GM’s LS engine may be the hottest internal combustion engine in the last two decades, but that doesn’t mean it’s the only thing GM built that is worth building. The LT engine, the natural evolution of the LS, which features a few differences that make it unique is also a badass. Because of this there are of course folks who build hybrid versions where they are mixing and matching the best of each platform to make something special. Such is the case in this video where LT heads are going on an LS engine and the dyno is going to be put to work in order to see if this is a mod worth making.
