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.

Outrageous Thor24 semi truck to appear in the new season of 'Jay Leno's Garage'

Wednesday is Jay Leno's birthday, and CNBC used the occasion to announce the upcoming season of Jay Leno's Garage. In a new teaser video, Leno is seen with a stacked list of guests, some new, some repeats, as well as a wild gamut of vehicles, including the absolutely insane 24-cylinder, 3,424-horsepower Thor24.  The outrageous semi build, which sold at auction in Saudi Arabia earlier this year for a whopping $12 million (or $1 million per supercharger) will join the likes of the Tesla Cybertruck and a recliner on wheels on the upcoming season of Jay's series.  Thor24 View 24 Photos The formula for Jay Leno's Garage is simple, successful, and not changing anytime soon. He brings out a bunch of famous people, some of which are real enthusiasts, others who have more casual driving backgrounds, and they experience a vehicle together. In the short clip released by CNBC, Leno is accompanied by Elon Musk (again), Danny Trejo, Bill Burr, Tim Allen, Jon Hamm, Brad Garrett, Jeff Dunham, Kelly Clarkson, Matt LeBlanc, Blake Shelton, Norm MacDonald, Edd China, and Jon Lovitz.           View this post on Instagram                   Thank you for sharing your dream with us. Happy Birthday, Jay! Love always, your @cnbcprime Family. A post shared by Jay Leno's Garage (@jaylenosgarage) on Apr 28, 2020 at 8:27am PDT The people, however, are merely social lubricants to spotlight the real stars of the show, the cars. This season will include the Tesla Cybertruck, the record-breaking Bugatti Chiron Super Sport 300+, a 1965 Buick Riviera, a naked cat car, an Aston Martin DBS Superleggera, a Porsche Taycan, a modern Ford GT, a Chevrolet Corvette C8 hard-top convertible, amphicars, a snail car, a beetle car, a couch car, and the 24-cylinder, 12-supercharger, 3,424-horsepower Thor24 semi. Just to name a few. As usual, there will be racing, stunts, spinouts, smoke from both tires and engines, and lots of silly dad jokes. Season 5 of Jay Leno's Garage debuts on CNBC on May 20 at 10 p.m. ET.

No, Cadillac is not killing its flagship CT6 sedan

Mark Twain never actually said that reports of his death had been greatly exaggerated. But if the Cadillac CT6 could talk, those are the exact words it would use. Speaking to Jalopnik, Cadillac chief Johan de Nysschen confirmed, emphatically, "There is absolutely no plan, at all, to cancel the CT6." In fact, says de Nysschen, the CT6 will soon be the beneficiary of significant investment. "The [CT6] forms a very important part of our product strategy going forward for the brand. The car also has a very major contribution to make to the shaping of brand perceptions, and the transformational process that Cadillac is undergoing." For instance, expect the CT6 to spearhead General Motors' most advanced forays into self-driving automobile technology. Interestingly, though, the Cadillac ATS and CTS sedans probably won't live past their current generations as the automaker 're-balances its sedan portfolio.' Replacement models are "in development" right now, says de Nysschen, which will "much more clearly separate the market position, both in terms of target customer demographics, in terms of market segments and in terms of price points between these three sedan lineups." So, that's confirmation that the Cadillac CT6 is going to stick around for a while. But what of other models cited by Reuters to potentially be killed, like the Buick LaCrosse and Chevy Impala and Volt? Read our take on that here, but suffice it to say that we don't think they're in danger, either.
