In the days when gas was really cheap, back before high-performance SUVs dotted the shopping mall landscape, if you wanted a very fast SUV, you had few options. Sure, you could still get a big block in your Suburban, but that engine only offered 230 wheezing horses.

But companies like Lingenfelter were doing God's work and giving the Suburban what it really needed. More inches and more power.

Six hundred and five. In modern parlance, nine point nine. That's cubic inches and liters. That's like two 5.0L V8s. The displacement comes from a bored-out engine originally intended for a boat.

That means more than 550 hp and 705 lb-ft of torque. In a truck that tips the scales well over 6,000 lbs. It's fitted into a 2500 Suburban chassis to make sure the rest of the driveline can handle propelling your house to 60 mph in under five seconds.

When they built the original prototype in 1994, Lingenfelter told Car and Driver that it didn't expect to actually build any of the monster 'Burbs.

But they did build some. And you can buy one.

This one is for sale at Millennium Motors in Monroe, WA. It's a 1999 Chevrolet Suburban K2500 with that monster engine crammed underhood. Bring this one home and start scaring your local supercar owners. With you and seven friends on board.
