This engine package is based off of our LSFree engine build.  It features all of the machining, parts, and EFI system that is proven to make over 900+hp 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 single (or twin) turbocharger or a supercharger to reach these power goals.

This package will include the following items:

  • New GM LS3/L92 Aluminum Engine Block
  • New GM 3.622" Stroke Crankshaft
  • Forged 4340  6.125" Connecting Rods with ARP2000 bolts
  • CP-Carrillo BULLET-Series forged piston package
  • Melling billet oil pump
  • RollMaster billet timing chain upgrade
  • New GM LS3 Cylinder Heads with Upgraded Single Beehive Valve Springs, upgraded valves, and LS Trunion Bushing kit
  • Steve Morris Engines Custom-Grind Hydraulic-Roller Camshaft
  • Steve Morris Engines custom 11/32" 0.120"-wall hardened pushrods
  • ARP main and head studs
  • MLS Cylinder Head Gaskets
  • GM LS3 Rocker Arm Kit
  • Brand New GM water pump and harmonic balancer
  • Drive-By-Wire Throttle Pedal and TB
  • Complete GM Sensors
  • New GM Ignition Coil Packs and plug wires
  • Holley EFI system with DBW controls
  • Competition machining and engine assembly
  • Engine dyno calibration
  • Enclosed engine crate and engine stand

This engine package will include an aftermarket 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  Most other suppliers of turn-key engine packages will use out-of-date MEFI ECM's and harnesses that do NOT allow the engine to make fueling or timing changes when running, nor will they allow for any needed changes with varying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 system can be upgraded to a DOMINATOR system, full datalogging 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.  We offer a 2% discount when paying by wire transfer or check.
