This 1998 Chevrolet Tahoe is being auctioned on Bring a Trailer in Issaquah, Washington with a current bid of $21,000. The factory 5.7 L Vortec V8 was replaced by a supercharged 6.2 L LS9 V8 crate engine at Titus Will Chevrolet of Olympia, Washington in 2012-2013. That bumped the Tahoe’s power from 255 horsepower and 335 lb-ft of torque to 638 horsepower and 604 lb-ft of torque. The LS9 is equipped with the factory’s dry sump system, Spanky’s Rod Shop custom fuel injectors and wiring harness, and custom headers. The drivetrain consists of a beefy 4L80E four-speed automatic transmission, upgraded GM Performance front axle with Driveshaft Shop level 5 axles, Dana 60 rear axle with Detroit Locker diff and 3.73 gears. The Tahoe rides on a Superlift lowered suspension, custom sway and traction bars, Baer drilled and vented disc brakes with 14-inch rotors in front and 13-inch rotors in back.

I have huge respect for the guy who built it. LS9 crate motor costs at least 17k, you can buy a used Tahoe of this generation for 5-6k. So basically engine costs a lot more than the car itself. It shows that the owner really loved this car. And that’s awesome.
