Is that the 5.0 & SF readers never fail to disappoint at our annual competition
2007 Shelby GT500
As an interested spectator last year, David Shea was ready to step in and compete if we had anyone drop out at the last minute. Seeing David's GT500 in person made us realize his car was ideal for the KOTS, and we made sure to save him a spot this year.
David's GT500 is the first Mustang he's ever owned, and the first car he's owned making over 300 hp at the wheels. Of course, he realized that goal the day he bought his GT500. After learning about the re-launch of the GT500, David knew right then he was going to be all over it. However, with the mark-ups when the cars first came out, they were a little out of his price range.
After waiting for the right price, David made the move. "I drove the car home that night," David says. He considered himself lucky to own such a car and vowed to keep it stock. Of course, that didn't last long; after 350 miles and some nasty wheelhop, the mods started in earnest and didn't stop until he was satisfied.
David is proud to say that he performed 98 percent of its mods himself. Even the stuff other people did, he went back over what had been done to make sure it was to his level. There's basically nothing David hasn't touched on his Shelby, from the custom parts he made, to the countless hours of polishing he performed on all the aluminum. David's Shelby wears no chrome. He hand-polished all the bright work on the car to appear chrome. All that work paid off in the Engineering, and Fit and Finish categories.
His GT500 scored well in the real world thanks to swingout door bars, cold A/C, stock seatbelts, no warning lights or chimes, and the like. The only driving shortcoming was the car shutting off a couple times during our loop. Other than that, David's GT500 sounded like a NASCAR racer with its American Racing Headers/Bassani Xhaust combo.
David and I are of the same mind when it comes to shifter handles since his GT500 boasts a pistol-grip knob. That is my shift knob of choice, and David's GT500 makes you feel like a rock star when bangin' through the gears. David's GT500 handled great, braked well, and with a Kenne Bell 2.8-liter supercharger, reaching your happy place was just a throttle stab away. The throttle response was instant, but that's the nature of positive-displacement, twin-screw superchargers so that was of no surprise.
His car was a little cramped, but he's not tall enough to be an NBA water boy. I was just visiting--he's the car's primary inhabitant so he didn't lose any real points because of that. Had it not been for the stalling issue, David's car could've scored a perfect 10 in the Ride and Drive, but that was a big hit to an otherwise perfect ride.
Thanks to David's attention to detail and tireless polishing, his Shelby scored a 9.5 in Engineering and a 9 in Fit and Finish. Due to the unfortunate stalling issue, his Shelby scored an 8 in the Ride and Drive, and with a 10.572/135-mph pass, David's Shelby scored a 5 in the Drag Race category. In the Popular Vote category, it seemed David's work went sadly unnoticed with a 4 in that category. In the all-important Dyno category, his Shelby's 762 hp was only good for the middle of the KOTS road, scoring a 5.
