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.

NHTSA closes 4-year GM investigation, issues common sense advisory [w/video]

Since January 2011, the National Highway Traffic Safety Administration has been investigating a possible problem with corroding brake lines in General Motors' GMT800-platform models, like the Chevrolet Silverado and Suburban and GMC Sierra, in states with salt on their roads in the winter. However, as opposed to launching a full recall of millions of vehicles, the government is issuing a common-sense safety advisory to all drivers in snowy states to keep their vehicle's undercarriage clean. It even has a video explaining things. "Older-model vehicles, often driven in harsh conditions, are subject to corrosion over long periods of time, and we need owners to be vigilant about ensuring they, their passengers, and others on the roads are safe," said NHTSA Administrator Mark Rosekind in the announcement of the end of the investigation. The agency was clear in its report that "brake line corrosion seen in the GM vehicles was not unique," and the government "has not identified a defect that would initiate a recall order." Instead NHTSA is advising drivers, especially those of vehicles from before 2007, to wash their vehicle's undercarriage in the winter and spring to remove salt or other de-icing chemicals. It also recommends regular checks by a mechanic to make sure everything is in proper order. According to the investigation documents, for just the GMT800 platform models, NHTSA found 3,645 complaints of brake line corrosion, which included allegations of 107 crashes and 40 injuries. The issue was found to be more common in vehicles over 10 years old. GM has released a statement (embedded below) that the company "supports the consumer advisory from NHTSA urging regular maintenance and care of brake lines on older vehicles." NHTSA Closes Investigation into Brake-Line Failures NHTSA 13-15 Thursday, April 9, 2015 Agency issues safety advisory on preventing undercarriage corrosion WASHINGTON – The Department of Transportation's National Highway Traffic Safety Administration (NHTSA) today issued a Safety Advisory and consumer video encouraging owners of model year 2007 and older trucks, SUVs and passenger cars to inspect brake lines and thoroughly wash the underside of their vehicles to remove corrosive salt after the long winter in order to prevent brake-line failures that increase the risk of a crash.

GM is quietly slashing prices on base models

While General Motors' fourth quarter financial figures haven't yet been released, the automaker seems to be weathering a potentially rocky time well, even beating third-quarter projections last year. To keep the climb going, the company is launching new base trims for several popular models that make them cheaper than ever but with tight dealer margins. The new entry-level trims are the Chevrolet Cruze L, Equinox L, GMC Terrain SL and Buick LaCrosse 1SV. Buyers lose some content by picking them, but the prices are slashed. According to Cars Direct, the biggest savings are on the LaCrosse, where customers pay $31,065, plus $925 destination, $2,570 less than the previous base 1SB trim but must accept things like 17-inch wheels and no cargo net in the back. If you're wondering how Buick can remove only a little equipment but cut the price so much, it's because the company also slashed dealer margins. According to Cars Direct, the difference between the invoice and MSRP for the LaCrosse 1SV is only around $150, compared to around $1,350 before. The disparity is even greater for the Cruze with an $81 difference in the prices, compared to about $600 for the LS version. Showrooms are expected to keep very low stocks of these trims, though. "Dealers use such vehicles to get people in the door, but they do not generally want to do high volumes of these strippers. The margins are next to nothing; they don't make much money off these cars," said Ed Kim, Vice President of Industry Analysis for AutoPacific to Autoblog. Dealers are also expected to advertise that these new base trims undercut major competitors. For example, the Cruze L rings up for about $2,320 less than a Honda Civic LX, according to Cars Direct. One potential drawback for buyers is that these models might not be eligible for incentives. While the attractive prices might get customers into dealers, folks may not actually end up driving home with these entry-level models. Kim indicated base trims also make up a small portion of the sales mix. "Consumers aren't asking for stripped out vehicles, even at the low end of the marketplace," he said.
