Jean Aiton’s 1992 Fox-Body LX is Basically an 8-Second Renegade Street Car
Nothin’ Like A Nasty Fox-Body
The Mustang has been around for over five continuous decades, so when it comes to building that dream car, the possibilities are seemingly endless. For Jean Aiton, that dream car was built into an 8-second Fox-body street car. “I’ve been told it’s a Renegade car that I force on the street,” Jean says. “I built the car keeping the NMRA True Street class in mind, but more than anything I built it for my enjoyment and to remain a street car.
Jean, a Sergeant at the Huntsville Police Department, left no stone unturned in his search for his perfect Mustang build. Having owned different Mustangs along with several Fox-body Mustangs over the years, he researched many different generations and drivetrain combinations, but he kept coming back to that familiar Fox-body platform.
Jean stumbled across this 1992 Mustang LX on a local Craigslist ad back in 2011. The car was powered by a stock-block 347ci engine with a Vortech V-7 YS supercharger, Lunati Voodoo cam, 170cc Dart Pro 1 heads, a T5 transmission, and 3.73 gears. Exhaust flowed through 1-5/8 shorty headers, a 2.5-inch off-road mid-pipe, Dynomax mufflers and stock tailpipes.
He met the owner at Huntsville Dragway where he watched it make a 6.88-second run at 105 mph in the eighth-mile with easy launching and granny shifting. He knew the car made decent power and had potential despite its stock computer, Super FMU, heavy wheels, stock chassis and all factory suspension.
Originally the car was painted Deep Emerald Green but is now slathered in Jewel Green Metallic after the body shop used the wrong paint code for a 1993 Bronco. Heath Terry, owner of Southside Rods and Resto in Arab, Alabama, spent 50 hours wet-sanding and fixing the mistakes made by the previous painter.
Jean’s Fox is now powered by a Ford Racing A4 302-based 8.2-inch deck block bored and stroked to a 349ci with a compression ratio of 10:1. An Eagle 5.4 crank works in conjunction with Diamond pistons via Eagle H-rods and a custom grind on a Comp hydraulic-roller camshaft. The engine was built by Dale Meers Racing Engines in Buffalo, Kentucky.
Built by Ron Sharpe of Advanced Airflow Engineering, Trick Flow Specialties heads sit atop the engine with Twisted Wedge 225cc intake runners, and a Holley Systemax ported upper and lower manifold that was previously installed on Alton Clements’ championship NMRA Renegade car. Feeding the thirst are Holley 120 lb/hr fuel injectors. Titanium intake and exhaust valves that measure 2.08 and 1.60, and he installed Crower shaft mount rocker arms. Oil is pumped through a Melling oil pump, and a Milodon 7-quart rear sump pan seals the bottom end.
“The heads were ported for the NMRA Renegade class. They were formerly on Mike Post’s Renegade car,” Jean tells us. Extensive work on both the intake, exhaust ports and bowl work with a lot of attention paid to mid-lift flow. It features titanium retainers with 8-degree keepers and locks, 1.550-inch diameter dual springs on intake and exhaust with a damper. The Seat pressure is 150 lbs. and 440 lbs. open at .600-inch lift.
To really amp up the power, a Vortech V-7 YSi with a max of 28 psi is mated to a custom throttle-body and features a Vortech 50mm cog crank pulley; the upper cog pulley varies depending on running a street or race tune. A standalone Speed Density MAF helps keep things in check, and a Blowzilla blow off valve is mounted on the 4-inch intake pipe. With the Meziere 55gpm water pump, custom radiator and twin fans pushing 3,412 cfm, keeping cool in Alabama hasn’t been an issue.
“I stayed with a supercharger rather than a turbo for a couple of reasons. I have always enjoyed the sound of the supercharger and the exhaust with the more aggressive cam profile than a turbo combo. I enjoy the car being so aggressive sounding and that also fits the look of the car,” Jean explains.
Adding to the orchestra are 1 7/8-inch powder coated Hooker headers that flow down to a modified 3-inch X-pipe and Spintech Super Pro Street 9000 series mufflers.
Huges Performance from Phoenix, Arizona, built the Extreme Duty 4L80E with a fully manual valvebody and transbrake. It also features a PST steel driveshaft complete with a Stifflers safety loop, and a Derale cooler with a fan keeps everything at temp. The 4,000-stall helps launch the car along with a Custom PTC Billet lockable converter. “With the 4L80E I can enjoy even highway speeds because of the overdrive. With the ability to lock my converter, at 70mph in overdrive with the converter locked I’m only at 1,200 rpm’s,” Jean says. Shifting power is provided by a Kilduff Machine shifter with polished sticks, a powder coated knobs, and transbrake switch.
Ignition components consist of an MSD 7531 Digital 7 ignition box and billet low profile distributor with crank trigger, Ford Racing wires, HVC II race coil, and NGK plugs. The 200-amp one-wire alternator was previously used in Brian Mitchell’s championship NMRA Renegade car.
The suspension is backed Strange 10-way shocks in the front and rear, front 14-150 with coilovers, and rear QA1 10-350 springs. The Ford 8.8 rearend is stuffed with Ford Performance 3.73 gears and Moser 31-spline axles. Wolfe Racecraft adjustable rear upper and extensively modified lower control arms, with a Wolfe anti-roll bar and UPR k-member, and Wolfe travel limiters. The car also has Wolfe through the floor subframes, mini tubs, solid spherical bushings, and Wolfe adjustable spring perches welded in place to fine tune the ride height.
The H.O. Fibertrends 3-inch fiberglass cowl hood is held by MRT bolt-in hood struts. Scott Rod fab inner fender and frontend panels and strut tower panels are specially made in aluminum and smoked one-piece headlights grace the front.
Weld Magnum 15x3.5 wrapped with Mickey Thompson 26x6R15 Sportsman radial rubber grace the front, and 15x9.25-inch wheels sporting Mickey Thompson 275/60-15 ET Street Street Radial Pro’s on the rear used on both the street and track. Stopping power is provided by front Aerospace Components street brakes and rear Strange Race vented disc brakes.
The interior features stock LX cloth seats but the back seats have been narrowed to clear the Wolfe mini tubs but still fold functionally. For safety, an 8.50 certified Wolfe 10-point Chromoly cage is tig welded inside. Other safety equipment includes a Simpson 5-point harness with quick release and Stroud window net. The interior also features a Scott Rod Fabrication center console that Jean modified to fit around the Kildruff Machine shifter. He also installed custom-made billet LED laser etched buttons for the engine fan, transmission fan, water pump, converter lockup, line lock and transbrake that were made in Australia. Let’s not forget the two cup holders in the center console, well, because street car. A Wolfe parachute mount with a Simpson parachute really help to halt things with a quickness.
“The main intention of this car is to remain a streetable 8-second car. The car has good street manners considering how extensive the modifications are,” Jean tells us. “Not many cars at this level anywhere can you reach in and turn the key to start it and it stays running. Chris Terry of CTR Race Cars has done an amazing job keeping the street manners in check without any surging or bucking.
A big thanks goes to Jean’s wife Emile, and his twins Hailey and Hunter, Chris Terry for all the tuning and suspension details, Heath Terry of Southside Resto and Rods for paint and body details, Pet Herron of Pro-Tech for chassis work, Scott Rod Fab, Jason Meador of Fastang Custom Fab, Dale Meers of Dale Meers Racing Engines, UPR, and Wolfe Racecraft. Another Thanks goes out to Alton Clements and Brian Mitchell.
The new setup has yet to be tested. “We are expecting four-digit power numbers and running at our 8.50 certification won’t be a problem.”
