injection system constantly feeding high-octane alcohol into the motor.
Transferring that blown V8 power to the ground requires a drivetrain that is completely bulletproof. The 383 SBC is paired with a Chevy 2-speed Powerglide transmission. This setup allows the driver to build maximum boost at the starting line before violently releasing the power to a heavy-duty 9-inch Ford rear end. When the driver lets off that trans brake, the side-dump zoomies scream as the car rips past the 60-foot mark, delivering an exhaust note that rattles the grandstands.
We cover a lot of fast vehicles on the Mopar Bro network, from sub-9-second E85 Demons to heavily modified modern muscle cars. But there is a visceral, terrifying level of respect demanded by a classic doorslammer that relies on a blower drive ratio rather than a laptop to gap the competition.
