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)

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.

       Fireball Head Test 1                0.21    2.45   0.57

       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.
