Installation Instructions:

1. Make sure the ignition switch is off. Disconnect the battery cables at the battery.
2. Refer to FIG 1: Unplug TPI harness A, injector harness C, remove air temperature sensor B.
3. Refer to FIG 3: Pull throttle actuator arm out of plastic clip F in throttle advance cam. Remove locking nut G and remove throttle advance cam. Set aside for later use.
4. Refer to FIG 2: Remove two bolts D from vapor separator/cover plate. Loosen (12) bolts E from cover plate. Remove all bolts but one. Support plenum box while removing final bolt. Tilt bottom of air box forward so as to remove cover assembly.
5. Remove (6) #10 screws from front of SVS. Remove cover assembly and slide assembly, and set aside.
6. Inspect intake manifold to plenum box gaskets, replace if damaged. Inspect rubber seal on front of plenum box to make sure it is positioned properly. Position SVS base on plenum box, install (2) provided 8mm x 90mm Allen screws in bottom two holes.
7. Align SVS/plenum box with motor intake manifold. So as not to damage gasket, start one of the 8mm screws. Install remaining screws, hand tighten. Torque screws to 19-inch pounds, working from the center outward.
8. Secure vapor separator to SVS with bolts removed earlier, torque to 45-inch pounds.
9. Reconnect TPI and injector harness and replace air temperature sensor with (3) screws previously removed.
10. Refer to FIG 4: Insert slide assembly into SVS base. Be sure to correctly insert brass bushing H of slide assembly into elongated slot in linkage.
11. Install SVS cover plate assembly with (6) provided #10 screws and lock washers using loctite, torque to 25-inch pounds.
12. Refer to FIG 5: Liberally apply grease to throttle pivot shaft I. Install provided spring J to screw on base linkage, and screw on throttle cam linkage assembly K. Stretch linkage assembly onto throttle pivot shaft I, aligning slot over bushing, FIG 6 N. Secure with lock nut removed earlier. Tighten lock nut to make full contact, then back off 1/4 turn.
13. Refer to FIG 3: Locate original throttle advance cam F previously removed, remove plastic swivel by pushing a 5/16 socket over the back of the swivel. Push plastic swivel into the new SVS advance cam, FIG 6 L. Install steel throttle linkage into plastic swivel L.
14. Reconnect battery, look over entire installation making sure no chafing of wires or cables will occur. Install flywheel cover, refer to linkage adjustments.

Linkage Adjustments:

The following linkage adjustments are to ensure that the original butterflies operate as originally designed, opening and closing fully, and that the SVS opens fully, at wide-open throttle and returns fully closed. These movements should operate smoothly without binding or having any interference.

1. Refer to FIG 6: Back off stop screws O and P so as not to interfere with travel of linkage assembly. Align marks on roller M with mark on throttle advance cam. Check for .005-.010 inch clearance between roller and cam. If necessary, adjust by loosening cam follower screw and moving roller to position, then tighten screw.
2. With throttle in idle position, adjust screw P to achieve .010 inch clearance with throttle advance cam. Tighten locking nut to prevent movement.
3. Have an assistant operate throttle to wide-open position. IMPORTANT: Original butterflies MUST be wide open, if necessary, to adjust wide-open throttle position. Refer to FIG 7: Loosen lock nut and adjust screw Q, tighten lock nut. Operate throttle several times to ensure wide-open throttle.
4. Refer to FIG 6: With throttle in wide-open position, adjust stop screw O to achieve wide-open throttle of SVS. Operate throttle several times to ensure wide-open throttle. Tighten locking nut on screw O to prevent movement.
