For over 60 years, Chevrolet’s Small Block 350 has been the gift that keeps on giving, thanks in large part to its ability to provide incomparable bang-for-your-buck performance. But it wasn’t until 1988 when Chevrolet really flipped the script when it released the “ZZZ,” the company’s first modern crate engine. Despite not being as large and as powerful as some of the other crate engines released at that time, the ZZZ received universal acclaim for its all-around versatility. Since then, the ZZ-series crate engine has evolved numerous times. It will culminate at the 2015 SEMA Auto Show, when Chevrolet Performance unveils the latest iteration of the iconic powertrain, the new ZZ6 350-cubic-inch, 5.7-liter crate engine.
The ZZ6 is fresh out of Chevrolet’s engine laboratory, boasting new features that are expected to take its performance capabilities to a whole new level. One of the most important features of the engine are the updated Fast Burn cylinder heads with large intake runners and 2.00/1.55-inch valves, both of which play integral roles in facilitating increased airflow, enhancing the engine’s performance in high-rpm situations, and helping the new mill produce 405 horsepower and 405 pound-feet of torque. Those performance numbers represent the most power ever produced by a "stock" Chevy 350 engine, making the new ZZ6 one of the most powerful Small Block 350 crate engines in the entire history of the ZZ powertrain.
In a lot of ways, this new engine represents Chevrolet’s ability to evolve and adapt to the current crate engine climate, all while sticking to an architecture that has served it well since the first Small Block 350 burst into the scene back in 1955. Once the new ZZ6 crate engine hits the market, potential customers have the option to choose between two versions: Base and Turn Key. Chevrolet has yet to announce the price for the new ZZ6 crate engine kits but expect an announcement to be made at SEMA on November 3, 2015.

General Motors has been offering an automatic locking rear differential in its Chevy and GMC trucks for more than 40 years. Today, its prevalence has grown to include every body-on-frame, rear-drive vehicle in GM’s lineup – from the Colorado WT up through the leather-lined Cadillac Escalade. And thanks to its order code, most folks know the mechanical locker as the Eaton G80. Here’s how it works.
The G80 is a specialized differential designed by Eaton to work as a low-speed traction aid, offering full lockup during its operation. When in normal conditions, the unit acts as an open differential, letting the rear tires spin independently of each other, with the outside wheel spinning faster during turns. However, when one tire spins 120 rpm faster than the other, the G80 locker kicks into action.
As the video above shows, the difference in rpm actuates a flyweight-type governor, slinging a pawl that engages a clutch system, which then causes a cam plate to ramp against a side gear, compressing the disc pack. This action locks together both axle shafts, and therefore makes both wheels rotate at the same speed. Eaton has included two such actuating pawls, allowing the G80 to work in both forward and reverse gears.
Simply put, the G80 engages automatically and without driver input to evenly distribute power both rear wheels. This is in contrast to other systems as Ford’s or Ram’s E-Lockers, which require the driver to engage the system electronically from the cabin. While there’s pros and cons to both systems, the Eaton G80 does take the cake for simplicity for the driver.

Chevrolet designed the Z/28 version of the Camaro to be a lightweight track boss with word-class credentials. Still, some feel its 505-horsepower, naturally aspirated 7.0-liter V-8 is underpowered, especially compared to its 580-horsepower ZL1 brother. Though the Z/28 has been on the market for a relatively short time, owners are already beginning to pour on the power.
Redline Motorsports in South Florida has already shown what’s possible. The speed shop threw on an Edelbrock supercharger, high-flow injectors, a performance camshaft complete with beefier valvetrain, and a full exhaust with two-inch diameter headers. Topping the build off is a full tune of the Z/28’s ECU, making all the added parts work together.
The result was a full 197 horsepower and 208 pound-feet of torque added to the Camaro’s baseline dyno run. That translates into an impressive 652 horsepower and 628 pound-feet of torque at the wheels. No doubt its 0-60 mph time will drop below the 4.0 seconds it takes a stock Z/28.
Many anniversaries have been celebrated in the automotive industry in recent years, but perhaps none has been as crucial for those on a budget as the 60th anniversary of the Chevrolet small-block V-8. First introduced in 1955, this engine is known for its ability to fit into just about any car imaginable and the ease with which it can be repaired or rebuilt. To show what goes in to rebuilding one of these engines, Hagerty Classic Cars has created an amazing time-lapse video to celebrate Chevy’s small-block.
Just like any one of us would have to deal with, the video starts with a greasy, dirty and worn-out V-8, and it shows the entire process from beginning to end. Now, if you’re sitting there with a small-block Chevy V-8 sitting in your garage needing a rebuild, just be ready to put in some hard work.
Although the video isn’t even four minutes long, Hagerty says that it took roughly 60-80 man hours (including extra time for the video shoot) from start to finish. This includes a total of 16 hours just to tear the engine block down and later reassemble it, six hours for porting the heads, four hours for cleaning and prepping the block and another five hours for final assembly (intake, water pump, exhaust manifold, etc.). And this is just the time that Hagerty’s guys put into it… the engine spent another two days at a machine shop and a day at the paint booth.
After all that work, we were left wondering what the fate of this rebuilt engine will be? To answer that, Hagerty says it will go back under the same hood of the 1970 Chevrolet Impala convertible from which it came.
Although we’re just dying to meddle with the upcoming Corvette Z06 in Chevy’s online configurator, we won’t be able to do that for a few more months, as the utterly powerful Vette won’t go on sale until early 2015. However, thanks to Corvette Blogger, we now have access to the supercar’s order guide and all the standard and optional features that come with it.
Besides revealing the Z06’s exterior and interior amenities, the order guide also tells us that the beefed-up C7 model tips the scales at 3,524 in Coupe guise and at 3,582 pounds with a fabric top. That’s quite a lot considering the vehicle’s lightweight, race-inspired aluminum structure, but explainable by the amount of technology it comes with. All told, the C7 Z06 Coupe is 349 pounds heavier than its predecessor, which weighed in at 3,175 pounds.
The extra pounds shouldn’t be a problem though, as the brand-new Z06 carries no less than 650 horsepower and 650 pound-feet of torque under the hood, a 145-pony and 180-pound-feet bump over the previous generation model.

Remember last month’s report saying Chevrolet will restrict an array of Camaro Z/28 parts to prevent aftermarket cloning and preserve the muscle car’s exclusivity? It was all but good news to customers hoping Chevy will release a few visual and drivetrain Z/28 upgrades for the regular Camaros.
Well, we’re back on the matter to let you know that GM will eventually offer nine performance packages that will add some Z/28 bells and whistles to the regular Bowtie-badged pony car. That’s the word from Car and Driver, who adds that some of the bundles will also feature parts that aren’t available as individual components.
Specifically, the Z/28 suspension kit will also come with spool-valve dampers, springs, and anti-roll bars, while the helical differential will be paired with an integrated heat exchanger. Additionally, drivers owning a 2012 model year or newer Camaro will also be able to order the Z/28’s cold-air intake, exhaust manifold (V-8 models only), brake cooling ducts, cat-back exhaust, and Recaro Seats.
What’s more, it appears that Chevy is also rolling out a body package that includes the Z/28’s front splitter, rear spoiler, and underbody tray that allows users to take their Camaro even closer to the Z/28 in terms of aesthetics. Of course, they won’t be able to build a perfect clone of the Z/28 without a crate engine and the parts Chevrolet has restricted, but it’s better than nothing, right?
Pricing for these packages is not available yet, but we’ll be right back as soon as Chevy Performance spills the beans.

Wintertime is quickly approaching, and the last thing you want to do is drive your $250k supercar or $52 million classic racer through snow, slush and salt. So, unless you live here in sunny Florida or Southern Cali, your only real option is to load you precious in a storage garage, and park it for the season.
The issue in storing a car for months on end is that the fuel system can get excessive moisture in it, causing rusting in the tank, and the fuel-injection system or carburetor can get gummed up from oxygen attacking the fuel. You could drain the tank, but then you run the risk of even more water infiltrating the fuel system, plus the rubber seals in the fuel system, which are designed for constant contact submersion in fuel, can dry up and start leaking when you fire up the engine for the first time.
So, you may be in a panic now, but we do have a solution. Fill your tank 95 percent full with your favorite fuel and add the prescribed amount of STA-BIL “Storage” Fuel Stabilizer to the gas tank. After adding STA-BIL to the tank, run the car for a few minutes to circulate it through the fuel system. Then, your good ol’ girl is ready for hibernation. Come springtime, when you crack open the storage unit, you will be instantly greeted by the old familiar rumble of your car’s engine without even a hint of a stumble from bad fuel, varnish or water in the system.
What’s more, STA-BIL is good for storage periods longer than just one season. In fact, it will continue working hard to keep your car’s fuel system in top shape for up to 12 months.
Additionally right now, STA-BIL is offering fans on Facebook a chance to win an $800 storage shed and STA-BIL product by simply sharing a storage tip, experience or nightmare here and a simple “like” of their Facebook page. Good luck!
Back in 1967, the RS Appearance Package for the Chevrolet Camaro included something that has since become one of the more desirable features on classic Camaros: hidden headlights. When you turned on the headlights, the doors opened and when the lights went off, the doors closed, giving the grille a sleek look. Sure they were loud, clucky and malfunctioned after 20,000 miles, but damn they were cool. Well, Forgiato is bringing headlight doors back to the Camaro with its DiFalco Retractable Hidden Headlight Grille.
This isn’t a joke, folks. Forgiato, known more for its fine wheels than anything else, has developed a unique matte-black-finished grille that comes with brushed stainless steel accent trim and shuttered LED-accented headlight covers. In terms of its design the grille really does stand out on its own merit, thanks to a simple black mesh grille insert with the distinctive white "F" Forgiato logo. The grille treatment continues in the lower aperture with black mesh that is trimmed in white.
But the real moneymaker, as far as this retro accessory is concerned, are the headlight covers, which have been have their own horizontal LED accent lighting that is reminiscent of the first-gen cover’s horizontal chrome accents. As soon as the driver switches on the headlights, headlight covers open up, revealing the standard headlight and turn signals behind it.
The accessory will cost $3,399, a pretty price to pay, but you can rest assured that few will have a Camaro as retro-looking as yours. The DiFalco Retractable Hidden Headlight Grille is available for LS, SS, and ZL1 Camaro models.
This could be the perfect gift for a loved one that wants to add a little first-gen styling to his modern Camaro. The real question is whether you are prepared to shell out over $3K for said gift…

Chevrolet has just announced the information on the 2014 Corvette’s all-new engine. This new powerplant is a 6.2-liter V-8 --- not the 5.5-liter that everyone was thinking – and it boasts loads of technical goodies that make it better than any engine the mighty `Vette has ever had.
Allow us to introduce you to the all-new LT1 Gen V engine, which pumps out an impressive 450 horsepower at 6,000 rpm and 450 pound-feet of torque at 4,000 rpm – that’s a 20-horsepower and 26 pound-feet increase over the outgoing 6.2-liter. One thing that GM did not change up is the fact that the LT1 Gen V engine will retain the OHV and cam-in-block configuration that the small block engines before it did. Yeah, we know, a little dated, but if it works for GM’s engineers then so be it.
Hit the jump for a detailed analysis of the new Chevrolet LT1 V8 engine for the Corvette C7.
Just yesterday, Chevrolet announced that the seventh generation Corvette will be making its world debut on January 13th at the Detroit Auto Show. Today, new details about the future sports car have popped up. According to British magazine, AutoCar, the C7 Corvette could feature a new twin-turbo V6 alongside new and traditional V8 engines.
Chevrolet is tweaking the power offerings of the Corvette by introducing a new 5.5 liter V8 engine as an entry-level version, while the current 6.2 liter V8 engine will be offered for its top versions. The new 5.5 liter engine will feature an aluminum block and will adopt higher compression and direct injection.
Next to these two engines, Chevrolet could introduce a downsized twin-turbo V6 that will deliver the same output of a V8 engine, but be much more fuel efficient. This new V6 version, however, will join the line-up at a later date.
Aside from the engine tweaks, the next Corvette will offer a significant weight reduction thanks to its new carbon fiber panels, replacing the fiber glass currently used. The model will remain a front-engined vehicle and will send its power to the rear wheels.
At this point, we still have a few more months before Chevrolet unveils the seventh generation Corvette, so any little details that escape the lips of a source close to the project are more than welcome. Today, we were able to snag a few pictures, albeit blurry ones, that reveal the power source of the iconic American sports car, as well as other little odds and ends.
A member of Corvette Forum uploaded these images showing that the C7 Corvette will be offered with air conditioned seats, similar to those already offered in the C6 Corvette. It will also feature standard 19" wheels on the front and 20" for the rear, as well as front park assist and a coupe removable roof with optional carbon fiber.
The most interesting images are the ones that highlight the engines being prepared for the Corvette. According to this post, the next Corvette will be offered with an LT1 engine at launch, while an additional LT4 will be available in 2014. Speculations reveal that the LT1 will deliver between 480-500 HP, while the LT4 will be an upgraded version of the engine offered in the Corvette ZL1 producing between 560-580 HP.
In the modern era of automobiles, most customers want to have their cake and eat it too, meaning they not only want great fuel economy and a low price, but they also want a well-performing vehicle. Enter the 2012 Chevrolet Sonic with a 1.8-liter four cylinder engine that gets a respectable 25 to 26 mpg in the city and 35 mpg on the highway. This is all well and good, but what about those looking for more miles per gallon.
Greater miles per gallon is the exact purpose for Chevy offering an optional 1.4-liter engine. Instinctively, you may assume that this more fuel efficient 1.4-liter engine may require a sacrifice of power, but GM bolted a turbocharger onto this Ecotec engine, boosting it to the same 138 horsepower as the 1.8-liter. It also produces 23 more pound-feet of torque than the larger 1.8-liter engine. In addition to its added torque, this boosted 1.4-liter gets 33 mpg in the city and 40 mpg on the highway, and zips the Sonic from 0 to 60 mph in just 7.8 seconds – we’re not talking a Ferrari, but that’s still impressive.
Unfortunately, for those that desired an automatic transmission, the turbo 1.4-liter engine was not an option, as it was only available with a six-speed manual transmission. Well, GM decided to answer the demand for an auto-equipped Sonic turbo, as the auto giant announced that it will now offer an optional six-speed automatic transmission on the 2012 Sonic Turbo. This new turbocharged, automatic-equipped 2012 Sonic will accelerate to 60 mph in eight seconds, per GM, which is significantly faster than its closest competitors, which include the Ford Fiesta, Honda Fit, and Hyundai Accent.
On top of the impressive acceleration time, the auto equipped Sonic turbo will get you 27 mpg in the city and 37 mpg on the highway. All of these features combined, plus the 2012 Sonic’s modern and stylish exterior, make us wonder why you are still reading this and not picking one up now… Or are we talking to ourselves here?

We already know that Chevrolet has started the working on the next generation Camaro, but today, Al Oppenheiser, Camaro’s Chief Engineer, is offering up new details on the car that is due in the fall of 2015. According to him, the new Camaro will get a choice of smaller engines and will most likely be lighter compared to the current generation, but the company will try to keep its design untouched.
"We always get hammered for mass, and that’s not going to be getting easier going forward. Displacement, number of cylinders, all of these things you need to think about."
The timing for this new Camaro shouldn’t be at all surprising considering Ford is already preparing a facelift Mustang for 2015 with an exterior update and either a turbocharged V6 or even a turbo 4-cylinder. Chevrolet’s target will be to stay as successful as they currently are: "We always have to stay fresh and ahead. [But] we do not want to lose the fact that we have nearly 40 percent of the market."
The full-on Chevrolet Sonic SEMA onslaught figures to go full-steam ahead with the introduction of more models that have been customized to high heavens by the boys at Chevy. One new piece is the Sonic Boom Concept, a car that Chevy cranked up with a sound system-based concept, delivering the kind of boom-tastic thrills for audiophiles the world over.
In setting up the concept audio system on the Sonic Boom, Chevrolet and KICKER Audio drew inspiration from the design of jet engines, emulating their style in the shape and positioning of the components. A high-tech head unit controls the system, which features a pair of 15-inch Comp VX subwoofers, 12 six-inch QS Component speakers and tweeters, six QS Component speakers and tweeters, two IX1000.1 Mono subwoofer amps, four IX500.4 four-channel mid and high amps, and a ZXSUM8 summing interface signal processor. The whole setup is completed to deliver a total sound output of 4,000 watts.
To keep the Sonic’s interior as fresh as can be, Chevy also added a bevy interior modifications, including custom-fabricated rear speaker enclosures and custom load floor, perforated black suede seat inserts, liquid metal trim pieces, a Jet Black leather-wrapped instrument panel with distressed leather inserts and red piping, and a Jet Black leather-wrapped flat-bottom steering wheel with distressed leather and red stitching.
As for the exterior, Chevrolet dressed up the Sonic with an anodized Sonic Boom Red exterior color with custom body graphics, window tint graphics, tinted front headlamps with Boom logo, a Concept Z-Spec grille, a Concept Z-Spec spoiler, and a new set of 19" wheels.
UPDATE 11/08/2011: We have added new images from the 2011 SEMA Auto Show. Check them out in the picture gallery provided!
As one of Chevrolet’s most popular cars on the market today, the Cruze compact sedan has developed quite a following over the past few years. So with its popularity continuously ascending, it was an obvious choice for Chevrolet to bring a couple of customized models to the 2011 SEMA Auto Show.
One of the models is the Chevrolet Cruze Z-Spec. You might recall that a year ago, Chevy rolled out the Cruze Z-Spec Concept at the 2010 SEMA Auto Show. That particular model came with its share of accessories, including a full plastic bodykit made up of front and rear bumper add-ons, side skirts, and a rear spoiler.
This particular model, on the other hand, will carry its own set of custom parts, including a high-flow grille, an accessory spoiler, a new stripe package, and a set of 18" custom wheels. Inside, the modifications done on the car comprise of a new steering wheel, special seat inserts, a racing-style pedal kit, an accessory shift knob, and a unique interior trim, among others.
There’s no indication as to whether this particular Cruze Z-Spec will be anything like the one we saw last year, but the good news is that we won’t have to wait too long to find out. The 2011 SEMA Auto Show opens its doors on November 1, giving us only a few sleepless nights to ponder over it.
Most automakers wait for a huge auto show to reveal updates for one of their more popular models, but Chevrolet is changing it up by presenting the 2012 updates for their beloved Corvette at the C5/C6 Bash at the National Corvette Museum. Luckily, the anticipation for a New York Auto Show reveal wasn’t a total bust as somehow or another the first details for the 2012 Corvette were revealed ahead of schedule. Now, Chevrolet is releasing the full spectrum of details just a few days before the vehicle’s grand reveal at the Museum extravaganza.
Most of the changes made to the Corvette show up in the Z06 and ZR1 models, with a new High Performance Package and a new Ultimate Performance Package. The only changes made across the Corvette board will be a host of interior modifications.
UPDATE 06/09/2011: A 2012 Corvette ZR1 equipped with new Michelin Pilot Sport Cup Zero Pressure tires has tackled the ZR1’s Nurburgring time set in 2008, shaving off more than six seconds. The ZR1’s new time of 7:19.63 gets that much closer to the record holding 7:18 run of the Porsche GT2 RS, but more importantly, provides the Corvette with ammo against the Dodge Viper ACR (7.19 seconds), the Nissan GTR (7:26.7), Ferrari Enzo (7:25.21), and the Pagani Zonda F Clubsport (7:24.44).
UPDATE 06/14/2011: Chevrolet has announced full specs and prices for the 2012 Corvette. And the bad news is that compared to the 2011 MY, the 2012 Corvette will be a little bit more expensive: prices will range from $49,525 for the base coupe version up to $111,525 for the ZR1 version. There is a price increase of about $480-$1,150 based on the model. Hit the jump for the full details. (CorvetteBlogger)

The Chevelle was one of the most successful nameplates in Chevrolet’s history. It was produced from 1964 to 1977 in three different generations and four distinct body styles: Coupe, Sedan, Convertible, and Station Wagon. With 34 years of Chevelle-less history, it was only a matter of time before someone thought it was a good idea to bring back the Chevelle in some sort of revival vehicle.
This blast from the past comes to us as the Chevrolet "Corvelle" and was put together by an unknown builder that thought it would be a great idea to combine the chassis from a 1968 Chevelle and just about everything else from a 2007 Corvette. Only 15% of the Chevelle was left when the Corvette’s components were added in and the end result is a seamless construction of two Chevrolet icons.
The Chevrolet Corvelle will be put up for auction by RK Motors for $109,900. It is painted in the same LeMans Blue that was available on the ’68 Chevelle and the ’07 Corvette. Power will comes from a 6.0 liter LS2 V8 engine that delivers 400 HP and 400 lb-ft of torque mated to a 6-speed manual transmission.

Back in 2010, Chevrolet launched a unique program called the Corvette Engine Build Experience. This program gave do-it-yourselfers the chance to build their very own engines for models like the Corvette ZR1 and the Corvette Z06. That’s right, for $5,800, customers got the chance to be a part of the building experience, kind of like those restaurants that let customers help cook their own food. Whether this program needed a more powerful marketing campaign or this guy truly wanted to take part in the experience, Rick Hendrick - one of the world’s foremost experts in NASCAR Sprint Cup Series racing - recently took the dive into auto manufacturing with a 7.0L 505-horsepower LS7 engine for his Corvette Z06 Carbon Edition.
"As a Chevy enthusiast and lifelong gearhead, having the chance to experience GM’s hand-build engine assembly is a real privilege," said Rick Hendrick, owner of Hendrick Motorsports. "I want to thank everyone at the Performance Build Center for this opportunity. It’s incredible to spend time with the people here and see first-hand these processes that produce some of the best engines in the world."
After Hendrick completes the engine build, his name will be put on a personalized nameplate that will be added to the engine before it goes to the Corvette assembly plant in Bowling Green, Ky. for installation. Although this does seem to be a marketing ploy to bring more attention to the program, we have to admit that the thought of building our very own engine is pretty enticing. We just didn’t need Hendrick to build his own for us to think so.
