This is the age of horsepower. Power masters build giant-cube big-blocks and play with exotic CNC-machined billet blocks with custom bore centers, tomato-can-sized bores, and yard-length strokes. But on the other end of the scale is a new army of small-displacement production V-8 engines capable of amazing power numbers. We had rescued a 5.3L truck

Preceding the modern Hemi, traditional Mopar V-8 power relied upon the updated and rehashed Magnum series of small-blocks. Good old 318 and 360 engines with roots going back to 1964, the Magnums were an anachronism in the modern world. The new Hemi pulled the stops on technology, with the crowning touch being those all-important Hemi

Ford created quite a buzz of excitement in late 2019, when it revealed that an all-new 7.3L V-8 gas engine would be the standard powerplant for its 2020 Super Duty lineup. As traditional pushrod engines go, big cubic inches (445 for the 7.3L) and the torque they create are highly desirable in vehicles like pickups

It’s a bit sad, but the state of the automotive industry in 2021 is leaning more toward highly efficient small-displacement engines instead of the burly V-8s of old. Thankfully, these beasts of burden haven’t been fully forgotten, and you can still get a great V-8 engine with decent fuel economy and loads of torque from

Here is a tip for LS enthusiasts out there: If the question ever arises about how to make an LS better, your go-to response should always be swap the cam! Sure, cylinder heads and intake manifolds are most welcome (especially on cathedral-port applications), but their gains are all but dependent on the presence of wilder-than-stock

Continuing our informal “series” on diesel-engine problems—common, and, not-so-common—we’re focusing our attention on the Ford 6.7L Power Stroke (code name “Scorpion”), an engine developed exclusively by Ford engineers and assembled completely in-house that’s used in Super Duty rigs from 2011 to today. The “six-seven” has proven itself to be a good engine in the near-decade

We add more power to a 2002 GMC Sierra with a 5.3L LS engine using bolt-on parts.
