Check the license plate, and the carefully tucked exhaust, right between the right bumper and the rear tire, nice A welders car I think, and I can't tell if it's the clutch or brake pedal, but, "Ho down" is imaginative!
If there were bonus points for rare applications never seen before, this guy would beat all the competition. I think this long ram carb setup is from a Max Wedge 413, the only thing I've seen of this design. But putting it on a rod, and letting it all hang out? Now that's cool, unlike the factory's keeping stuff out of sight under a hood where I never get to see the cool stuff.
