Standard, a 1998 Chevrolet Tahoe came equipped with a 5.7-liter V8 offering up 250 hp and 330 lb-ft of torque. Those are respectable figures by any rational standard, but frankly, rational standards are boring. We're much more interested in , which ditched its 5.7-liter for the 6.2-liter supercharged V8 out of the old Corvette ZR1.
The one that makes 638 hp and 604 lb-ft.
Yes, some lunatic thought it was a good idea to put an LS9 in a late-'90s Tahoe. I'd like to meet this lunatic and buy them a beer.
Welcome to You Must Buy, our daily look at the cars you really should be buying instead of that boring commuter sedan.
This car on Bring a Trailer, and the R&T office is amazed. And it's not just some home-brew nightmare—this Tahoe looks looks to be properly built.
The work for this conversion was done by a Chevy dealer in Olympia, Washington, and the listing details some extent of what's been done:
A strengthened 1-ton 4-speed automatic transmission was added along with upgraded Baer brakes, Superlift lowering suspension, 35-spline Dana 60 rear end with Detroit Locker rear differential, upgraded cooling, custom traction bars, and much more.
This truck is amazingly clean, too, with an interior that looks like it just came off the showroom floor. I love the subtlety as well; most people won't notice the lowered suspension, the polished 20-inch GMC wheels, and drilled/slotted brake discs—they'll just see a surprisingly clean old-ish truck.
At the moment, the odometer reads 34,886 miles, with around 2000 added on this new drivetrain. The Tahoe is finished in Light Pewter metallic, seemingly the only color these trucks were offered in.
It's hard to put a value on something like this—the total cost of the engine swap and other upgrades isn't mentioned in the listing. But, we do know that a brand-new LS9 crate motor costs well over $20,000 from GM Performance Parts, and clearly, a lot more money went into this truck.
