A strong can-do attitude coupled with a penchant for performance led Shane Isaacs down a road that ultimate formed not only his future, but also his marriage. Together with his wife, Teri, the couple fields a cool set of matching 1993 Ford Mustang Cobras in NMRA competition. 
 
Growing up, no one in Shane’s family was involved in racing to help shape his interest. He set out on his own, however, a case of sticker shock while he was in high school prompted him to take initiative. 
 
“I had a 1977 Ford C-10. but blew the motor in it. So, I bought a replacement from a racecar, pulled the old engine, and realized I was in over my head when I couldn’t get the new one in,” confessed the man of how he had failed to properly organize the parts and pieces during the extraction. “I took it to a shop and they charged me $2,500 just to set the engine in, so I said, screw it, I’ll learn to do it myself.”
 

That same attitude and drive not only helped Shane learn more about wrenching and racing, but assisted with his successful career in the trucking industry. His company, Isaacs Trucking, strengthened over two decades to operate more than a dozen rigs in the central Ohio region. Now, the 46-year-old owner-operator is enjoying the fruits of his labor.
 
Shane spent many days and many nights testing at his home track, Kil-Kare Raceway in Ohio, over the years. A single father at the time, he split his spare time between working, taking care of his son, Mason, and racing as much as possible. In time, he progressed to going quicker and faster, but also started spending more.
 
In 2008, Shane married Teri, who had come from a racing family herself.
 
“My dad was Charles Frazier. He was most known for having the ’64 Plymouth ‘Nasty Rumor’ car,” Teri shared, proud of what her beloved father, who passed away in 2007, had accomplished. “He was a Mopar man and got me my first racecar: a naturally aspirated ’87 Dodge Charger… and then, I married a Ford guy and now I’m racing Mustangs with turbos!”
 
Together, their blended bunch included six children and Teri was always quick to support and trust Shane in his endeavors.
 
“I started my business with one pickup truck, and Teri always believed in me and allowed me to grow to where we are today. Everything I have is thanks to her support,” said Shane lovingly.
 

As the children grew and Isaacs Trucking became a more streamlined operation, the couple found themselves with more free time and a few more dollars in the bank, and decided to get back to what they loved—drag racing.
 
“I really appreciate that Shane goes above and beyond and was able to get me back in a car after my father died. He had always been there on the starting line in my peripheral vision, so not having him anymore was devastating,” Teri noted of how her husband inspired her to get back in the driver’s seat in her father’s honor.
 
“My first class racing car was a Street Outlaw car, I really came out swinging,” he recalled of the Fox Mustang he had purchased as a roller in 2014. “I had a ProCharged SN-95 at the time that had blown a head gasket, so I robbed that block and heads and had BES Racing Engines build a motor to run as a turbocharged combination.”
 
Thanks to an introduction from its former owner, Shane met Chad Epperson of London Chassis Dyno and the two formed a friendship that quicky solidified. Thanks to help from Chad and, together with Teri, Shane campaigned the Street Outlaw car, which had an intricate flame-filled paint job featuring a longhorn front and center and was nicknamed the “Raging Bull,” as much as possible over the years.
 
“We started out with an air mattress in a trailer, but it was our time together and going out to eat with friends after a long day of racing was what we loved the most,” he reminisced.
 

At one point, Shane had owned a 1993 Ford Mustang Cobra with a mod motor which he ran in Limited Street. He sold it, but quickly regretted the decision. His friend, Jason Wagoner, also ran in NMRA and had a gorgeous, red 1993 Cobra that had caught Shane’s eye over the years.
 
“Jason had the car for, like, 20 years. London Chassis Dyno built it for him originally, but it had sat recently so I bugged him for three years about buying it,” joked Shane of how he finally got his friend to hand over the title and keys to the Cobra in 2021. “I brought it to London and we changed the converter to loosen it up, then debuted the car at Norwalk.”
 
Racing in the Mickey Thompson Street Car Challenge at the Inaugural NMRA Ford Performance Nationals at Summit Motorsports Park in Norwalk, Ohio, in June of 2021, Shane knew he had to keep his new-to-him street-legal Cobra under the 8.50-second mark to still be legal with his Chromoly roll cage. In qualifying, he ran 8.578 at 155.35 mph to settle into third. Meanwhile, Randy Thomas went 8.393 at 164.49 mph with his 2010 Mustang and was only allowed to continue as long as he didn’t run too quickly in eliminations.
 
Both Shane and Thomas kept their cars in check throughout eliminations and met up with each other in the final round.
 
“I had been planning to slow it down, but my transbrake button stuck and my adrenaline was pumping and… when I caught him [Randy Thomas] the racer in me took over and I couldn’t let him get to the finish first,” laughed Shane, who still lifted at the 1,000-foot mark and even jammed on the brakes, but still wound up running considerably under the safe-zone with his impressive 8.089 at 172.14mph pass.
 

Thomas, too, ran quicker than allowed with his 8.432 at 163.26mph blast. As a result, both men were disqualified and an incredibly unusual double-DQ final round resulted. In the winner’s circle, the unprecedented circumstances resulted in the trophy being cut in half so that each of the co-runners up would receive their portion as a memento to mark the occasion in a show of good sportsmanship.
 
Shane’s Cobra got a lot of attention that weekend, for more than just its jaw-dropping performance. The absolutely immaculate, mint condition Mustang features a full interior complete with original leather, dashboard, and more.
 
“It’s absolutely pristine and definitely still a street car,” said the proud owner. “It isn’t mini-tubbed, either. The only part that’s been changed externally is the cowl-induction hood. Otherwise, it hasn’t been cut up at all.”
 
Under the hood, though, it’s a different story. The 347 cubic-inch, Dart block-based small-block Ford powerplant from Tony Bischoff at BES waits for the commands from the Holley Dominator EFI system, tuned by Jeff Wightman, to unleash its fury. With twin 76mm Forced Inductions turbochargers at the ready, too, the machine produces more than 1,800-horsepower to its rear wheels and is capable of producing low 7-second quarter-mile elapsed times. 
 

Backing the bullet is a simple yet capable two-speed Powerglide transmission from Rossler and a bolt-together TCI torque converter. 
 
Still running on a stock-style suspension setup, Shane’s Cobra is mildly upgraded with Eibach springs and Strange Engineering drag shocks in the back and coilovers in the front. Similarly, the Ford 8.8-inch rearend contains a spool and 4.10 gears.
 
Not long after the comical conclusion to the Norwalk event, Shane had the opportunity to pick up yet another pristine 1993 Ford Mustang Cobra. This one, which was swathed in the coveted teal color, had originally belonged to Jeff Wightman who had purchased it new from the factory floor.
 
“Jeff [Wightman] let go of the car and then I heard it went somewhere doing no-time racing, then Lukas Weldon posted it for sale,” Shane shared of how he had the opportunity to obtain the car he had always admired. “I’m having a new car build, but I knew it was a long way from being done, and this was a 25.3 SFI cert, so I went ahead and got it.”
 
Somewhere in between owners, though, the engine received a “Band-Aid” repair with mismatched pistons. Shane, sadly, didn’t discover that fact until it was too late.
 

With both of the Fox SVT Cobras in attendance for the 23rd Annual Whipple Superchargers NMRA World Finals Presented by Competition Clutch featuring the Holley Intergalactic Ford Festival at Kentucky’s Beech Bend Raceway Park in early October, 2021, Shane and Teri each would have the chance to compete.
 
Running in True Street with the red entry, Teri clicked off passes of 8.781 seconds and 9.327-seconds to average 9.054 seconds overall. The couple had dialed back the 7-second-capable ride to allow her to get some seat time before turning the wick up, and Teri had a blast tearing it up on the track. 
 
“The car got hot and I got a little rattled, so that’s why I ran the slower time. But it was my first time running it in True Street, so there was definitely a learning curve,” she said candidly. Still, Teri did a terrific job in a huge field of cars and impressively took home the 9-second category runner up honors for her efforts, as Matthew Ballard’s perfect 9.000-second average proved impossible to beat.
 
Meanwhile, Shane was eager to put the first few laps on his new teal toy in the Mickey Thompson Street Car Challenge heads-up eliminator category. Also equipped with a Holley Dominator EFI, Wightman was remote tuning for Shane for the weekend—ironically on the same car which he owned many years ago—as the Fox switched from its former fuel to VP Racing Fuels’ Q16 for the weekend.
 

Qualifying produced pleasant results, and his best run of 8.285 at 163.83 mph placed him third on the list. Ready for eliminations, Shane pulled the Cobra into the water box to begin his burnout and get rolling.
 
“And, it blew the head gasket right there,” lamented the driver who knew his car was capable of so much more. “I know it would have been me and Donato Sierchio in the finals…”
 
Back home, Shane tore into the engine and discovered the hodgepodge of pistons that proved problematic. He turned to his trusted engine builder, Tony Bischoff of BES, to help rectify the situation and Bischoff built a new 347ci small-block Ford for Shane.
 
“I’ve only met Tony once, but he’s got a great relationship with Chad [Epperson], my builder, and I have seen the high-end engines he builds take relentless abuse. So, I trust him. Tony always takes care of us and gets what we need done as quickly as possible,” asserted Shane, who has enjoyed a long relationship with both shops.
 
Next, the engine was paired with a two-speed Powerglide from Rossler, the same as in Shane’s red Cobra.
 
“Rossler builds amazing transmissions and has great customer service,” he added of why he chooses to use the particular builder.
 
A longtime turbo fan, Shane once again opted for turbocharged boost as his preferred forced induction. This time, a single 76mm unit from Midwest Turbo was selected to comply with NMRA VP Racing Madditives Renegade class rules.
 
“It was a bit of a learning curve going from the ProCharger early on to the turbo and bumping in and spooling it, but I am always looking for something new to learn and I like a challenged,” explained Shane of his choice. “When that baby’s spooled up, the top end power from a turbo is really unbeatable. You see the other guy ahead and it’s fun to reel ‘em in.”
 
Other than a stout engine combination, Shane kept the teal Cobra fairly simple with its suspension. Swaying slightly more toward street than strip, though, he opted for AFCO by Menscer Motorsports four-way adjustable shocks in the rear with two-way adjustables in the front and a braced 8.8-inch rearend.
 

With their 2022 season looming, both Shane and Teri are antsy to get back to racing. Teri will be running the red Cobra in TorqStorm Superchargers True Street competition, while Shane will most likely turn up in VP Racing Madditives Renegade with the teal one.
 
“Our first race will likely be Rockingham,” he confirmed of the couple’s plans to attend the 14th Annual Scoggin-Dickey Parts Center NMRA/NMCA All-Star Nationals Presented by MAHLE Motorsport in North Carolina in late April.
 
Shane’s new car, a 2005 Mustang, is still in the process of being built but will be a formidable 25.2 SFI certified contender when it’s completed. Another BES-built engine, of course, will be under its hood with 440 cubic inches of turbocharged displacement. Intended to be run at the X275 level, Shane is considering bolting on a smaller turbo and using that as his Renegade entry instead, but most likely won’t be sure until mid-season.
 
While racing is certainly at the forefront of both Shane and Teri’s minds, one of Shane’s primary goals is to get the teal Cobra back to its former glory.
 
“I want the car to be like it was when Jeff [Wightman] first had it, and then I want to sell it back to him once he’s ready,” said Shane of his friend. Shane still has his old SN-95, too, which donated its engine to his Raging Bull ride. “I just Coyote-swapped that one. It’s got an 8-point cage—I bought it new and have had it too long to cut it up—and I’ll use it as a street car to cruise in.”
 
Regardless of where he winds up or what class he runs, Shane is happy to be doing it alongside his son, Mason, now 24, who helps out as a mechanic, and Teri is happy to be running in her father’s honor.
 
“It’s great doing this as a family. We encourage each other, yell at each other… whatever,” he said jovially of the competitive streak which both parties possess. No matter what transpires in the pits, though, each spouse makes sure to always be there to support the other. “There’s simply nothing better than having this time with them.”
