Mopar Hellephant crate engine sells out in 48 hours

This happened so quickly that we're only just catching up with it. Mopar opened pre-orders on the 7.0-liter Hellephant Hemi crate engine on April 26, which is Hemi Day. According to Allpar, hubbub on social media not long after that day claimed Mopar had gone through all of its Hellephant stock. When Allpar asked Fiat Chrysler for clarification, a spokesperson e-mailed, "Given the high demand and the hand-built, time-intensive build process, we have closed preordering for the 426 Hellephant Supercharged HEMI crate engine. Based on preorders, the engine sold out in just two days. Customers can visit www.cratehemi.com to receive future information and updates on the 'Hellephant' engine." No one is certain how many engines Mopar sold. Allpar wrote, "Industry insiders believe Mopar may be making around 100," but reiterated that it's a guess. The engine and the ordering process have their peculiarities. Mopar Insiders explained that Tool Engineering International helped create the 426-cubic-inch block, and that the Hellephant engine "shares nothing except for displacement with the rumored upcoming 7.0-liter 426 Hemi V8." On the Hellcat.org forum, a poster wrote that the engines "can only be sold through a dealer and that the dealers can only order 1 engine per week." The Hellephant doesn't come with Mopar's three-year, 100,000-mile warranty, either. During a press briefing last October, FCA officials said they weren't sure about offering any warranty. Based on the motor being given a part number starting with the letter P, there is a bit of protection, but it's a 90-day limited warranty covering "defects in materials or wokmanship," and only applies to engines not used in competition. For those who didn't get the opportunity to drop $29,995 for 1,000 horsepower and 950 pound-feet of torque, the best bet is to hope for the return of Apollyon's pachyderm. Motor1 wrote that "Rumors hint at... another limited run scheduled for next year due to overwhelming demand." That's thin thread to hang a Hellephant from, but it beats bupkis.

Junkyard Gem: 1991 Dodge Monaco LE

When Chrysler took over the American Motors Corporation in 1987, the hot-selling Jeep brand was the big prize of that deal. At a stroke, Iacocca's company got the XJ Cherokee (which remained in production into our current century) plus its Comanche pickup sibling, the Wrangler, the Grand Wagoneer, and the AMC Eagle as bonuses. The Eagle gave its name to Chrysler's new marque, which worked out well for quite a few years, and of course the PowerTech V8 engine began life as an AMC design. Yes, Chrysler made out like a bandit on the AMC purchase, but one of the most important acquisitions that came with that coup ended up being a Renault design from the last gasp of Kenosha: the Eagle Premier. Genetic material from this car made its way into Chrysler products for decades to come, and the Dodge Division got the opportunity to slap Monaco badges on the Premier for the 1990 through 1992 model years. Here's one of those super-rare cars in a Denver self-service yard. Dodge sold plenty of Detroit-designed Monacos from the 1965 through 1978 model years, and so the name seemed ripe for a revival in 1990. We rated the 1974 Dodge Monaco "Bluesmobile" #3 on the Best Movie Cars of All Time list, and Monacos may be found in countless cop movies and TV shows over the decades. Did the name belong on a Renault design? Absolutely! The radical-looking and big-selling Chrysler LH cars were built on a modified Eagle Premier chassis, enabling Chrysler to print money from a 1980s Renault design all the way through 2004. After that, Mercedes-Benz engineering (with a dash of Mitsubishi thrown in for good measure) got stirred into the mix, but I'm told by a Chrysler engineer that you can still see the Renault 25 structure beneath the dashboard in modern Challengers and Chargers. All of this comes thanks to Lee Iacocca's score of that advanced European car way back in 1987. One thing from the Premier that Chrysler dropped like a monkey dropping a red-hot penny once production of the Premier/Monaco ended: the PRV V6, a sophisticated-but-flaky overhead-cam V6 originally developed by a partnership between Peugeot, Renault, and Volvo (hence the acronym). This engine achieved its greatest fame as the powerplant that went into the DeLorean DMC-12. You could get the chugging AMC 2.5-liter straight-four in the Eagle Premier, but all the 1990-1992 Monacos got the 3.0-liter PRV, rated at 150 horsepower.

Chrysler almost smothered the Hellcat before it lived

Chrysler's 6.2-liter supercharged Hellcat V8 was an absolute sensation from the very moment it was announced, and honestly, how could it not have been? Packing 707 horsepower and 650 pound-feet of torque, its numbers immediately put every other production muscle car (and many supercars) to shame. Plus, we soon learned that would be wrapped in a package retailing for around $60,000 - a pittance compared to other vehicles offering similar grunt. However, the Hellcat almost never got the chance to rumble under the hood of the Challenger and Charger.
The Hellcat was initially proposed back in 2011, back when Fiat was deciding its future strategy for Chrysler Group, according to Automotive News. At the time, the company was just emerging from its bankruptcy doldrums, and an ultra-high-performance V8 wasn't exactly a must-have item. The program didn't move forward. However, SRT engineers kept fighting, according to AN, and four months later, they received the green light to pull the project off the shelf and continue developing the Hellcat. The muscle car world is certainly better for that decision.
The work of those engineers focused on taking Chrysler's standard 6.2-liter V8 and making it reliably handle all of the extra power from the supercharger. "It came down to micron levels of changes in the crank to be able to withstand the pressures of the engine," said Chris Cowland, director of advanced and SRT powertrain, to Automotive News. The changes amounted to switching out about 91 percent of the parts to make the Hellcat, including some quite minuscule alterations. For example, the washer holding the supercharger pulley is embedded with industrial diamonds to keep it from slipping.
