First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.

2013 Chevy COPO Camaro announced with two new engines and manual option

Chevrolet is following up the 2012 COPO Camaro with another limited run of the drag-strip-ready production car for 2013. Ditching the superchargers, the 2013 COPO Camaro can only be equipped with one of three naturally aspirated V8 engines, and other new features include the option of a manual transmission, new front springs, some minor styling changes and a lower starting price of $86,000. All cars are designed to abide by the rules of the NHRA's Stock Eliminator or Super Stock classifications, depending on in which series buyers wish to enter their Chevrolet Camaro.
Returning for 2013 is the 427-cubic-inch V8 producing 425 horsepower, but the new engines include a 325-hp 350-CID V8 and a 375-hp 396-CID V8. Buyers can select to purchase all three engines, and each will be matched with the sequence number of that car; the track-only COPO cars will not have vehicle identification numbers and can't be registered for street use.
Chevrolet is also offering unique enthusiast-specific options such as a COPO Build Book and the opportunity for owners to help assemble their car's engine at the Chevrolet Performance Build Center in Wixom, MI.

AMC Trans Am Javelin SST, an ultra-rare underdog, is up for auction

Among the rarest of the American muscle cars that went racing in the early Seventies — cars including the Camaro Z/28 and the Boss 302 Mustang — the 1970 AMC Trans Am Javelin SST may be the most hard to find, and among the most valuable. Only 100 units of this unique Javelin were produced, and one of them is up for auction at the Mecum event in Dallas on September 20. The Trans Am Javelin was fashioned in a patriotic livery of tricolor paint — red, white and blue — and arrived after the American Motors Corporation had decided in 1968 to compete in the Trans Am racing series against Ford and General Motors. The company's chief driver, Mark Donohue, would dominate the 1971 season, taking seven wins in his Javelin AMX and that yearÂ’s SCCA Trans-Am Championship. AMC took the trophy with 82 points, well ahead of Ford's 61, Chevrolet's 17 and Pontiac's paltry 7. The example listed for auction came equipped with a 390-cubic-inch V-8 engine with 325 horsepower at 5,000 rpm and 420 pound-feet of torque, power steering and brakes, dual exhaust, BorgWarner four-speed manual transmission and Hurst competition shifter. Its “ram induction system” sealed a chamber around the air filter so that cool air from the functional hood scoop would be funneled into the intake. This JavÂ’s factory price was $3,995 — a mere $32,000 or so in today's money, though it was expensive by the standards of the time. The 100 Trans Ams were among 19,714 Javelin units built in 1970, so they started out rare, and today the surviving examples are highly collectible, if and when they come up for sale.
