Question Of The Day: Most overlooked heroic engine?

All of us know that the small-block Chevrolet V8 was a masterpiece of engineering that made the high-performance overhead-valve V8 affordable to the masses, and that the Mercedes-Benz OM617 diesel is basically immortal, and that the Toyota R engine defined what it means for a vehicle to be considered Warlord Grade. The AMC straight-six. The Model T engine. The Volvo Redblock. Those engines get the respect they deserve. But what about the engines that we don't think much about, the ones that worked hard in their millions and somehow missed attaining legend status? The list of engines beloved by their aficionados but not thought of often by the rest of us goes on and on: the Renault Ventoux, Mitsubishi 4G1, MeMZ-968, and so on. But my vote goes to the Chrysler flathead straight-six. This engine was produced starting in 1929 and was still being made for stationary industrial use in the early 1970s. It powered just about every type of Chrysler vehicle made for decades, hauled supplies for all the major Allied armies in World War II, and was even developed into a five-bank, 30-cylinder tank engine. It was simple and reliable and outlived most of its competition, and you rarely hear much about it these days. What's your choice?

Dodge Challenger spied exercising supercharged Hellcat Hemi V8

One of the prime complaints against the Dodge Challenger is that, even in SRT8 guise, its 470 horsepower is responsible for hauling over 4,200 pounds of vehicle. For comparison, the 420 hp in the Ford Mustang GT only has to deal with 3,618 lbs. Things only get worse from there, as the higher-performance variants of both the Mustang and the Chevrolet Camaro are far more powerful than an SRT8 without adding on much heft.
So what is Chrysler to do? The correct answer is add a whole lot more grunt to its hefty two-door and even the odds. That's where the all-new Hellcat engine comes into play. We reported on this engine in May, and suggested that the Hellcat, a supercharged powerplant based on a 6.4-liter V8, would easily generate 500 to 570 hp and could likely arrive boasting more than 600 ponies.
Chrysler's ace in its sleeve has now been spied testing, with a number of Hellcat-equipped Challengers running the potent new engine both in more urbanized areas and under the sun of Death Valley. The hoods on these testers have been raised to accommodate the engine, and that camouflage over the fascias of these prototypes is there to hide a larger air intake. We also note what appears to be a new split grille under wraps. As for power output, our spies are now suggesting a Viper-equalling 640 hp from the Hellcat-equipped cars.

You can own Don Draper's 1964 Imperial Crown Convertible

In AMC's Mad Men Jon Hamm's character may have been a jerk, but Don Draper's 1964 Imperial Crown Convertible is fantastic. One of just 922 droptop Imperials built for 1964, Draper's land yacht is up for auction as part of a broader sale of Mad Men props. Alongside stuff like Roger Sterling's Ray-Bans or Draper's copy of Dante Alighieri's Inferno, the big Imperial is the undisputed star of the show. According to the auction page, fewer than 200 exist today, meaning that even without its Hollywood provenance, this is an exceedingly rare vehicle. Under hood, there's a 413-cubic-inch V8 wedge mated up to a push-button, three-speed TorqueFlite automatic transmission. Typical of a big, 1960s luxury vehicle, the Imperial gets power steering, power brakes, and power windows. Even the roof is electric. Cosmetically, the auction site claims Draper's convertible was repainted once, 20 years ago, going from a "drab" Roman Dark Red to today's California Red. In the interior, the only change are new carpets. This isn't the first time Draper's Imperial has crossed the auction block. It sold at a Palm Springs auction in February 2015 for just $23,625, before a St. Louis dealership listed it on eBay for $39,900 less than a month later. That online listing has long since disappeared, so there's no telling if it actually sold or not before being listed as part of this latest auction. Regardless, with fewer than 1,000 made, fewer than 200 in existence, a credit on a critically acclaimed TV show, and a history of reasonable sale prices, this is one big, 1960s land yacht worth considering. The auction starts on June 1 and runs through June 15. Related Video:
