900hp LSX-Powered 2015 Camaro Z/28 Heads To Bring A Trailer

With seven liters of glorious, naturally aspirated LS7, massive carbon-ceramic brakes, and sophisticated Multimatic DSSV spool-valve dampers, the fifth-generation Camaro Z/28 has earned a reputation as one of the greatest track-focused Chevrolets ever built. But every now and then, some random enthusiast comes along and asks the question: What happens if you keep everything that makes a Z/28 special and add nearly twice the horsepower? That’s exactly the question this awesome Camaro answers.

Currently listed on Bring a Trailer, this black-on-black Z/28 is one of just 1,292 examples produced for the 2015 model year. While the car’s exterior still wears all the aggressive factory styling that made the Z/28 famous, there’s been a massive transformation under its hood. Instead of sticking with the familiar 427 we all know and love, this Chevy’s current owner installed 427 cubic inches of Late Model Engines LSX topped by a 2.9-liter Whipple supercharger.

Not surprisingly, that engine features the kind of spec sheet that reads like an enthusiast’s wish list. A forged Callies Compstar crank, forged Callies Compstar rods, and a custom Late Model Throttle cam work well with Diamond pistons. Head work includes dual valve springs, hardened pushrods, and Johnson slow leakdown lifters. Fuel is supplied by FIC 127-pound injectors, an auxiliary fuel pump, AN plumbing, and a DSX flex-fuel sensor. And even the details are on point, with ARP fasteners complementing Clevite bearings.

While 505 horsepower from the factory was nice, rest assured that this setup takes things to a whole new level. On a steady stream of E85, the supercharged LME mill laid down an impressive 904 horsepower and 783 lb./ft. of torque on the chassis dyno.

Naturally, that kind of power required upgrades throughout the driveline. TREMEC’s tough TR-6060 six-speed manual remains in place, but now utilizes a Monster LT1-spec triple-disc clutch, which is stacked with a billet flywheel, an upgraded release bearing support, and a Hurst shifter. Power travels through an aluminum, 3.5-inch Driveshaft Shop driveshaft before reaching the factory helical limited-slip differential, complete with its external cooler. Kooks 1-7/8-inch headers feed a MagnaFlow X-pipe exhaust that’s completely devoid of catalytic converters.

Perhaps the most impressive aspect of this build is that the buyer is still getting everything that made the Z/28 such a great track car. The Z/28’s legendary spool-valve suspension, Performance Traction Management, forged wheels, and Brembo carbon-ceramic brake package all remain intact. Inside, Recaro seats, suede accents, and the factory Z/28 interior continue to remind you that this high-horsepower monster isn’t just some cobbled-together straight-line beater.

The fifth-generation Camaro Z/28 has always been a driver’s car, engineered to dominate road courses rather than win dyno competitions. It’s no small feat that this build manages to preserve everything that made the original so special while adding nearly 400 horsepower to the equation. With bidding still well below what it would cost to recreate a build of this caliber, this LSX-powered Z/28 may end up being one of the biggest performance bargains to cross the auction block this year.
