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.

Weekly Recap: The implications of strong new car sales

New car sales are on a roll in the United States this year, and analysts are optimistic the industry will maintain its torrid pace. Sales increased 1.6 percent in May and reached an eye-popping seasonally-adjusted selling rate of 17.8 million, the strongest pace since July 2005, according TrueCar research. That positions the industry for one of its strongest years ever, as consumer confidence, low interest rates, low fuel costs, and an influx of new products propel gains. In addition to the positive economic factors, May also featured warmer weather across much of the US, an extra weekend, and it came on the heels of relatively weak April sales. Analysts suggest income tax refunds and the promise of summer driving and vacations also traditionally help May sales. "While 2015 will be one of the best years in the history of the US industry, in some ways it may be the very best ever," IHS Automotive analyst Tom Libby wrote in a commentary. "Not only are new vehicle registration volumes approaching the record levels of the early 2000s, but now registrations and production capacity are much more closely aligned so the industry is much more healthy." Capacity, an indicator of the auto sector's health, is also expected to grow. Morgan Stanley predicts it will eventually hit at least 20 million units per year, as many companies, including General Motors, Ford, Tesla, and Volvo are investing in new or upgraded factories. "The best predictor of US auto sales is the growth in capacity, and frankly, we're losing count of all of the additions – there's literally something new and big every week," Morgan Stanley said in a research note. Transaction prices, another telling indicator, also continue to show strength. They rose four percent in May to $32,452 per vehicle, and incentives dropped $10 per vehicle to $2,661, TrueCar said. "New vehicle sector and segment preference indicates consumers are confident about the economy and their finances," TrueCar president John Krafcik said in a statement. Still, Morgan Stanley noted the robust sales did little to immediately impact automaker stock prices and suggested it might be a prime time to sell if sales reach the 18-million pace. "Perhaps the biggest reason may be that investors have seen this movie before," the firm wrote.
