1. PREPARATION/REMOVAL A. B. C. D. E. 2. Disconnect the negative lead to the battery. Remove the fan and shroud to aid in installation. It may also be necessary to install a fan spacer at a later time. (V-Belt) Loosen all nuts and bolts that are used to tension the alternator and power steering pump V-belts. Remove the factory belts. (Serpentine) Loosen tension on the tensioner and remove the factory drive belt.
3. OIL DRAIN INSTALLATION A. To provide an oil drain for the supercharger, it is necessary to make a hole in the oil pan. Locate and mark the hole location. (See Fig. 3-a.) It is best to punch the hole rather than drill. NOTE: B. C. D. Remove any paint from around the hole area. Use a small center punch to perforate the pan and expand the hole, switch to a larger diameter punch and expand the hole further to approximately Ø9/16".
4.1 MAIN BRACKET/SUPERCHARGER INSTALLATION (Serpentine) NOTE: A. B. C. D. E. Some applications (depending on intake manifold height) may require the reclocking of the supercharger volute. If reclocking is required for your application, loosen and remove the six 1/4-20 cap screws and retaining plates that hold the compressor housing (volute) to the gearcase. If the compressor housing does not rotate freely relative to the gearcase, DO NOT FORCE IT. SERIOUS SUPERCHARGER DAMAGE MAY OCCUR.
4.1 F. G. MAIN BRACKET/SUPERCHARGER INSTALLATION (Serpentine), cont’d Attach the oil drain hose to the 1/2" barbed fitting on the bottom of the supercharger. Secure the hose with the supplied hose clamp. Using the supplied 3/8-16 x 1.25" screws secure the supercharger to the mounting plate. (See Fig. 4.1-b.) Fig. 4.1-c 4.2 A. MAIN BRACKET/SUPERCHARGER INSTALLATION (V-Belt) Locate the supplied cast bracket. (See Fig. 4.2-a.) NOTE: B. C.
2. 3. Mount the power steering pump to the back side of the cast bracket using the supplied 3/8-16 flat-head screws. Locate the power steering pump drive flange. Using the appropriate GM power steering pulley installer, install the drive flange as you would a normal power steering pulley. (See Fig. 4.2-b.) Using the six 1/4-20 x .75" screws and washers, attach the supplied power steering pulley. (Blue loc-tite on the threads is recommended.) (See Figs. 4.2-b, 4.2-c.) NOTE: D. E. F.
5. CRANK PULLEY AND SUPERCHARGER DRIVE PULLEY INSTALLATION NOTE: Two crank pulley spacers are provided in this system. 4GP017-031 (3.695" long) is to be used for serpentine drive systems. The 4GP017-041 (3.293" long) is to be used for V-belt applications. A. B. Locate the supercharger drive assembly (4GP116-041). Using the 7/16-20 x 6" screw and washer, loosely install the appropriate spacer for your application to the front of the factory crank pulley.

6. DISCHARGE DUCTING/CARBURETOR ENCLOSURE NOTE: 1. 2. 3. 4. A. B. C. OPTIONAL: Due to the many possible configurations of intake manifolds (with regard to carburetor flange height) a carburetor spacer may be required to obtain the necessary height for proper supercharger and discharge duct alignment. As an option, the carburetor enclosure cover may be turned around so that the inlet is facing the passenger side of the vehicle.
7. FINAL REASSEMBLY AND CHECK WARNING: Do not attempt to operate the vehicle until all components are installed and all operations are completed including final check. A. B. C. D. E. F. G. H. I. J. K. Refit the upper fan shroud. Reconnect the battery. If your vehicle has gone over 15,000 miles since its last spark plug change, you will need to change the spark plugs now before test driving the vehicle. Check all fittings, nuts, bolts and clamps for tightness.
