Editor’s Note: The year 2013 gave us the C7 Chevrolet Corvette and took from us performance legends like Dean Jeffries and Stu Hilborn. We had a light-hearted look at the half-dozen Fast and Furious movies and got serious with dozens and dozens of new tech articles and how-tos. We even put a hot rodder’s spin on March Madness and Fantasy Football. All told, there were over 550 new articles from OnAllCylinders in 2013.

Before we turn the calendar to ’14, we’re taking a look back at our most-popular, most-read articles of 2013. In case you missed them, here are the Top 5 tech projects covered on OnAllCylinders in 2013.

1. Factory Five/Summit Racing Mk4 Build (Part 4): Body Prep and Fitting Trim

We originally launched the MK4 build series in 2012, but it spilled over into 2013. The entire series proved to be wildly popular, and no single part of the project garnered most interest than part four: the body prep and trimwork. Read the post—and the entire series—to find out why.

2. Big Ford Horsepower (Part 1): Trick Flow Assembles a 598 Cubic Inches of Short Block

Apparently, 598 cubic inches will get your attention. It worked for Trick Flow Specialties as they put together a massive-cube big block Ford for the winner of the IHRA Summit Racing SuperSeries Top Class champion. What components did they use? Can you duplicate this build with off-the-shelf parts? And how much horsepower did it ultimately make? Read and see.

3. American Resto Mods and Summit Racing Team Up for Rutledge Wood’s 1949 Chevy Step Van Project

Take the creativity and charisma of Top Gear’s Rutledge Wood, add in parts from Summit Racing, and bring it all together with the hot rodding know-how of American Resto Mods. The end result: a unique project build that grabs your attention.

Rutledge Wood’s 1949 Step Van is anything but a typical hot rodding project, but it attracted a lot of eyeballs and conversation on the Power Tour, at SEMA—and here at OnAllCylinders.

4. Hardcore LS: LME’s 700-Horsepower LS Engine

LS motors are big. LS motors that can make 700 horsepower—well, that’s a concept that really resonated with our readers. In conjunction with Power AutoMedia, we followed this build up in step-by-step fashion to prove you can build a high-horsepower LS engine that’s capable of owning the track and playing nice on the street.

5. Demon on Wheels: Bringing an Old Ford 390FE Big Block Back to Life

What do you call a 600-horsepower Ford 390FE? A Demon on Wheels. That’s also the name of the documentary film that features the Ford 390FE and the 1968 Mustang GT that it lives in. Learn more about the engine project—and the entire documentary—in this post, which was our fifth most popular tech project of 2013.
