The first-generation Chevy Tahoe is an ideal example when it comes to a perfectly average vehicle. It's a good car, but nothing to write home about. Yet again, it's never had an LS9 crate engine before.

One Washington resident has fitted a 1998 Chevy Tahoe with an LS9 engine and sent off to the market. Normally, such an engine is reserved for a C6 Corvette ZR1. With an asking price of $21,000, this might be the best deal you'll ever find, considering the engine alone is worth that much when purchased from GM Performance Parts directly.

The swap was prepared by a fabrication shop in Washington, who tuned the truck once it was complete. The engine alone pushes 638 horsepower and 604 pound-feet of torque, but we don't have the actual specs for this super-Tahoe at this time. It kept its four-speed automatic gearbox, but the rear axle gearing has been modified to 3.73 for additional power.

It was already a model citizen SUV before the transformation, now it's become the king of the commute.
