2 "Warning:Caution must be observed when installing any productinvolving fuel system parts or gas tank modifications. Work in awell ventilated area with an approved fire extinguisher readily avail-able. Eye protection and other safety apparel should be worn to pro-tect against debris and sprayed gasoline. Be sure to disconnect thenegative terminal of the battery before beginning. We recommendhaving this installation performed by an experienced, qualified, andFiTech approved automotive technician. The finished installationmust be thoroughly checked for any fuel system leaks.

3 All safetyprecautions must be observed when working with fuel. Lastly, en-sure the engine has had sufficient time to cool! The coolant maystill be hot. Disregarding any of this information can result in seri-ous injury or Status: FiTech s Ultimate LSSystem is not CARB(California Air ResourcesBoard) approved for useon emission controlledvehicles. This system isdesigned to control theEFI and ignition on LSbased engines beingretrofit into older vehi-cles that do not requireemission controls (pre-1976).Dimensions and Hood Clearance Intake manifold is " tall as measured from the top surface of the block.

4 The throttle body will clear any stock truck accessories depending on the type of water pump, if there istruck water pump accessory clearance interference you will need to get a new LS1 water pump and acces-sory bracket. The throttle body sits at at a downward angle of 7 degrees. Before installing your FiTech Intake manifold it is recommended to check hood clearance. This can be donein a few simple steps as follows: First, using modeling clay or putty, (not included), make several small cones about 2-3 inches high.

5 Position the cones on the the various areas where you think clearance might be tight. Close the hood to locked position and re-open. The height of the cone indicates the space be-tween the hood and the air cleaner. Record these measurements. We recommend 1" of clearance. Modification of the hood might be necessary to ensure there is no damage to any Status1 Dimensions & Hood Clearance1 Parts Required Not Included1 Kit Contents 500 HP2 Kit Contents 750 HP2 Modified Engines3 Features3 Engine Protection Features3 Special Instructions3 Installing the Manifold4 Installing the Throttle Body5 Installing the Fuel Rails5 Wiring Systems6 Wiring Diagram6 VSS7 Main Power7 Accessory Wires7 Wiring Diagram (Continued)

9 The intakemanifold will have the best fitment when the engine block and cylin-der heads are machined to standard OE dimensions. If the engineblock or cylinder head deck surfaces have been milled significantly,the alignment of the mounting bolt holes and the port flange open-ings to the cylinder head may be shifted and not match up satisfac-torily. If your engine has had the cylinder heads or engine block decksurfaces milled, the following may be necessary for proper intakemanifold installation. The bolt holes in the intake manifold wouldhave to be slotted to allow the fastener to properly pass through themanifold mounting holes.

10 The mounting fasteners must freely threadinto the cylinder head while passing through the mounting holes oroverture .. thethe manifold may not seat properly onto the cylinder head surfaceswhen the fasteners are tightened. As the o-ring grooves are locatedin the intake manifold mounting flanges, material may not be re-moved from the intake manifold mounting flanges without jeopard-izing the sealing of the manifold. Any material removal required toalign the port flange openings should be removed from the cylinderhead not the intake manifold.
