GM applies for LT5, LTX trademarks... are new small block variants coming?

Recently discovered General Motors trademark applications for LT4, LT5, LT88 and LTX have observers wondering what kind of high-performance offerings could be on their way. A new LT4 would mark a return of the engine designation first used on the Corvette Grand Sport, SLP Pontiac Firehawk and SLP Chevrolet Camaro SS from 1996 and 1997. Supposition at Corvette Forum - which provided advance intel on the C7 like these leaked images - believes a new LT4 could go into the high-performance trim of the next-gen, 2015 Camaro that would be more powerful than the 580-horsepower Camaro ZL1.
Seeing an LT5 again would also be déjà vu - in its former life it was a 5.7-liter V8 for the C4 Corvette ZR-1 from 1990-1994 designed by Lotus, producing from 370 hp to 405 hp. A mix of rumor and hope is that the new LT5 will be a supercharged evolution of the 6.2-liter LT1 (pictured) placed in the new C7 Corvette, and that it will go into the C7 version of the ZR1 pumping out something like 700 hp.
The LTX trademark is, as with that last letter, a complete mystery. If the "X" isn't a generic way to denote the whole LT family, it's wondered if it LTX could refer to a crate motor offering like the LSX.

Final C6 Corvette built in Bowling Green

With all of the attention given to the 2014 Chevrolet Corvette Stingray lately, you could be forgiven for thinking that it's already well along in production, yet tooling up for the new C7 has only just begun. In fact, production of the outgoing C6 generation in Bowling Green, Kentucky just halted on Thursday.
As the C6 has aged, production numbers have predictably ebbed along with demand, but this year, the addition of the 427 and 60th anniversary models resulted in an uptick in vehicles built - this, despite a model year shortened by around 25 percent to accomodate the new model changeover. The final C6 Corvette ever, No. 13,466 built this year, was a white 427 Convertible destined for the General Motors Heritage Center museum. The car's 7.0-liter V8 heart was assembled by Corvette chief engineer Tadge Juechter himself.
In total, Bowling Green pushed out 215,100 C6 Corvettes over nine years. If you're still a C6 fan at heart and are hoping to get a good deal on a phase-out model, step lively - Chevrolet reportedly had about 6,100 unsold units, which Autoweek suggests is good for around five and a half months of supply at the model's current sales rates. Given that demand will likely slacken even further as the C7 draws closer, that should be a big enough stockpile to keep dealers satisfied until 2014 Stingrays begin showing up on their forecourts in December.

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.
