History

In 2001, the Blastolene Special was built by craftsman Randy Grubb. It is powered by a Continental AV1790-5B, [2] a huge engine that weighs as much as a Volkswagen Beetle, which was previously used in the 51-ton M47 Patton Tank in the 1950s. It also features a Greyhound bus transmission and a retro designed sheet metal body. Jay Leno put it into the extensive collection of cars he owns —84 cars and 73 motorcycles as of April 2006. [4] The car was built at Grubb's shop in Grants Pass, Oregon.

After purchasing the car, Jay Leno made numerous enhancements to the roadworthiness of the vehicle, including a new six-speed Allison automatic gearbox, new rear brakes, new electrical system, and chassis work. [3] The engine was later upgraded with fuel injection and twin turbochargers from Gale Banks Engineering. It now reportedly produces 1,600 hp (1,200 kW) and 3,000 lbf⋅ft (4,100 N⋅m) of torque. [5]
