A cammed 5.3-liter and reportedly heavy-duty-rebuilt four-speed give this LS a distinctly modified drivetrain, with the Envoy-sourced cabin adding to its one-off configuration. At 208,000 miles, it sits well above the 3,500-to-146,300-mile range of other observed examples of this generation. The body was refinished after the seller bought it, and the camshaft, valvetrain, and lowered suspension are all modifications.
