New Chevy Small Block crate engine has 405 hp, endless possibilities

With decades of history, the Chevrolet Small Block V8 has definitely stood the test of time, and the company has kept finding ways to make it better. At this year's SEMA Show in November, Chevy Performance is unveiling the latest upgrade to that legacy with the new ZZ6 350-cubic-inch (5.7-liter) crate engine. Offering 405 horsepower and 405 pound-feet of torque, the mill should add a big dose of power to any project car. For the ZZ6, Chevy is working to improve the Small Block's high-rpm performance. To make that happen, the engine has Fast Burn aluminum cylinder heads and an updated valvetrain inspired by the LS family of powerplants. Large intake runners help with the airflow, and the valve springs use a tapered design that allows for less reciprocating mass. The mill also packs a forged steel crankshaft and high-silicon aluminum pistons inside of a cast iron block. Chevy is offering the engine in two versions depending on what the builder needs. The Base configuration comes with an intake, distributor, water pump, and a few other parts but lacks carburetor and accessories. Conversely, the Turn Key option has everything, including the carb, air cleaner, starter, alternator, and more. More details about their availability will be announced at SEMA. NEW ZZ6 CHEVY SMALL BLOCK ADVANCES CRATE ENGINE LEGACY Revised Fast Burn heads with LS-inspired valvetrain enhance high-rpm performance 2015-10-02 DETROIT – Developed with contemporary technologies, including a high-rpm valvetrain, Chevrolet Performance's new ZZ6 crate engine offers builders a modern twist on the classic Chevy Small Block 350. It uses updated Fast Burn cylinder heads with beehive-style valve springs inspired by the LS engine family – a feature that enhances high-rpm capability, enabling the new high-performance engine to achieve 405 horsepower and 405 lb-ft of torque. That's more power than any factory produced 350 engine ever installed in a Chevrolet production vehicle and it's one of the most powerful 350 Small Block-based crate engines in the nearly 27-year history of the "ZZ" lineup. "The new ZZ6 is the ultimate ZZ 350-based crate engine from Chevrolet Performance," said Jim Campbell, GM U.S. vice president of Performance Vehicles and Motorsports.

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.

GM invests $175 million in Chevy Camaro factory

General Motors just keeps rolling out portions of its $5.4-billion plan for factory upgrades over the next three years. In the latest announcement, the automotive giant is putting $175 million into the Lansing Grand River Assembly Plant for improvements to build the 2016 Chevrolet Camaro. The investment brings new equipment to the plant to build the pony car. An upgrade is needed to support Camaro-specific colors like Summit White, Bright Yellow, and Red Hot, and the factory is also getting two robotic framers. A second shift of 500 workers is resuming in Lansing later this summer to produce the model, as well. So far, GM has announced allocations for $2.8 billion of the $5.4 billion in upgrades. The investments include $1.2 billion to improve pickup production, $439 million for a paint shop for the Corvette, and more new equipment at other plants too. Lansing Grand River Plant Tools Up for 2016 Camaro $175 million investment enables production of lighter, more powerful model 2015-05-28 LANSING, Mich. – A $175 million investment for new tooling and equipment for the sixth-generation Chevrolet Camaro, and the return of hundreds of workers to build America's best-selling performance car for the last five years, was announced today. The facility improvements include three new paint systems for Camaro-specific colors: Summit White, Bright Yellow, and Red Hot. The investment also includes installation of two robotic framers, which allow better dimensional control to provide a more precise drive experience. The Lansing Grand River Assembly Plant will resume a second shift of 500 jobs in late summer. The all-new Chevrolet Camaro was introduced on Detroit's Belle Isle on May 16. The current generation Camaro has been America's favorite performance car for five consecutive years, attracting both long-term Camaro fans and new buyers to Chevrolet. To improve on that success, the sixth-generation Camaro elevates every aspect of Camaro with a suite of new technologies, even higher levels of performance and fuel economy, and a leaner, more athletic design. "I may be the luckiest mayor in America today," said Lansing Mayor Virg Bernero. "Gearing up for full-scale production of the legendary Chevy Camaro is a new high point in the more than two decades of extraordinary partnership between the City of Lansing, General Motors and the UAW.
