Pure Vision Design TT Camaro has 1,400 reasons to want it

We've talked about Pure Vision Design before, a California-based company that made waves at last year's SEMA show with its Martini-liveried, Indy-car-powered Ford Mustang. That same car later starred in a Petrolicious video we showed you just a few weeks back. The company's latest creation is a menacing car it calls the Pure Vision Design TT Camaro. Based on a 1972 model, this car shares the Martini Mustang's clean styling and obsession with details.
Unlike the Mustang, which draws its power from a mid-60s Lotus-Ford Indycar engine, the "TT" in this Camaro's name implies something far more potent. The Nelson Racing Engines 427-cubic-inch V8 has been fitted with a pair of turbochargers, with a claimed output of 1,400 horsepower. That's almost 1,000 more than the Martini Mustang.
A six-speed Magnum transmission dispatches that power to the ground, while Pirelli PZero tires are tasked with (somehow) trying to grip the road. Baer brakes hide behind those HRE rims, while JRI coilovers and HyperTech springs bless the Camaro with some degree of competency in the bends.

Camaro spy shots show subtly different grille, front fascia

It looks like there some changes in store for the Chevrolet Camaro - the only thing is that we just don't know what Chevy has up its sleeve. Looking at these spy shots, we'd initially be inclined to think that there is just a minor facelift or a new special edition, but upon closer inspection, there are a few oddities about this car that definitely have us intrigued.
The most obvious difference on this prototype is the slightly restyled front fascia with a smaller lower air inlet and the two-bar grille. Then we get to some of the car's mysterious details. For starters, this fascia has the SS vent above the grille, but it looks to be blocked off. Granted this could just be a one-off piece used for testing. What really piqued our interest was at the rear of the car where it has quad exhaust outlets that are used on the ZL1. Could this be the LS7-powered Camaro that we reported on back in December?
At this point, your guess is as good as ours as to what we're looking at here, so let us know in the comments what you think this could be.

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.
