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.

Hurst Edition Trans Am proves the Screaming Chicken will rise from the ashes

It seems the Pontiac Trans Am steadfastly refuses to die. Ever since Chevrolet was granted a retrofied Camaro to compete with the Ford Mustang, Pontiac lovers have lamented the loss of this 1970s icon. And, looking at the Hurst Edition from Trans Am Depot, shown here at the 2012 SEMA Show, may explain what all the fuss is about.
It's not going to appeal to everyone's muscle-car tastes, but there's certainly room for a brash-and-bold black-and-gold Special Edition in many a Trans Am lover's garage. After all, if you want the keys to a custom pony car, you'll certainly get noticed in this one. If this scheme isn't your bag,, you can alternatively order your Hurst Edition in white and gold or silver and black. Oh, and don't forget a color-coordinated Screaming Chicken on the hood.
No matter which way you choose to go, your inner Burt Reynolds will appreciate the Eibach suspension kit, forged wheels with Pirelli PZero tires, functional shaker hood, fender air extractors, rear spoiler and, of course, a Hurst shifter inside. The interior is emblazoned with all manner of special touches, including a Hurst dash plate and T/A stitching on the Katzkin two-tone leather seats.

Chevy to resume engine-building program for 2015 Corvette Z06

One of Chevrolet's most popular and unique customer features is set to return for 2015, as the company has announced that the Engine Build Experience is back. Interested owners will be able to screw together their engines beginning in March. The $5,000 option (which does not include the cost of travel) will give future owners of the 2015 Corvette Z06 the chance to screw together their car's actual 6.2-liter, supercharged V8. Available on each of the Z06's three trims, the Engine Build Experience includes a day at the Performance Build Center, instruction from an engine assembly tech, photographs of the experience and a personalized engine plaque. Once the build process is completed, the engine will (eventually) be fitted under the hood of the customer's personal Z06. "Chevrolet recognizes the passion customers have for Corvette and the Engine Build Experience offers them a truly unique opportunity for hands-on involvement in the creation of the heart of their new car," Corvette product manager Harlan Charles. "It's important for customers to understand their engine won't be installed the day after they built it. It will flow into the scheduling process for vehicle assembly, which depends on a number of logistical variables." Scroll down for the official announcement of the Z06's Engine Build Experience, available below.
