                              State of California
                              AIR RESOURCES BOARD

                           EXECUTIVE ORDER D—333—2
                 Relating to Exemptions Under Section 27156
                              of the Vehicle Code
                LINGENFELTER PERFORMANCE ENGINEERING, INC.‘S
                LINGENFELTER 350 CID LT—5 ZR1 ENGINE PACKAGE
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—5;

IT IS ORDERED AND RESOLVED:   That the installation of the Lingenfelter 350
CID LT—5 ZR1 Engine Package manufactured by Lingenfelter Performance
Engineering, Inc. {Lingenfelter) of 1557 Winchester Road, Decatur, Indiana
4§733, has been found not to reduce the effectiveness of the applicable
vehicle polliution control system and, therefore, is exempt from the
prohibitions of Section 27156 of the Vehicle Code for 1990—1994 model year
Corvettes equipped with a 5.7L LT—5 ZR1 gasoline engine.

The Lingenfelter 350 CID LT—5 ZRl Engine Package uses new pistons,
connecting rods, after catalyst exhaust system, and reworked cylinder heads,
intake manifold, intake runners, and PROM chip.

This Executive Order is valid provided that the installation of the
Lingenfelter 350 CID LT—5 ZR1 Engine Package is conducted by Lingenfelter
and no changes are made to the stock tune—up specifications.
Changes made to the design or operating conditions of the Lingenfelter 350
CID LT—5 ZR1 Engine Package, 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 LT—5 ZRl Engine Package using any
identification other than that shown in this Executive Order or marketing of
the Lingenfelter 350 CID LT—5 ZR1l Engine Package 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 LT—5 ZRl Engine Package may have on any warranty either
expressed or implied by the vehicle manufacturer.

This Executive Order is granted based on results from emissions tests
conducted in accordance with Cold—Start CVS—75 Federal Test Procedure.
However, the ARB finds that reasonable grounds exist to believe that use of
the Lingenfelter 350 CID LT—5 ZR1 Engine Package may adversely affect
emissions of motor vehicles when operating under conditions outside the
parameters of the previously prescribed test procedures.     Accordingly, the


Lingenfelter             .                        EXECUTIVE ORDER D—333—2
                                                  (Page 2 of 2)


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 LT—5 ZR1 Engine Packages adversely affect emissions
during off—cycle conditions (defined as those conditions which are beyond
the parameters of the Cold—Start CVS—75 Federal Test Procedure), this
Executive Order shall be effectively rescinded as of the date the test
results are validated. Further, if such test results or other evidence
provides the ARB with reason to suspect that the Lingenfelter 350 CID LT—5
ZR1 Engine Packages will affect the durability of the emission control
system, Lingenfelter shall be required to submit durability data to show
that the durability of the vehicle emission control system is not, in fact,
gffeg§$qtand/or that the add—on or modified part demonstrates adequate
 urability.      —

In addition to the foregoing, the ARB reserves the right in the future to
review this Executive Order and the exemption provided herein to assure that
the exempted add—on or modified part continues to meet the standards and
procedures ofTitle 13, California Code of Regulations, 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, INC.‘S LINGENFELTER 350
CID LT—5 ZRl ENGINE PACKAGE.
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 order. The order may be revoked only after ten day written notice of
intention to revoke the order, in which period the holder of the 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 order may not be revoked until a determination after hearing
that grounds for revocation exist.

Executed at E1 Monte, California, this   /foaéay of May, 1994.
