6.2L-Powered 1991 GMC Syclone
United States • 27 Jul 2026
Vehicle Details
AI Listing Summary
This 1991 GMC Syclone has been heavily modified with a 6.2L V8 engine swap, upgraded suspension, and Wilwood brakes, and features a refreshed interior with Vintage Air and a Kenwood head unit. Despite a clean title and no reported accidents, a past registration in a FEMA flood disaster area warrants attention.
Condition
7
The vehicle has undergone significant modifications including an engine swap, upgraded suspension and brakes, and interior and exterior cosmetic enhancements. While the listing states a clean title and no accidents, a FEMA flood disaster area registration note from 2005 raises a concern. The odometer shows 1,600 miles, but total mileage is unknown. These factors suggest it's in Very Good condition, requiring some consideration for its history and modifications.

This 1991 GMC Syclone is one of 2,995 examples produced for the model year, and it was modified circa 2016 with the installation of an LS-based 6.2-liter V8 that is backed by a three-speed automatic transmission with a reverse manual valve body.
The truck rides on 17″ ZR1-style wheels and has black-finished Wilwood calipers, AFCO Racing dampers, CalTracs traction bars, and a dual exhaust system with long-tube headers and MagnaFlow mufflers.
A repaint in black was also performed under prior ownership, and the cab has been equipped with a Vintage Air climate control system, a Kenwood head unit, an aftermarket shifter, and AutoMeter instrumentation.
