While we generally spend most of our time at SEMA walking through the halls of the convention center, there's some pretty impressive cars outside, as well. Take this wild 1944 Mack fire truck, for example.

Built by Tom Stark of Precision Designs, the truck has been fitted with a 2005 Viper SRT10 V10 engine mated to a Dodge 48RE automatic transmission. The stock Mack axle remains up front, but the rear suspension and axle from a 2008 Ram truck resides out back. Other features include Dodge Ram SRT10 brakes, 24-inch American Force wheels and custom leather seating.

Lest you think this is just a show truck, Stark tells us that the owner plans to actually drive the thing. He is even going to make the trek from his home in Kansas City to the Goodguys Nationals in Columbus, Ohio come July.
