Approval does not signify that the contents necessarily reflect the views and policles 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 for installation on 1992 and older General Motors (GM) vehicles equipped with 262 CID (4.2L) to 400 CID (6.6L) V~8 gasoline engines. Crane Cams has submitted a completed application and all the required information, as well as exhaust emission test data performed at Crane Em;ssions 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 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—3 be issued.

INTRODUCTION Crane Cams, Inc. of 530 Fentress Blvd., Daytona Beach, Florida 32114, bas applied for an exemption from the prohibitions of Vehicle Code Section 27156 on their Fireball cylinder head for installation on 1992 and older General Motors vehicles. Crane Cams has submitted a completed application and all the required information, as Qell as exhaust emission test data performed at Crane Emissions Laboratory which show that the Fireball cylinder head does not have any adverse effects on the exhaust emission for those affected vehicles. 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 will not adversely affect exhaust emission on those vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Crane Cams, Inc. be granted an exemption as requested and that Executive Order D—225~3 be issued. * IV. FIREBALL CYLINDER HEAD DESCRIPTION The Fireball cylinder head is specifically designed for installation on 1992 and older General Motors vehicles powered by 262 CID (4.2L) to 400 CID (6.6L) V—8 gasoline engines. ‘The Fireball cylinder head operates in conjunction with the original equipment manufacturer‘s (OEM) emission ~1—

control systems already certified with the stock engine. The purpose of using the modified Fireball cylinder head is to increase the overall engine performance and reliability 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 sealin§ 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 specifications: 1. Head Casting ———————— Cast Iron 2. Valveg —————_—_———___~ 2.02" Diameter Intake (Stainless Steel) ______________ 1.6" Diameter Exhaust (Stainless Steel) 3. Chamber Volume —————— 67 ce 4. Spark Plug —————————~ Angled 5. Valve Seals ————————~— Nitrile 6. Valve Locks ——~~————— Chrome—Moly & Retainers 7. Valve Springs ——————— Dual Chrome—Silicon v. DISCUSSITON OF THE FIREBALL CYLINDER HEAD Crane Cams submitted emission testing conducted at Crane Emissions Laboratory. A 1984 federally—certified Chevrolet Camaro powered by a 305 CID engine was used as the test vehicle for the Fireball cylinder head. To calibrate the Camaro to California specifications, Crane Cams changed the prom based on documentation given to Crane Cams by General Motors. This —2—

calibration change was verified and accepted by the ARB when Crane Cams was testing for their Compucam 2000 series camshafts on the same GM applications. The dynamometer inertia weight and loading used during the testing were 3625 lbs. and 7.8 hp, respectively. The emission tests consisted of two cold—start CVS—75 Federal Test Procedure in the modified configuration. The test results are shown in Table 1. Table ; cvs—75s TEst RESULTS (Crane Emissions Laboratory) Test Exhaust emission (gm/mi) Modge Ec co Hox Fireball Head Test 1 0.33 5.48 0.66 Fireball Head Test 2 0.26 4.77 0.66 Average of Test 1 & 2 °.295 C 5.13 O.66 Standard 0.39 7.0 0.7 The CVS—75 emission tegt results at Crane Emissions Laboratory indicate that HC, CO and NOx emission of the Fireball cylinder head to be below the emission standard set for that engine family. The ARB did nét conduct confirmatory tests to validate the emission test results submitted by Crane Cams. However, an engineering analysis was performed to determine the Fireball cylinder head‘s effect on the engine‘s valve characteristics, lift and duration. The Fireball cylinder head is functionally identical to the original equipmént manufacturer (OEM) —3—

except for its intake and exhaust valve sizes. A typical GM cylinder head may have intake valves ranging from 1.72 to 1.94 inches and 1.5 to 1.6 inches on exhaust. Crane Cams consolidated these variation by designing their cylinder head to be at the top end of the OEM scale, 2.02 inches on intake and 1.6 inches on exhaust. The exhaust valve diameter is still within acceptable OEM range while the intake valve diameter translates to a 5 percent increase over OEM. This change is insignificant when compared to Crane Cams previously exempted camshafts}which increase valve lift and duration up to 20 percent. Staff‘s analys;s supports Crane Cams‘ test results which show the Fireball cylinder head 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 Fiteball cy1inder head meet the requirements for the exemption.
