The LX recipe was simple: 400 rwhp in a fast street car with amenities like A/C and heat. James knew Chris Carroll as a formidable racer and builder in the area. Boring and stroking a Ford Racing Boss 302 block, Chris built a naturally aspirated 347 with "good compression (10.6:1), a decent cam (custom grind), and good heads (AFR 205s)."

Chris calls this 347 "a proven combination that we've done several times" and one that "seems to be the one making the numbers." The build met James' horsepower expectations, as the dyno showed 404 to the rear wheels and 375 lb-ft of torque. Chris says this power makes the LX a solid 11-second quarter-mile car, say 11.40s, and low 10s on nitrous. "With the 150-shot, we made a hair over 520 and 542 on torque," he added.

The full specifications on the LX reveal a highly customized '93 model. Yet, the car still looks like a vintage LX. Meanwhile, the Shelby is virtually a stock ride except for "monstrous" power and the few suspension upgrades. "When they were putting the [turbocharger] kit on, I had them put on the BMR rear adjustable suspension components-the lower control arms and the Panhard bar," James said.

The Shelby gets its awesome power from the stock supercharged 5.4, compound-boosted by Hellion's twin 61mm turbos with intercooler and supporting mods. "I opted to keep the blower on," James said. "A lot of people argue to take the blower off, but with the turbos feeding into a supercharger, the car is a monster." Meanwhile, the whir and purr of the 5.4 at idle is misleading. "You drive that car and don't put your foot in it, it's just like driving a stock GT500," James elaborated.

Both cars are in a constant of upgrading. James calls them "ongoing goals." He just might get as much fun planning and dreaming of what the next mods might be as he does from lighting the firepower at his disposal today. He's already talking about a T76 Hellion turbo kit with a tubular K-member on the LX, and he's trying to decide whether or not to go to coilovers all around on the Shelby ...
