                          EXECUTIVE ORDER D—333—3
                 Relating to Exemptions Under Section 27156
                            of the Vehicle Code

                 LINGENFELTER PERFORMANCE ENGINEERING, INC.
                   LINGENFELTER 350 CID LT—5 ZR—1 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 LT—5 ZR1 Engine, manufactured by Lingenfelter Performance Engineering,
Inc. (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 LT—5 ZR—1
Engine is exempt from the prohibitions of Section 27156 of the Vehicle Code
for 1990—1995 model—year Chevrolet Corvettes equ1pped with 5.7 L LT—5 ZR—1
gasoline engines.

The Lingenfelter 350 CID LT—5 ZR—1 Engine uses new pistons, connecting rods,
after catalyst exhaust system, and re—worked cylinder heads, intake
manifold, intake runners, and PROM chip.
This Executive Order (Order) is valid provided that installation of the
Lingenfelter 350 CID LT—5 ZR—1 Engine 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 Lingenfeiter 350
CID LT—5 ZR—1 Engine, as exempt by the ARB, which may adversely affect the
performance of a vehicle‘s poliution control system shall invalidate this
Executive Order.

Marketing of the Lingenfelter 350 CID LT—5 ZR—1 Engine using an
identification other than that shown in this Executive Order or marketing of
the Lingenfelter 350 CID LT—5 ZR—1 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 LT—5 ZR—1 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, the ARB finds that reasonable grounds exist to believe that use of
the Lingenfelter 350 CID LT—5 ZIR—1 Engine may adversely affect emissions of

motor vehicles when operating under conditions outsidse the paramstsrs 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 LT—5 ZR—1
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 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 reasons to suspect that the
Lingenfelter 350 CID LT—5 ZR—1 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 exemption 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, INC.‘S LINGENFELTER 350
CID LT—5 ZR—1 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 Order. The Order may be revoked only after a 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 the
hearing that grounds for revocation exist.
