                           EXECUTIVE ORDER D—~333—18
                   Relating to Exemptions Under Section 27156
                              of the Vehicle Code

                     LINGENFELTER PERFORMANCE ENGINEERING
                         LINGENFELTER 350 CID ENGINE


Pursuant to the authority vested in the Air Resources Board (ARB) by Section
27156 of the Vehicle Code; and

Pursuant to the authority vested in the undersigned by Sections 39515 and
39516 of the Health and Safety Code and Executive Order G—45—~9;

IT IS ORDERED AND RESOLVED:  That the installation of the Lingenfelter 350 CID
Engine, manufactured by Lingenfelter Performance Engineering (Lingenfelter) of
1557 Winchester Road, Decatur, Indiana 46733, has been found not to reduce the
effectiveness of the applicable vehicle pollution control system, and
therefore, the Lingenfelter 350 CID Engine is exempt from the prohibitions of
Section 27156 of the Vehicle Code for 1997 model—year General Motors
Corporation Corvettes equipped with 5.7 L LT—1 and LT—4 gasoline engines.

The Lingenfelter 350 CID Engine uses new camshaft, double valve springs,
titanium valve spring retainers, K/N replacement air filter (part no.
33—2014), and after catalyst exhaust system and re—worked cylinder heads and
intake manifold.

This Executive Order is valid provided that installation of the Lingenfelter
350 CID Engine is conducted by Lingenfelter and no changes are made to the
vehicle manufacturer tune—up specifications.

Changes made to the design or operating conditions of the Lingenfelter 350 CID
Engine, as exempt by the ARB, which may adversely affect the performance of a
vehicle‘s pollution control system shall invalidate this Executive Order.

Marketing of the Lingenfelter 350 CID Engine using an identification other
than that shown in this Executive Order or marketing of the Lingenfelter 350
CID Engine for an application other than those listed in this Executive Order
shall be prohibited unless prior approval is obtained from the ARB.

This Executive Order does not constitute any opinion as to the effect the
Lingenfelter 350 CID Engine may have on any warranty either expressed or
implied by the vehicle manufacturer.

This Executive Order is granted based on the results from previous emission
tests conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
However, ARB finds that reasonable grounds exist to believe that use of the
Lingenfelter 350 CID Engine may adversely affect emissions of motor vehicles
when operating under conditions outside the parameters of the previously
prescribed test procedure.  Accordingly, the ARB reserves the right to conduct
additional emission tests in the future,   as such tests are developed,   that
will more adequately measure emissions from all cycle phases.

If such test results demonstrate that the Lingenfelter 350 CID Engine
adversely affects emissions during off—cycle conditions (defined as those
conditions which are beyond the parameters of the Cold—Start CVS—75 Federal
Test Procedure), this EBxecutive Order shall be effectively rescinded as of the
date the test results are validated.   Further, if such test results or other


LINGENFELTER                                               EXECUTIVE ORDER D~333—18
LINGENFELTER 350 CID ENGINE                                (Page 2 of 2)


evidence provides the ARB with reasons to suspect that the Lingenfelter 350
CID Engine will affect the durability of the emission control system,
Lingenfelter shall be required to submit durability test data to show that the
durability of the vehicle emission control system is not, in fact, affected
and/or that the add—on or modified part demonstrates adequate durability.

In addition to the foregoing, the ARB reserves the right in the future to
review this Executive Order and the exemptions provided herein to assure that
the exempted add—on or modified part continues to meet the standards and
procedures of California Code of Requlations, Title 13, Section 2222 et seq.

THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION,
APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT BY THE AIR RESOURCES BOARD OF
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF LINGENFELTER PERFORMANCE ENGINEERING‘S LINGENFELTER 350 CID
ENGINE.

No claim of any kind, such as "Approved by the Air Resources Board," may be
made with respect to the action taken herein in any advertising or other oral
or written communication.

Violation of any of the above conditions shall be grounds for revocation of
this Executive Order.   The Executive Order may be revoked only after a ten—day
written notice of intention to revoke the Order,      in which period the holder of
the Executive Order may request in writing a hearing to contest the proposed
revocation.  If a hearing is requested, it shall be held within ten days of
receipt of the request and the Executive Order may not be revoked until a
determination after the hearing that grounds fpr revocation exist.

Executed at El Monte, California, this   <2 2   day
