Artists pull inspiration from everywhere. They can be walking down the street and see an odd shapped spoon on the ground; something that someone had run over and the next thing you know they are creating an amazing work of art. All because a bent spoon inspired them.

Well, for Randy Grubb, his inspiration came in the form of a 12V71 Detroit Diesel. The engine is an 852 cubic inch 2 stroke diesel engine that produces 474 horsepower and 1,200 lb-ft of torque. The 12 cylinders receive air via the two factory 6-71 blowers that are mounted inline.

With the engine in hand, Grubb did what he does best. He created a work of art around this engine. If you don’t know Grubb, he was the one that designed and originally built Jay Leno’s Tank Car. “I view myself as an automotive artist creating full size sculptures that you get to drive,” says Grubb. He has built a number of vehicles from the ground up and they are all “over the top” in one form or another.

Anyways, back to the “Piss’d Off Pete. Once Grubb secured the engine, he took a 1960 Peterbilt 351 and went to work. He cut 5 inches out of the back, 8 out of the front to give it a slight rake look. The front windshield was formed to follow the lines of the cowl. So, from the front, it looks like it’s angry.

Behind the 12V71 is a Allison 740D 4 speed automatic which sends power to a Rockwell rear end with 2.70 gears. The wheels are custom made 12 spoke wheels up front with one off Baer Brakes. Everywhere you look it is an amazing machine.
