     J. Bittle American, Inc.   (JBA) has applied for an exemption from the

prohibitions of Vehicle Code Section 27156 for their 1.7 Roller Rocker, part

nos. 2341, 2343, 2321, and 2331 for installagion on 1992 and older Ford

Motor Company vehicles equipped with 289 to 351 CID V—8 gasoline engines.

JBA has submitted a completed application and all the required information,

as well as exhaust emissions test data performed at Crane Emissions

Laboratory which demonstrated that the specified 1.7 Roller Rocker does not

have any adverse effect on the exhaust emissions of the affected vehicles.

     Based on the submitted informatign and results of the emission tests

performed at Crane Emissions Laboratory, the staff concludes that the

installation of JBA‘s 1.7 Roller Rocker will not adversely affect exhaust

emissions on the specified vehicles.

     The staff recommends J. Bittle American,   Inc. be granted an exemption

as requested and that Executive Order D—216—7 be issued.

I.    INTRODUCTION                                                     «

      J. Bittle American, Inc.    (JBA) of 9630 Aero Dr., San Diego, California

92123, has applied for an exemption from the prohibitions of Vehicle Code

Section 27156 for their 1.7 Roller Rocker,     part nos.   2341,   2343,   2321,   and

2331 for installation on 1992 and older Ford Motor Company vehicles.               JBA

has submitted a completed application and all the required information, as

well as exhaust emissions test data performed at Crane Emissions Laboratory.

II.    CONCLUSIONS                      ‘

      Based on the submitted information and results of the emission tests

performed at Crane Emissions Laboratory, the staff concludes that the J.

Bittle American,     Inc. 1.7 Roller Rocker will not adversely affect exhaust

efiisaions from vehicles for which the exemption is requested.

III. RECOMMENDATION
      The staff recommends that J.   Bittle American,   Inc.   be granted an

exemption as requested and that Executive Order D—216—7 be issued.

IV.   1.7 ROLLER ROCKER DESCRIP:ION(

      The JBA 1.7 Roller Rocker is designed to increase the rocker arm ratio

of the small block Ford V—8 gasoline engines with 289 to 351 CID engine

sizes from a 1.6:1 to 1.7:1.     The 1.7 Roller Rocker operates in conjunction

with the original equipment manufacturer‘s (OEM) emission control systems

already certified with the stock engines.     The purpose of using the modified

1.7 Roller Rocker is to increase the overall engine performance by modifying

the valve characteristics.


v.   BISCUSSION OF THE 1.7 ROLLER ROCKER

     JBA submitted emission testing conducted at Crane Emissions Laboratory.

A 1991 Ford Mustang powered by a 302 CID engine was used as the test vehicle

for the 1.7 Roller Rocker.     The dynamometer inertia weight and loading used

during the testing were 3625 lbs. and 7.7 hp; respectiyely.

     Emissions testing consisted of one cold—start CVS—75 Federal Test

Procedure in the modified configurations evaluated against the vehicle‘s

emission standards.     The test results are shown in Table 1.




                                      Table 1




                              CVs—75 TEST RESULTS

                           (Crane Emissions Laboratory)



             Test                      Exhaust Emissions (gm/mi)

            Mode                       BC       co      NOx

             Standard                 0.41      3.4     1.0

             1.7 Roller Rocker    |    0.19      1.95   0.41



             Difference               ~0.22     —1.45 —0.59




     The CVS—75 emissions test results at Crane Emissions Laboratory

indicate that HC, CO and NOx emissions of the 1.7 Roller Rocker are below

the emission standards for that vehicle.        The test results do demonstrate

that the installation of the 1.7 Roller Rocker for all 1992 and older Ford

Motor Company vehicles powered by a 289 to 351 CID V—8 gasoline engines will

                                        —2—


not adversely affect the exhaust emissions.   Results were not confirmed by

the ARB; however, the test results are consistent with previous testing

conducted on similar rocker arms with increased ratio of 1.7.

     JBA has submitted all the required information and fulfilled the

requirements for an exemption.   The test resuits and engineering evaluation

confirmed that JBA 1.7 Roller Rocker, part nos. 2341, 2343, 2321,   and 2331

meet the requirements for the exemption.
