GM's LS family of V8s is one of the most popular choices for engine swaps, hot rods, and custom car and truck projects of almost every kind. With a vast and deep aftermarket it's become cheap and easy to modify these motors for more horsepower if you decide that the stock output provided by Corvette and Camaro-sourced motors isn't enough to get you excited.
Given that Chevrolet and GMC also manufactured millions of trucks with LS engines under the hood, it's not at all difficult to find one to start playing with — or, on the flip side, find a truck with an LS already installed from the factory so you can start building your 4x4 off-road rig.
We've put together this resource that includes everything you could ever want to know about the LS V8 family.
