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.

Diesel-powered 2020 Chevrolet Silverado, GMC Sierra get big price cuts

General Motors is reducing the price difference between its diesel-powered light-duty pickups and their gasoline-burning counterparts, according to a recent report. As of September 3, 2020, the Chevrolet Silverado 1500 and the GMC Sierra 1500 benefit from a $1,500 price cut when they're ordered with a turbodiesel under the hood. Enthusiast website GM Authority first reported the news after looking at internal documents sent to dealers across the nation. It wrote the discount applies to in-stock and in-transit units of the Silverado and the Sierra (pictured), and it added dealers will begin receiving amended window stickers on September 8. And, it's not just a quick, easy way for General Motors stores to clear out 2020 inventory. Incoming 2021 models will benefit from it, too. Chevrolet's cheapest diesel-slurping 2020 Silverado, a double-cab LT with two-wheel drive, now starts at $44,000 once a mandatory $1,595 destination charge enters the equation. For context, the same configuration costs $38,795 including destination when it's ordered with the 2.7-liter turbocharged four-cylinder, which is the smallest and cheapest engine on the roster. Selecting the more efficient engine option costs buyers $5,205. At the other end of the spectrum, the crew-cab High Country with a standard cargo box and four-wheel drive is now priced at $59,690. Walk a block to the GMC store, and you'll need to spend between $44,470 (double-cab SLE with two-wheel drive) and $61,685 (crew-cab Denali with a regular cargo box and four-wheel drive) for a diesel-powered Sierra. It doesn't sound like either company is making major mechanical changes to the trucks for 2021. Both are powered by a 3.0-liter straight-six Duramax engine, which makes 277 horsepower and 460 pound-feet of torque. Rear-wheel drive and a 10-speed automatic transmission come standard, and four-wheel drive is offered at an extra cost. In its most efficient configuration, the Silverado returns 23 mpg in the city, 33 mpg on the highway, and 27 mpg in a mixed cycle, impressive numbers for a body-on-frmae pickup that's as heavy as it is capable. Ram's diesel-powered 1500 posts EPA estimates of 22, 32, and 26, respectively. Ford pledged the recently-unveiled 14th-generation F-150 will offer a turbodiesel engine, too, but its fuel economy figures are not available yet.

Electric Cadillac Lyriq, Chevy Bolt EUV and more GM electric cars are on the way

GM’s murky and somewhat secretive electric car plan is falling into place, as the company dumped a massive amount of information about whatÂ’s in the pipeline at an event at its Warren, Michigan campus today. New EVs are going to be popping up across the GM brand lineup, with new entries from Chevrolet, Cadillac, GMC and Buick in progress. We also learned some big news about GMÂ’s new Ultium battery tech today, but check out this story for all of those nitty-gritty details. The electric vehicle onslaught will begin with the Cadillac Lyriq, an electric SUV thatÂ’s already been teased out. Naming it the Lyriq is the news today. No explanation for the name was provided, so weÂ’ll have to wait for April to learn more. GM didnÂ’t specifically say if the Lyriq would be launched at the NY Auto Show, but that show (assuming coronavirus doesnÂ’t cancel it) will begin on April 8 this year. Next up in the order of events is the GMC Hummer electric truck that we know will be launching on May 20. This truck will use GMÂ’s modular Ultium battery technology. However, the wait to buy a GMC Hummer will be a long one, as the truck isnÂ’t going to dive into production until fall 2021 at GMÂ’s Detroit-Hamtramck plant. GM revealed that its new modular Ultium batteries can be configured anywhere from a 50 kWh pack to a 200 kWh pack depending on the application. Range is estimated to be about 400 miles on the upper end with the largest battery pack, and GM continues to boast about a 0-60 mph acceleration time of three seconds. Charging estimates for the Ultium battery-equipped Hummer EV were also provided. GM says its truck platform will have 800-volt battery packs and be capable of 350 kW fast-charging. Time estimates werenÂ’t given, but those numbers suggest the truck will be a rapid charger. The Hummer truck on hand, which was the same that previously starred in GMC's Super Bowl spot, showed off removable roof panels that store in the frunk, as well as what appeared to be a version of GMC's Multi-Pro tailgate. It also featured sail panels on the sides, similar to those in front of the bed of the Chevy Avalanche. In addition to the Hummer, expect to see a couple Chevys launching. GM says the refreshed Bolt EV will be launched “in late 2020” with a refreshed interior and what appear to be thicker front seats.
