General Motors' LS engine is extremely popular, and that also applies to the 6.2-liter version. What do the owners and mechanics say? Is it good?

The new crate engines leverage the expertise of GM's LS engine program, but take it to the next level with race-caliber components.

When Lexus introduced the LS 430, its engine was an improvement on the one in the brand's pioneering LS 400, offering both more horsepower and more torque.

The "LS" designation, which stands for "Luxury Sport," perfectly encapsulates the potent blend of performance and sophistication that LSx engines deliver.

The hefty price tag won't be your only concern if you perform an LS engine swap on a square body truck; it might require more parts and labor than you expect.
