Muscle Truck: 1991 GMC Syclone

This 1991 GMC Syclone pickup is presented as a late-production example that is described as nice, clean, and original. Late production in this case means number 2,336 off the line of a total production of 2,995 Syclones made in 1991, although I’m not sure how much value it adds in such a limited run. In any case, this example is said to have cold A/C and none of the broken body cladding we typically see on tired examples. Find it here on eBay with bidding over $15K.

There’s no reserve on this auction, so someone will be going home with one of the most powerful performance trucks of its day. The Syclone hails from a unique era when domestic manufacturers were hell-bent on building high-performance versions of their most powerful trucks, which included the Ford F150 Lightning; Chevy SS; and the Syclone and its Jimmy-based sibling, the Typhoon.

This Syclone is said to have a well-kept interior and that it was always stored indoors. The interiors were nothing exotic, but they could look tired like any other truck when not paid attention to. This one looks to be holding up well, and with just 58,768 miles on the clock, there’s no reason it shouldn’t be in good condition. The lack of any sun damage would seem to back up the seller’s claims of indoor storage.

The Syclone’s performance is still incredibly respectable today, a testament to how far GM’s engineers pushed the envelop when they introduced this turbocharged beast. The Syclone could haul ass to 60 in just 4.3 seconds and eclipse the quarter mile in under 14. That still qualifies for bananas performance in the pickup truck category, and this Syclone looks to be in the sort of condition that likely means the truck hasn’t lost a step.

    I swear I think the fake “Cowl Induction” hood has finally become the automotive equivalent of a fine rat tail hair do.

    Forgive me for possibly being a little dense but what is the significance of it being a late production example? The time spent dreaming up that ad campaign should have been spent on taking better photos IMO.

    Pretty Sharp and I dig the hood too although stock is best on these for value. I bought my Typhoon new In 92 and set about making it faster.

    Thought it was super badass until Neigbor let me drive his stock Syclone. Dang that thing was quick!

    Had a chance to buy one with its engine out locally earlier this year for a fair price but don’t have time or space for another project. And they are really small inside. Kinda felt like I was wearing it.

    Still love to have one someday

    How many pounds of ballast are required to keep this going straight under full throttle? Another GM(C) answer to a question nobody asked. The Typhoon almost makes sense compared to this.

      It’s all wheel drive so that is of no concern.

      I seem to recall the load limit for stuff in the pickup bed for this vehicle was 500 lbs.

    Bought my wife one for our 25th wedding anniversary in 1991 truck was amazing handling was great almost equal to a Vette of the era. Rode very well considering the short wheelbase. We sold it after four years due to the fact her German Shepherd was not happy with the small front seat. It was a great ride.

      That’s why I bought my wife a Yorkie!

    Never made a club cab or extended cab of these as far as I know. My 91 would knock my head against the rear cab window were it not for the high back bucket seats. Very comfortable but cramped.

    I owned one of these and at 6’0″ 220 lbs I concur that it feels like wearing it. I can also confirm it they do some pretty great burnouts with the front prop shaft removed!
    Not that it matters because this has already sold but looks like aftermarket hood and wheels for sure. The battery looks like it was moved to the bed. Also the cladding was painted gloss black. They all came with a matte finish. Not sure late model matters they were only made one year. There were some “Saudi Syclones” that may have a more rare aspect to an already rare vehicle.
