The Syclone is a veritable street eater. She's based on the GMC S15 Sonoma. GMC added special ground effects, wheels, and decals to enhance the truck's image. Under it's pretty exterior is a mustang-eating 4.3 liter Vortec V-6. What's so damn special you're asking? Well, it could be the all wheel drive system that was mated to the TH 700R4 automatic transmission. Or it could be the liquid intercooled turbo that pushes up to 280hp (disputed to be 330hp) and torque up to 360 lb-ft. Only 2995 of these puppies were made in 1991 (3 in 1992). From a stop, 60mph hits you in under 5 seconds, the quarter mile passes under 14.
