Randy Grubb's tricked out Peterbilt features a 12v71 Detroit Diesel with two 671 superchargers
This cool ride started out life as a 1965 Peterbilt Model 351 cab, which creator Randy Grubb kept seeing parked in an old logger's place near his home in rural Oregon. After years of driving by it, he finally decided to stop for a closer look in late 2008.
The hot rod hauler puts out 500 horsepower and 1000 lb-ft of torque at the redline of just 2,800 rpm. Rocking an engine designed to pull 150,000-lb loads, while weighing in at a mere 8,500 lbs, Grubb says the vehicle “could cruise down the freeway at 70 miles an hour at only 1,500 rpm.” There's no way it can pass emission tests, though, so it's future is solely as a display piece and an occasional ride down less-populated roads.
