There are a few things that might tip-off someone to the potential in this 1981 Caprice, one being the cutout in the hood and the other being the beefier tires. Other than that, this car easily falls under the sleeper category. Power comes from a 4.8L iron block LQx V8 connected to a Garrett 70mm turbocharger. The owner put a lot of time and effort into this super sleeper and I doubt there is another out there as nice.
