SME Stage 1 LS Blower All Aluminum Engine - 900+hp

We are now offering a Stage 1 LS3 Complete Engine Package.  This engine package is based off our normal LS3 package.  It features all of the machining, parts, and EFI system that is proven to make over 900+hp all on 93-octane pump gas!  This is perfect for your weekend warrior or street/strip muscle car.  We can build this to utilize either a Magnuson, Whipple or a Kenny Bell Supercharger to reach these power goals.

See the videos below for each.

This engine package will include an after market EFI system as standard to allow for full engine control and the best driving characteristics possible.  Most other suppliers of turn-key engine packages will use out-of-date MEFI ECM's and harnesses that do NOT allow the engine to make fueling or timing changes when running, nor will they allow for any needed changes with varying altitude.  This will not only help the power output, but it will also help to maximize the fuel mileage!  The HolleyEFI Or FuelTech systems have full data logging capabilities, and a color touch-screen display is also available.  We DO NOT use any remanufactured or junk-yard parts for our build.  This is all brand-new components.

This engine package is incredibly configurable.  Give us a call to discuss the many different combinations available.
