LS swaps are the overwhelming favorite power plant in this genre. They are relatively easy installs and deliver great $/hp in a small, lightweight package. Aesthetics are subjective. For purists, the typical LS looks out of place under the hood of their 1960-something Chevy. This engine is intended to bridge the aesthetic gap while still delivering tons of power with the reliability of fuel injection. The air…

Our immediate thought was that we could build it using a liquid-to-air intercooler sandwiched in a Holley intake manifold. That would make it plug-and-play. No issues of how to stuff a big air-to-air intake under the hood somewhere. We liked what we saw and ordered one on the spot. We picked the 10-rib version over…
