LS swaps are so hot right now. Name a car, and you’re a two-second Google search away from finding images of the ubiquitous Chevy V8 shoved into an unsuspecting chassis. Any car you’re thinking about, it has already been done.
I appreciate the desire that leads one to swap motors in their vehicle. While huge horsepower gains are often the stated goal, the much larger elephant in the room is reliability. You can tune, tweak, and improve a lot of engines to at least 500 horsepower, but you generally introduce one vulnerability for every one horsepower you eke out. LS swapping gives you power for sure, but also a reliability that is hard to match.
