This is Syclone #512 of only 2995 built EVER.
These were only built in 1991 by a company called PAS in conjunction with GMC. Stock performance is 0-60 in 4.3 sec (4.6 in the rain!!!) and the 1/4 mile in 13.1 STOCK!!! Full time all wheel drive, a Garrett air to water intercooler, a 700r4 tranny, and a mitsubishi turbo'd chevy 4.3L are the muscle behind this beast. Stock they are rated at 280hp and 350tq , but were believed to be UNDERRATED as to not outdue the FLAGSHIP Corvette ( rated at 285 that year )....and I have seen dynos for these setups STOCK running 330hp and 400lbs torque to the WHEELS!!! They weigh in at 3500lbs :) ---
The interior is like stepping into a time warp to 1991....it is PERFECT. Not one flaw. I want to repaint it soon, so the cladding matches the paint. I bought him with 63,500 miles....what a beauty. He now has 69,000 miles. ---
Here he is stock when I bought him a few weeks back:
