                                   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.

 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)

              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 ;

                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.
