What's Included

GM's LSx block is an engineering masterpiece. Strong yet lightweight, it's the perfect base for building engines for the street, strip and track.

We build to order, so if you need something special, call and ask. As a guide, though, we can sell you an LS1 complete engine, LS2, an LQ9 or LS3 — or, two variants each of the LS7, LSx and RHS. Whether you need a 454 LSx engine or something else, we have what you need.

A complete engine from us consists of the following:

  • Long block (assembled from top-quality American components and includes the heads)
  • Intake system (intake itself plus throttle body, injectors and fuel rail)
  • Ignition system 

In addition, all LSx complete engines leave our shop with a three-year, no-mileage limit warranty.

The LS engines for sale here, including the LSx 454, are engineered to be boost-ready. If you plan on adding a centrifugal or Roots-style supercharger, they'll take the load. (We can also custom-build for turbo applications).

With an in-house machine shop, plus balancing facilities and two dynamometers, we're fully equipped to build LSx boost-ready crate engines that are powerful and reliable. What's more, blueprinting is always part of the service.


Anyone seeking a Chevy LS complete engine for sale almost certainly wants more power. Our turnkey LSx engines and others will not disappoint. From the 550hp of an LS2 to the 800hp made by a 502ci RHS, these engines deliver outputs to match the beautiful sound they make. (Needless to say, when blown, you'll get much, much more).

Should anyone doubt your horsepower claims, we've got you covered. The LS engines we build go through our dyno test service before shipping. That gives you graphs listing horsepower and torque as well as other engine vitals.
