Production of Shelby GT350 is coming to an end

One Autoblog staffer who drove the limited-edition Shelby GT350 wrote it probably was the best Mustang he'd driven, but, at some point, the fun had to come to an end: December 31 is the last day the GT350 will be available to order.
The GT350's option list has evolved much like it did for the original 1965-67 GT350. For 2011, the 45th Anniversary edition only came in coupe form and was painted white with blue stripes, just as with the 1965 car. The 2012 GT350 was offered as a coupe or convertible, and three colors were added to the option list, just like the 1966 model. For 2013, more colors and options were added in addition to equipment and styling updates, which resulted in Wilwood instead of Baer brakes. No major changes were made for the 2014 model. From the first car in 2011, customers have been able to choose between three different configurations for their 5.0-liter V8: naturally aspirated with 440 horsepower, supercharged with 525 hp (with warranty) or supercharged with 624 hp (without warranty).
"When we unveiled this latest version of the Shelby GT350, we promised it would be built for a limited time to preserve its collectability and value," states John Luft, president of Shelby American. He may have a point, because the original GT350, which also had a limited production run, is among the most valuable muscle cars in the world.

Watch the Hennessey Ford GT makes its record run at Texas Mile

We said they'd probably be out with an official video, we did not lie. The Hennessey-powered camouflage Ford GT sat at one end of the runway at the Texas Mile sitting still. At the other end of the runway it had broken its own speed record, the twin-turbo 5.7-liter V8 pushing the aerodynamic supercar up to 267.6 miles per hour, a 4.3-mph improvement over the old mark.
There's not much in the video you haven't already seen, this just makes it official. That said, who doesn't want to see a twin-turbo Ford GT set an incredible speed record? You can watch it below.

Diesel Power finds the ultimate modified oil-burner

For nine years, Diesel Power magazine has run the Diesel Power Challenge, this year's grindfest being "a week-long torture test that features seven events, nine trucks, 8,000 horsepower, and nearly 15,000 pound-feet of torque." The road to being crowned "the most powerful truck" starts with a dyno run, and then continues through the completion of a CDL-style obstacle course, an eighth-of-a-mile drag race while towing a 10,000-pound trailer, a quarter-mile drag race without a trailer, a fuel economy test in the mountains and finally a sled-pulling test through a 300-foot-long packed-mud pit.
What kind of trucks get into such a fight? Last year's winner, for instance - who upgraded his truck this year to prove he didn't "luck into the win" - drives a 2008 Ford F-250 Super Duty with a 6.4-liter Power Stroke V8 upgraded with a custom intake, Elite Diesel triple turbos and a two-stage nitrous system. Another competitor has a 2005 Dodge Ram 2500 powered by a 5.9-liter Cummins inline-six, upgraded with Garrett turbos, dual-stage nitrous, a seven-inch exhaust stack and twin fans built into the bed to cool the Sun Coast Omega transmission. The numbers on that truck: 1,255 horsepower, and 2,063 pound-feet of torque at the wheels. Naturally, as the image above might suggest, things don't always end well.
You'll find all five videos covering this years challenge below. A scene in the dyno video sums it all up perfectly: a competitor leaves his nitrous on too long and the crew is treated to some ominous poppings, he leans out the window, throws both hands up and shouts, "Amer'ca!"
