Watch President Obama drive a Corvette around the White House

The season seven premiere of Jerry Seinfeld's web series Comedians in Cars Getting Coffee went live tonight on Crackle featuring the show's biggest guest so far. Yes, that's President Barack Obama driving a car around his front lawn. Seinfeld brings a classic Vette – a '63 split-window coupe with a 327 V8 and a stick!– to 1600 Pennsylvania Avenue for the president to ride in and later drive in a circle. Though they don't leave the White House grounds and barely break a walking pace, Obama seems to enjoy the rare event. For the caffeinated portion of the episode, the president and Seinfeld sit down in the White House's staff dining room. They chat about the usual stuff – celebrity status, the seat warmers in The Beast, their daily routines, and cursing. The video meant to be presented here is no longer available. Sorry for the inconvenience. From Crackle: Just Tell Him You're the President This is likely one of few times during Obama's two terms in office that he will get behind the wheel of a car. His VP Biden is no doubt jealous, as he owns a '67 Corvette 327 that the Secret Service won't let him drive. And yes, we realize Obama is not a comedian. There's probably a joke there, but we are not going to make it. Humor Chevrolet Videos jerry seinfeld comedians in cars getting coffee

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.

Chevy's 6.6-liter Duramax is pretty much all new

To say there's a heated battle in heavy-duty pickups is an understatement, with Chevrolet, Ford, and Ram constantly trading blows of increased torque, horsepower, and towing capacity. The latest salvo is the revised, more powerful turbo diesel 6.6-liter Duramax V8 in the 2017 Chevy Silverado. It has 910 pound-feet of torque, an increase of 145, putting it nearly level with the Ford Super Duty. Here's a closer look at where those gains come from. How exactly did Chevrolet add all that torque plus 48 horsepower? The automaker essentially took a fine-tooth comb to the entire engine. Chevy says it changed 90 percent of the V8, and the cumulative effect of those small changes adds up to big increases. As you might guess, the turbocharger is updated. The larger unit features electric actuation of the variable nozzle turbine (VNT), and what Chevy calls a double axle cartridge mechanism that separates the VNT moving parts from the housing. That helps with heat performance as well, with a claim that the exhaust side of the turbo can run continuously up to 1,436 degrees Fahrenheit. Helping that cause are six exhaust gaskets made of Inconel - an nickel alloy that contains chromium and iron – and upgraded stainless steel for the exhaust manifold. Despite having the same cast iron cylinder block, albeit with some minor enhancements, the engine has new cylinder heads, pistons, piston pins, connecting rods, and crankshaft, which have all been upgraded to handle 20 percent higher cylinder pressures. Alongside the increase in pressure, Chevrolet also increased the cylinder head's structure with a honeycomb design. The pattern features high-strength aluminum with dual layer water jackets that not only improve strength, but also optimize water flow for better cooling. For 2017, the cylinder head also benefits from integrated plenum that aids the engine in getting more air under heavy loads. The cylinder head isn't the only component to get a minor update, as the pistons have a larger diameter pin for improved oil flow. The same detailed improvements has been bestowed to the humble connecting rods (second in our hearts only to the inanimate carbon rod). The new design has the bolts oriented roughly 45-degrees to the rod instead of parallel. The angle split design, as it's called allows for easier passage through the cylinder.
