                              EXECUTIVE ORDER D—333—10
                     Relating to Exemptiong Under Section 27156
                                 of the Vehicle Code

                          LINGENFELTER 350 CID LT—l1 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~1 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 LT—1 Engine is exempt
from the prohibitions of Section 27156 of the Vehicle Code for the following
vehicles equipped with 5.7 L LT—l gasoline engines:

       1.       1992—1996 Chevrolet Corvettes
       2.       1993—1996 Chevrolet Camaros
       3.       1993—1996 Pontiac Firebirds and Trans Ams
       4.       1994—1996 Chevrolet Impala SS, Caprice, and
                other General Motors Corporation B—body vehicles

The Lingenfelter 350 CID LT—l Engine uses new fuel       injéctors,   camshaft,   after
.catalyst exhaust system, and re—worked cylinder heads,       intake manifold,      intake
runners, and PROM chip.

This Executive Order is valid provided that installation of the Lingenfelter
350 CID LT—l 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 LT—1 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 LT—1 Engine using an identification
other than that shown in this Executive Order or marketing of the
Lingenfelter 350 CID LT—1lEngine 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 congtitute any opinion as to the effect the
Lingenfelter 350 CID LT—l 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—l 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

LINGENFELTER                                             EXECUTIVE ORDER D—333—10
LINGENFELTER 350 CID LT—l ENGINE                         (Page 2 of 2)

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—l 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 provide the ARB with reasons to suspect that the Lingenfelter
350 CID LT—l1 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 modifi¢ed 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 Regulations, Title 13, Section 2222 et seq.


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 reéevoke the Executive 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 for revocation exist.

Executed at El Monte, California, this ;;;3   day
