State of California AIR RESOURCES BOARD EVALUATION OF CRANE CAMS, INC. FIREBALL CYLINDER HEAD FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS by Mobile Source Division State of California Air Resources Board 9528 Telstar Avenue El Monte, CA 91731—2990 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approval does not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does the mention of trade names or commercial products constitute endorsement or recommendation for use.)

SUMMARY Crane Cams, Inc. has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their Fireball cylinder head (P/N 36900—1) for installation on 1992 and older Ford vehicles equipped with 221 to 351 CID V—8 gasoline engifies. Crane Cams has submitted a completed application and all the required information, as well as exhaust émission test data performed at Crane Emissions Laboratory which demonstrated that the specified Fireball cylinder head does not have any adverse effects on the exhaust emission of the affected vehicles. Based on the submitted information, results of the emission tests performed at Crane Emissions Laboratory, and an engineering evaluation, the staff concludes that the installation of Crane Cams‘ Fireball cylinder head (P/N 36900—1) will not adversely affect exhaust emission on the specified vehicles. The staff recommends Crane Cams, Inc. be granted an exemption as requested and that Executive Order D—225—4 be issued.

II. CONCLUSION Based on the submitted information, results of the emission tests performed at Crane Emissions Laboratory, and an engineering evaluation, the staff concludes that the Crane Cams‘ Fireball cylinder head (P/N 36900—1) will not adversely affect exhaust emission on those vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Crane Camse, Inc. be granted an exemption as requested and that Executive Order D~225—4 be issued. IV. FIREBALL CYLINDER HEAD DESCRIPTION The Fireball cylinder head (P/N 36900—1) is specifically designed for installation on 1992 and older Ford vehicles equipped with 221 to 351 CID V—8 gasoline engines. The Fireball cylinder head operates in conjunction with the original equipment manufacturer‘s (OEM) emission control systems —1—

already certified with the stock engine. The purpose of using the modified Fireball cylinder head (P/N 36900—1) is to increase the overall engine performance and reliabllity which is accomplished according to the manufacturer, through labor intensive machining and the use of the finest materials available. The intake and exhaust ports are machined to match the gasket and manifold surfaces, thus eliminating reversion at those junctures. The interior surfaces of the ports have been machined in the critical areas to reduce backpressure and maintain laminar flow. The valve seats are machined to provided optimum sealing and increase flow. The combustion chambers are polished to eliminate hot spots which could cause detonation or pre—ignition. The following are the Fireball cylinder head (P/N 36900—1) specifications: 1. Head Casting ———————— Cast Iron 2. Valves ————~———~——<—~—— 2.02" Diameter Intake (Stainless Steel} —————————————— 1.6" Diameter Exhaust (Stainless Steel) 3. Chamber Volume —————— 69 ce 4. Spark Plug ——~——————— Angled 5. Valve Seals ————————— Nitrile 6. Valve Locoks ————————— Chrome—Moly & Retainers 7. Valve Springs ——————— Dual Chrome—Silicon v. DISCUSSITON OF THE FIREBALL CYLINDER HEAD (P/N 36900—1) Crane Cams submitted emission testing conducted at Crane Emissions Laboratory. A 1991 Ford Mustang (AB 965) powered by a 5.0 liter (302 CID) engine was used as the test vehicle for the Fireball cylinder head (P/N 36900—1)}. The dynamometer inertia weight and loading used during the

testing were 3625 lbs. and 7.7 hp, respectively. The emission tests consisted of one cold—start CVS—75 Federal Test Procedure in the OEM configuration followed by two cold—start CVS—75 Federal Test Procedures in the modified confiquration. The test results are shown. in Table 1. Table 1 CVs—75 TEST RESULTS {Crane Emissions Laboratory) Test Exhaust emission (gm/mi) Mode BC co NOx Standard O.41 3.4 1.0 Fireball Head Test 1 0.21 2.45 0.57 Fireball Head Test 2 0.20 2.20 0.55 Deterioration Factors (DF) 1.243 1.00 1.00 Average with DF ° o.254 2.33 0O.56 The CVS—75 emission test results at Crane Emissions Laboratory indicate the HC, CO and NOx emissions of the 1991 Ford Mustang with the Fireball cylinder head (P/N 36900—1) are below the emission standards. The Air Resources Board did not conduct confirmatory tests to validate the emission test results submitted by Crane Cams. The Fireball cylinder head (P/N 36900—1) is functionally identical to the original equipment manufacturer (OEM) except for its intake and exhaust valve sizes. A typical Ford cylinder head may have intake valves ranging from 1.59 to 1.85 inches and 1.39 to 1.54 inches on exhaust. Crane Cams consolidated these variation —3—

by designing their cylinder head to be at the top end of the scale, 2.02 inches on intake and 1.6 inches on exhaust. This translates to a 4 percent increase in exhaust and an 9.2 percent increase in intake when valve diameters are compared to OEM top scale. These changes are insignificant when compared to Crane Cams previously exempted camshaft, Compucafi 2021, which increased valve lift and duration by 13 percent. Staff‘s analysis supports Crane Came‘ test results which show the Fireball cylinder head (P/N 36900—1)} to have no adverse effect on exhaust emissions of the affected vehicles. Crane Cams has submitted all the required information and fulfilled the requirements for an exemption. The test results and engineering evaluation confirmed that Crane Cams Fireball cylinder head (P/N 36900—1) meets the requirements for the exemption.
