                                  SUMMARY


     Crane Cams, Inc. has applied for an exemption from the prohibitions of

the Vehicle Code Section 27156 for their Compucam 2000 series 2010, 2020,

and 2030 camshafts for installation on 1987 and older General Motors
vehicles equipped with 267 CID (4.4L) to 350 CID (5.7L) V—8 gasoline engines

utilizing feedback or conventional carburetors.   Crane Cams 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 camshafts do not have any adverse effect on

the exhaust emissions of the affected vehicles.   Testing performed at the

Air Resources Board (ARB) confirmed the test results of Crane Emissions

Laboratory.

     Based on the submitted information and the results of the emissions

tests performed at Crane Emissions Laboratory and the ARB, the staff

concludes that the installation of Crane Cams‘ Compucam 2000 series will not

adversely affect exhaust emissions on the specified vehicles.

     The staff recommends Crane Cams, Inc. be granted an exemption as

requested and that Executive Order D—225 be issued.

 EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE
     WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS



I.     INTRODVEGTION
       Crane Cams, Inc. of 530 Fentress Bivd., Daytona Beach, Florida 32114,

has applied for an exemption from the prohibitions of Vehicle Code Section

27156 for their Compucam 2000 series 2010, 2020, and 2030 camshafts for

installation on 1987 and older General Motors vehicles using feedback or

conventional carburetors.

       Crane Cams 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 Compucam 2000 series does

not have any adverse effect on the exhaust emissions of the affected

vehicles.    Testing performed at the Air Resources Board (ARB) confirmed the

test results of Crane Emissions Laboratory.

       The staff recommends Crane Cams, Inc. be granted an exemption as

requested and that Executive Order D—225 be issued.

I1I.   CONCLUSIONS
       Based on the submitted information and the results of the emissions
tests performed at Crane Emissions Laboratory and confirmatory

testing conducted at the ARB, the staff concludes that the Crane Cams, Inc.

Compucam 2000 series will not adversely affect exhaust emissions from

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 be issued.

 IV.   COMPUCAM2000SERIESDESCRIPTION
       Compucam 2010, 2020, and 2030 are specifically designed for

‘installation on 1987 and older General Motors vehicles powered by 267 CID

 (4.4L) to 350 CID (5.7L) ¥—8 gasoline engines.       The camshafts operate in

 conjunction with the original equipment manufacturer (OEM) computer

 controlled feedback or conventional carburetors along with the emission

 control systems already certified with the stock engines.       The purpose of

 using the Compucam 2000 series camshafts is to increase the overall engine

 performance by modifying the valve characteristics, such as increasing

 the valve lift and duration.

       The three camshafts vary in their characteristics, ranging from

 moderate to high engine performance.     The cam lobes on the Compucam 2010

 have been increased by 7.5 percent on the intake and 4.2 percent on the

 exhaust when compared to the OEM camshaft.        These increases translate to a

 mild increase in valve lift, allowing the engine to increase its volumetric

 efficiency.   The Compucam 2020 is designed to provide a mid—range

 performance with a 13.9 percent increase on the intake lobe and a 10.2

 percent increase in the exhaust lobe.        The greatest increase in cam lobe

 lift is on the Compucam 2030 which has a 20.3 percent increase in the intake

 lobe and a 16 percent increase in the exhaust lobe.        The Compucam 2010 works

 best on the 267 CID engine while the Compucam 2030 is designed to enhance

 the performance of the high output 350 CID engine.

 V.    DISCUSSIONOFTHECOMPUCAM2000SERIES
       A 1984 Chevrolet Camaro powered by a 305 CID engine was used for the

 evaluation of the Compucam 2000 series camshafts.       Documentation given to

 Crane Cams by General Motors indicated that a prom change would calibrate

 their Camaro to California specifications.       This information was verified by

                                        «2—


the ARB during the application process and confirmatory testing.          The

dynamometer inertia weight and loading used during the testing were 3625

lbs. and 7.8 hp, respectively.

     Emission tests conducted by Crane Emissions Laboratory consisted of

cold—start CYS—75 emission tests with the Compucam 2030 installed on the

test vehicle, and the vehicle calibrated to California configuration.           This

test was used to compare vehicle exhaust emissions in the modified

configuration with the applicable emission standards.           The test results are

shown in Table 1.

              Average Compucam        0. 32     4.29   0.46



     Confirmatory testing was performed at the ARB.           The results are shown

in Table 2.

                                      HC      CQ     NQx
             Compucam 2030 test 1    0.36     5.84   0.49

            Average Compucam         0.37     6.32   0.49



     The CVYS—75 emissions test results at Crane Emissions Laboratory and

confirmatory testing at the ARB indicate that HC, CO and NOx emissions of

the Compucam 2030 camshaft are well below the emission standards.   This

demonstrates that the installation of the Compucam 2000 series camshafts

will not adversely affect the exhaust emissions of 1987 and older General

Motors vehicles powered by 267 CID (4.4L) to 350 CID (5.7) V—8 gasoline

engines.

     Crane Cams has submitted all the required information and fulfilled the

requirements for an exemption.   The test results confirmed that Crane Cams‘

Compucam 2000 series meets the requirements for the exemption.
