camshafts are specifically designed for installation on 1987 and older

General Motors vehicles equipped with a 267 to 350 CID carbureted engine.

The camshafts operate in conjunction with the original equipment

manufacturer‘s (OEM) emissions control system already certified with stock

engine.     The purpose of using the Pure Energy camshaft is to increase the

overall engine performance which is a direct result of modifying valve.

characteristics.       An example would be an increase in valve lift and

duration.
        The specifications of the Pure Energy camshafts are tabulated in Table

1.

¥.      DISCUSSION OF THE CAMSHAFT

        A 1987 Chevrolet Camaro powered by a 305 CID engine was used for the

evaluation of the Pure Energy camshafts, part nos. 12—207—2, 12—208—2, 12—

206—2, 12—314—4, 12—310—4, 12—312—4, 12—402—4, 12—106—3, 12—400—4, and 12—

210—2 camshafts.       The dynamometer inertia weight and loading used during the

testing were 3625 lbs. and 7.6 hp, respectively.
                                                —2—


     Emission tests conducted by Roush Laboratories consisted of one cold—

start CVS—75 emission test.     The Pure Energy camshaft, part no. 12—106—3 was

installed on the test vehicle with emission results compared to the

vehicle‘s emission standards.     The test results are shown in Table 2.

                              CVS—75 TEST RESULTS

                                       HC      c0     NOx
             Standard                 0.39     7.0    0.7

           — Device                   0.38     2.87   0.25


     These resu]fs show that the modified vehicle emissions do not exceed
the véh%é]e’s emfssion standards.     Staff did not perfb}m confiffiétory

testifié to validate test data submitted by Competitioh Cams.

     Competition Cams has submitted all the required information and
fulfilled the requirements for an exemption.
