The CCT Upgrade Kit rebuilds all applicable engines to federal 1991—1993 model—year DDC specification. The CCT Upgrade Kit is exempt only when used in conjunction with other DDC engine rebuild parts. The required CCT Upgrade Kit parts and DDC rebuild parts are listed in the parts lists which are attached hereto and incorporated herein. The CCT Upgrade Kit includes patented engine camshafts, CCT cylinder kits, CEM II catalytic mutffler, and 0.015 offset key to retard fuel injection timing. For 1985—1987 model—year engines, the CCT Upgrade Kit also includes DDEC I to DDEC II conversions parts, fuel injectors, turbocharger, blower assembly, blower bypass valve, 40—tooth blower drive gear, and an ECM upgrade. For 1988—1990 model—year engines, the CCT Upgrade Kit also includes fuel injectors and an ECM upgrade. For 1985—1990 model—year engines, DDC‘s revised certification word codes listed in Attachment A must be used. For 1991—1993 model—year engines, the revised certification word codes may be used. This exemption is based on emission tests conducted by Johnson Matthey, Inc. on a 1992 model—year 6GV9ZTA DDEC II engine rebuilt to a federal 1991 model—year urban bus engine configuration. Johnson Matthey, Inc. submitted the following federal transient heavy—duty diesel engine test results for a 552 cubic inch G6V92TA DDEC engine with a 277 horsepower rating:
