You are looking at a 3,500 horsepower, 24-cylinder radial Pratt & Whitney Wasp Major engine, developed at the end of WWII for use in Boeing's successor to the Superfortress. It is mesmerizing.

You saw this coming, right? We argued over the merits of the best four-cylinder, the best inline six, and the best V8, and we'll get to the V6s, V12s, radials, and everything else... someday. Today, however, we choose the king.

Last winter, we asked for your opinions on the Most Legendary V8 Of All Freakin' Time and the Most Legendary Inline Six... and then I totally spaced on what may be the most important Legendary Engine question of all!

Engines manufactured by Continental 1920s and 1930s powered about four million cars, which seems moderately impressive. Read Daniel Strohl's list of Continental-powered marques, however, and you'll be floored!

As we continue to work on the Ultimate Engine Survivors Honor Roll, certain engines start to stand out for their incredibly long lifespans. Here's one that was built in some form from 1947 through at least 1997.

After the agonized debate over the most legendary inline six of all time, we have no choice but to roll this grenade into the room!

Now here's a QOTD that's sure to get the single-interest fanatics swinging their sabers at the neck-pipes of perceived infidels, but we're hoping that y'all can dredge up some, like, objectivity here: Which I6 engine is most legendary?

We honored the Pontiac OHC Six, which was based on the Chevrolet 230, a couple weeks back. Today, we honor the pushrod Chevy!

It isn't often that an engine makes the front page of Wikipedia, but not many engines score as high on the Ass-Kick-O-Meter™ as the Rolls-Royce R!

How would the Malaise Era have played out for The General if he hadn't given up on Pontiac's high-performance SOHC inline six of the mid-1960s?

The great thing about this series is that we're nowhere near running out of engines that were made by the millions, for decades. Ford's workhorse I6 racked up close to a quarter-century of front-line service, from 1960 to 1984.

A pushrod, carburetor-fed V8 from BMW? Sure, but you have to go back about a half-century.

After World War II ended, Americans knew what they wanted: overhead-valve V8s and plenty of them! It took a few years, but almost every manufacturer had one by the mid-1950s. Studebaker joined the V8 club in 1951.

We've already honored the Ford "Pinto" OHC engine here, but what about the pushrod four that served as the early Pinto's base engine?

After we had Engine Of The Day Overload last weekend, I got the usual flurry of emails pointing out the really important stuff I'd overlooked. One engine kept coming up, though: the mighty Toyota JZ!

We've been doing the Engine Of The Day series for a couple of years, so it's time we put all 74 EOTD honorees together!

If we ever get around to doing an Ultimate Engine Survivors list (to accompany the Survivor Cars list), this engine will surely be near the top. 47 years and counting!

With 20 years of service, installation in dozens of different vehicles, and an excellent racing record, the Nissan VG definitely deserves Engine Of The Day honors.

Two-stroke engines for cars have always been on the smoky and noisy side, but they sure do make a lot of power for their size!
