Super Truck: 1991 GMC Syclone

This 1991 GMC Syclone is a project of sorts, seemingly a decent driver with a freshly rebuilt engine under the hood but also in need of the intercooler setup being installed before you can truly enjoy the performance these super trucks are capable of. The paint is certainly beading nicely based on the picture here of it parked outside in the rain (really?), and the Syclone wears a more modern set of aftermarket wheels than it originally came with. The hood sports an aftermarket “power bulge” of sorts, but hopefully, that’s the only cheap enhancement done to this limited production Syclone. Find it here on eBay with bidding to $9,100 and no reserve.

The Syclone wears a tonneau cover, so there’s more than a few alterations from stock that we can see in the photos. Fortunately, none of it is end-of-the-world stuff aside from the general offensiveness of aftermarket hood bulges. The wheels look sharp, but I can’t help feeling like the original rollers would look better. The Syclone is in an odd spot in the collector market, as you can snag a project-grade example for reasonable money, and it seems like their values haven’t changed that much over the last few years. Good ones still climb into the low 20s; average ones into the low teens.

The interior looks good, showing the stock buckets that were trimmed with a unique upholstery scheme for the Syclone and its Jimmy-bodied sibling, the Typhoon. The solitary photo of the cabin reveals no unsightly tears in the fabric or attempts to apply one’s own vision for custom colors. The Syclones were all automatics from the factory, and could apparently withstand a fair amount of engine tuning given how many modified examples of this boosted truck are running around at any given point in time. There’s no mention of any engine modifications on this example, but given the visual tweaks we see here, it’s a question worth asking.

The engine rebuild is definitely one part of the truck’s history that would be worth following up on. 160,000 miles is high, but it’s not necessarily a given that a maintained vehicle would need a rebuild at that point. Even as a performance truck, I feel like enough of these high-performance GMCs have survived with regular maintenance in stock condition. The seller notes that he’s still driving the Syclone, but without the intercooler setup installed, which seems like a minor punchlist item when it’s following a total engine overhaul. So, some questions remain, but the tidy cosmetics and presumed papertrail of receipts for the rebuild work should help quiet some lingering doubts.
