Top 10 LS Engine Articles

Shining the spotlight on GM’s uber-popular small-block powerplant

Oct 6, 2020
It's amazing how two simple letters—LS—can immediately identify one of the most revered engine platforms in automotive high performance. Technically, General Motors' cast-iron "LS" small-block is the V-8 powerplant used in all Chevrolet and GMC rear-wheel-drive cars and trucks.
With the exception of rod bearings, lifters and cylinder-bore spacing, the LS platform is completely different from its traditional (and iconic) small-block Chevy predecessor. The iron block is stronger, and the aluminum cylinder-head port design is much improved. However, there is a common denominator between old and LS. Like the 350-cubic-inch OG, LS engines can be modified to produce great amounts of horsepower and torque without requiring an enormous budget to get it done.
Truck enthusiasts and builders understand this benefit and have made the "LS motor" an unofficial go-to engine for repowering vintage Chevy C10 rigs and swapping into non-GM vehicles. In later-model pickups that are factory-equipped with the powerplant, replacing stock pieces with readily available aftermarket upgrades (especially camshafts and including superchargers and turbochargers, which also are extremely popular) has become the norm, transforming sedate, utilitarian rigs into mega-horsepower, pavement-pounding beasts.
When it comes to articles about "LS trucks," the TruckTrend online database is stacked. Here is a sampling of ten reports. Stay tuned for more because this hot topic definitely will be revisited.
