How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:

2015 Callaway Corvette Z06 gets new supercharger, adds $17K to starting price

Callaway's proud tradition of modifying Chevrolets is about to add a very significant chapter this weekend, as the company prepares to unveil a modified version of the 2015 Corvette Z06. The engine mods are simple, though we expect them to be very potent. That's because Chevy has replaced the factory supercharger with a new "GenThree" unit that's nearly a third larger than what's bolted on in Bowling Green. A new intercooler is also added, along with a new high-flow intake system. Beyond that, the changes are exclusively of the subtle cosmetic variety. There's new badging inside and out, as well as new engine covers, floormats and an underhood plaque. Naturally, there's documentation to verify the Callaway Z06's authenticity, and the comfort that comes with a three-year, 36,000-mile warranty. Callaway has priced the upgrade package at $16,995, in addition to the price of the stock Z06. While we're still waiting to hear official power figures, that seems like a reasonable asking price for what were wagering will be a major increase in power. The Callaway Z06 will debut this weekend at the National Corvette Museum's C7 Bash in Bowling Green, KY. Expect more details following the debut. Scroll down for the official press release.

Here's a sneak peek at the new package. Based on Chevrolet's track-proven Z06, Callaway engineers' no-compromise approach takes this Corvette to an astounding power level. While advertised Callaway horsepower and torque are pending final validation, the Callaway package adds Callaway's new GenThree supercharger system with 32% more displacement than the stock Z06 supercharger, improved manifold design and unique triple-element intercooling system. Callaway engineers recognize that a key contributor to maximizing power is reduction of inlet air temperature. By exposing the supercharger's large plenum area to outside ambient airflow, the design takes advantage of the significant charge air temperature reduction provided by convective cooling. The completely redesigned intercooling system also helps maintain nearly ambient charge air temperature with exceptionally low air restriction.

GM: Without LG Chem, we couldn't build Bolt EV [UPDATE]

It's absolutely no surprise that General Motors has a thing for LG Corp. The Detroit automaker and the Korean parts supplier have been working in public on electric vehicles ever since it was announced that LG Chem would supply the battery cells for the Chevy Volt in 2009. LG Chem was even named GM's 2010 Supplier of the Year. But, yesterday, the connection between the two companies was strengthened with the announcement that LG Electronics would be supplying a number of components for the upcoming Chevy Bolt electric vehicle. The Bolt is expected to be able to go about 200 miles and will carry a price tag of about $30,000 (after incentives) when it arrives in 2017 or so. LG's new components can be found almost everywhere in the Bolt. They include the battery pack and the battery heater, a new motor, the power inverter module, the electric climate control system compressor, the on-board charger, high-power distribution module, the accessory power module, and power line communication module. Oh, and then there are LG Electronics' advanced display technologies like the new instrument cluster and a new infotainment cluster. LG Electronics also supplies parts for the 4G LTE OnStar system, just like it does in other new Chevys. If that all sounds like a lot of components to you, you're right. Mark Reuss, GM executive vice president of global product development, purchasing and supply chain, said that without the expanded relationship with LG, GM would not be able to bring the Bolt to market (insert old ironic quote link here). "I think GM was lacking that [electrification knowledge] in a very complete way for many years, I'll just be frank about that," Reuss said. "I also think that on an electrified basis, this requires a long-term commitment and trust that sometimes is violated on a more short-term, regular, traditional basis. I think we have found something completely different with LG and I think that has become a widely talked about and duplicated want from our purchasing and corporate standpoint with our supply base." The "this" that Reuss is talking about here is the OEM-supplier relationship, something has evolved with the LG-GM situation. Previously, the automaker-supplier relationship used to be more like a dictator telling underlings what he needed, Reuss said, and that was a bad idea. "Today's competitive landscape requires a different approach, especially in electrified vehicles," he said.
