Dodge Dart 1967 – Street Outlaws DOMINATOR

For years the Dominator Dart made its reputation on a nitrous-fed Hemi, exactly the way street racing reputations were traditionally built. Then Joe Woods tore the whole combination out and replaced it with a 632-cubic-inch big block Chevrolet and a pair of 88mm turbochargers. In a Mopar. Read on for why a die-hard Dodge racer walked away from the setup that made his name, and what a 1967 A-body brings to the fight.

Street racing has always been an argument about what works, settled in eighth-mile increments on closed-off industrial roads, and the cars that win those arguments rarely stay the same for long. One of the more recognizable Mopars on the scene spent years building its reputation on a nitrous-fed Hemi — the traditional combination, the one that made grudge racers famous long before television crews showed up with cameras and contracts. Then the whole thing came out. What replaced it was not a bigger Hemi or a better bottle setup, but a completely different philosophy of making power, wearing a badge from an entirely different manufacturer. That decision tells you almost everything about where the sport went.

Why an A-Body in the First Place

The 1967 Dodge Dart is a deeply logical choice for this kind of build, and the reasons are structural rather than sentimental. Chrysler’s A-body rode a 111-inch wheelbase and carried a curb weight that started around three thousand pounds — light for anything with a full steel body and a back seat. The engine bay is unusually accommodating for the car’s exterior size, the unibody responds well to a properly triangulated cage, and the rear frame rails sit where a serious suspension can be attached to them. Small, light, and structurally cooperative is the whole specification list for a grudge car, and the Dart checks every box.

The Factory Precedent: Hemi Darts in 1968

There is factory precedent for exactly this idea. In 1968, Chrysler built a run of about eighty Hurst-prepared Hemi Darts specifically for Super Stock drag racing — acid-dipped panels, fiberglass front ends, lightweight glass, no sound deadening, no back seat, and a 426 race Hemi crammed into a car that had never been designed to hold one. They were sold with a disclaimer stating they were not intended for street use. Those cars established the template that grudge racers have been following ever since: take the smallest available body, install the largest available engine, and worry about the consequences later.

Dominator on the 405

Dominator built its name on Oklahoma City’s street racing scene, the one that Street Outlaws made nationally famous when it premiered in 2013 and turned a local list of the fastest cars into appointment television. The show’s format — a ranked list, challenged from the bottom up, raced on real streets — created enormous pressure toward consistency. It is one thing to make a monstrous pass on a perfect night. It is another to be called out repeatedly across a season and be expected to deliver every single time, on varying surfaces, in varying weather, with a camera crew waiting.

What the Nitrous Combination Actually Did

That pressure is precisely what killed the nitrous combination. Nitrous oxide delivers a huge, instant power increase for very little hardware cost, which is why it dominated street racing for decades. But it arrives all at once, it changes the engine’s fuel and timing requirements dramatically the moment it activates, and it is unforgiving of a tune that is even slightly off. Bottle pressure varies with temperature. Solenoids fail. A lean condition at full song will destroy pistons in a single pass. It made legends, and it also ended a great many seasons in a cloud of smoke.

The Case for Boost Over Bottles

Turbochargers changed the calculation. Boost builds progressively rather than arriving as a step function, which makes the car far easier to launch and far kinder to parts. Modern electronic engine management lets a tuner adjust boost by gear, by time, and by driveshaft speed, effectively shaping the entire power curve to match available traction. Data logging turns each pass into information rather than anecdote. The result is a car that repeats its performance run after run, which in a format built around repeated challenges matters more than a single spectacular number.

632 Cubic Inches of Big Block Chevrolet

The new combination centers on a 632-cubic-inch big-block Chevrolet built by Troy Scott Race Engines, paired with twin 88-millimeter Turbonetics turbochargers. The displacement figure is worth pausing on: 632 cubic inches is more than ten liters, achieved through an aftermarket block with a bore and stroke far beyond anything Chevrolet ever produced, running billet or forged rotating components throughout. Naturally aspirated, an engine like that already makes enormous power. Add a pair of turbochargers of that size and the ceiling moves into territory where the limiting factor stops being the engine and becomes the chassis, the tire, and the driver’s nerve.

Fitting Twin 88s Into a 1967 Engine Bay

Physically installing that package in a 1967 A-body is its own engineering exercise. A pair of 88mm turbos and their associated hot-side plumbing take up more space than the original slant six occupied in its entirety, and everything has to route around a steering box, a firewall, and a driver who needs somewhere to put his feet. Intercooling, wastegate placement, exhaust routing away from anything that melts, and oil feed and drain lines for both turbochargers all have to coexist in a bay designed in the mid-sixties. Builds like this are as much fabrication projects as engine projects.

The Chassis Underneath All of It

Then there is everything behind the engine. Power at this level requires a full chromoly cage tying the front and rear structure together, a four-link rear suspension with adjustable instant center, a properly built transmission and converter matched to the boost curve, and brakes that can stop the car from well over one hundred fifty miles per hour on a surface with no runoff. The suspension tuning is arguably harder than the engine work, because everything depends on transferring weight to the tire at exactly the right rate — too fast and it spins, too slow and it never hooks at all.

Badge Loyalty Versus the Time Slip

The part that generates the most argument has nothing to do with engineering. Putting a big-block Chevrolet in a Dodge is heresy in most garages, and grudge racing is a culture where brand loyalty runs genuinely deep. The counterargument is simple and difficult to refute: the big-block Chevy has the widest aftermarket support of any American racing engine, the largest selection of blocks, heads, and rotating assemblies, and the deepest pool of accumulated knowledge about making enormous power reliably. On the street, the time slip does not record what badge was on the valve covers. That a 1967 Dart built for a completely different era of racing can still run at the front is the more remarkable fact anyway.
