Has there ever been more universal engine solution than the Chevrolet LS V-8? It’s compact, it makes a lot of power even in stock tune, it’s reliable, and General Motors made a number of different variations in vast quantities. LS-based power has become such a default engine swap choice that it almost seems like cheating. There is a reason for its popularity, though, or even many reasons. Primarily: the Chevy Small block can fit in almost any engine bay. From junkyard finds to brand-new, emissions-certified plug-and-play crate engines from the GM Performance Parts engines, there’s one for every budget. And there are plenty of tune-up parts.
