Troy LaCrone’s Approach to 7.90’s with a Street-Driven Camaro

Troy LaCrone made his name with a nitrous small-block 1971 Camaro that ran 9.19 at over 140 mph while still riding on leaf springs and slapper bars, a car that looked eight seconds slower than it was. Asked whether he would keep chasing quicker numbers, he said he hoped not. He later posted a 7.7730 average at Hot Rod Drag Week and beat JJ Da Boss on television. Read on for how that progression actually happened.

A 1971 Camaro riding on leaf springs and slapper bars has no business running nine seconds in the quarter mile. That combination belongs on a weekend cruiser, not on a car trapping north of 140 mph, and yet that is precisely what Troy LaCrone built and ran, a nitrous small-block machine that looked about eight seconds slower than it actually was. Asked at the time whether he would keep chasing quicker numbers after breaking into the nines, he answered with a flat two words: I hope not. Drag racing has never once let anybody keep that promise, and it did not make an exception here.

The Sleeper That Started the Whole Thing

The car that first put LaCrone in print was a nitrous-fed small-block 1971 Camaro that eventually ran 9.19 at over 140 mph, a number he coaxed out of a chassis still using leaf springs and slapper traction bars. The whole appeal was the mismatch. It presented like a tidy twelve-second street car, the sort of thing that pulls into a cruise night and gets polite nods, and then it went down the track quick enough to make people check the scoreboard twice. That gap between appearance and elapsed time is the oldest currency in street racing, and this car had it in abundance.

Why Nines on Leaf Springs Is So Hard

Anyone who has tried to make serious power work through a stock-style leaf spring rear end understands why that 9.19 raises eyebrows. Leaf springs allow axle wrap under load, which sets up wheel hop and destroys the consistency a quick car needs, and slapper bars are the crudest available fix. They work by slapping against the spring to limit rotation, which is effective enough for a strong street car and increasingly marginal as power climbs. Most builders chasing single-digit passes abandon the setup entirely for a ladder bar or four-link arrangement, which is exactly what makes doing it the hard way notable.

The Expensive Detour Through Turbocharged Mustangs

LaCrone eventually sold the Camaro and moved on to a pair of late-model turbocharged Mustangs, a direction that looked obvious on paper and delivered far less than expected. He later described those attempts as unrewarding for various and expensive reasons, which is racer shorthand for a lot of money spent learning what does not work. Plenty of people quit at that point. The more useful reading is that the detour clarified what he actually wanted, which was not the fastest available platform but a car he could drive to a track, run hard, and drive home again.

What Drag Week Actually Demands of a Car

Hot Rod Drag Week is the event that separates street-driven claims from street-driven cars. Competitors run at five different tracks across five consecutive days and drive roughly a thousand miles of public road between them, carrying every tool, spare part, and gallon of fuel with them. There is no chase truck full of parts, no trailer, and no skipping a day. The winner is decided on the average elapsed time across all five days, which means a single spectacular pass counts for nothing if the car breaks on Wednesday or the tune goes soft when the weather turns.

A 7.77 Average and What That Number Means

Against that format, the 7.7730 average LaCrone posted in 2018 is the headline figure. Averaging in the seven-second range across an entire week places a car in genuinely rarefied company. For scale, Larry Larson recorded the first six-second Drag Week average in 2015 and Tom Bailey broke into the fives in 2019, and both were considered milestone achievements in the sport. Everything below eight seconds on that event represents a purpose-built machine that still has to survive several hundred miles of interstate between rounds without a support crew rebuilding it overnight.

One Quick Pass Versus a Quick Week

The distinction between running one quick pass and running quick all week is the entire difficulty of the discipline. Track surfaces change between venues, air density swings with weather across a week in September, and every component in the car accumulates damage that nobody has time to properly diagnose between the finish line and the next town. Tuners on this circuit spend their evenings in motel parking lots making decisions with flashlights. Consistency at that level is less about peak horsepower than about building a combination that tolerates being run hard, repeatedly, without a fresh engine waiting in a trailer.

Memphis, No-Prep, and Racing on Somebody Else’s Terms

LaCrone’s profile grew further through an appearance on the Memphis edition of the Street Outlaws franchise, where he beat Lee Roberts before going on to take down JJ Da Boss, the driver whose crew effectively defines that series. Racing in that world means unprepped or lightly prepped surfaces, staged starts negotiated between drivers rather than dictated by a tree, and a tolerance for conditions that would be rejected outright at a national event. Winning there against established local names is a different credential than a timing slip, and it travels further among people who race on actual streets.

Street-Driven Is a Rules Term, Not a Brag

The phrase street-driven gets used loosely, but in competition it carries hard requirements: DOT-approved tires, working lights, a licence plate, and the ability to complete long road transits under the car’s own power. Safety rules scale with speed rather than with intent, and the national sanctioning bodies draw firm lines. A car quicker than 11.49 needs a roll bar, anything running below ten seconds needs a full cage, and beyond that come mandatory harnesses, window nets, driveshaft loops, and fire systems. A seven-second street car is therefore a caged, certified race car that also happens to hold a licence plate bracket.

The Camaro Body Nobody Expects to Be Fast

The second-generation Camaro body he started with is not the obvious choice for this kind of work. The 1970 through 1973 cars are heavy, long-doored, and comparatively soft in the shell next to the first-generation cars and Fox-body Mustangs that dominate grassroots drag racing. Builders pick them for looks and for the sheer surprise value rather than for any structural advantage, then spend real effort adding subframe connectors and cage tie-ins to make the chassis behave. Starting with the harder platform is part of why the early nine-second passes registered with people at all.

Chasing the Numbers You Swore You Would Not Chase

What makes the whole arc worth retelling is that the trajectory was entirely predictable to everyone except the man living it. A racer who has just run 9.19 in a car that looks like a cruiser does not stop, sell everything, and take up golf. He says he hopes not, then builds something faster, and then finds himself averaging in the sevens across five tracks in five days. The sport has a way of converting every finish line into a new starting point, and the people who chase it hardest are usually the ones who claimed they were already satisfied.
