The compact size and lightweight construction make it an excellent fit for a variety of vehicles, from muscle cars to trucks. Kits are readily available to help you fit an LS engine into almost any chassis, making it a popular choice for custom builds.

Fuel Efficiency

While performance is often the focus, it’s worth noting that many LS engines are surprisingly fuel-efficient, especially when compared to older V8s. This makes them a practical choice for those who want power without sacrificing daily drivability.
