GarageScout Take

This 1991 GMC Syclone has been significantly altered from its original specification with a 6.2-liter LS V8 and a three-speed automatic transmission.

Strengths

  • Low mileage on replacement odometer at 1,600 miles
  • Comprehensive performance modifications including engine, suspension, and brakes
  • Includes modern comfort features such as Vintage Air climate control and a Kenwood head unit

Watch For

  • Original 4-cylinder drivetrain replaced with LS V8
  • Automatic transmission is a departure from the original 4-speed manual or 4L60 automatic
  • Significant modifications reduce factory originality
