                         12 1/4% Senior Notes due 2007

[INSERT THE GLOBAL NOTE LEGEND, IF APPLICABLE PURSUANT TO THE PROVISIONS OF THE
INDENTURE]

         FOR PURPOSES OF SECTION 1272, 1273 AND 1275 OF THE INTERNAL REVENUE
CODE OF 1986, AS AMENDED, AND THE RULES AND REGULATIONS THEREUNDER, THIS
SECURITY IS BEING ISSUED WITH ORIGINAL ISSUE DISCOUNT; FOR EACH $1,000
PRINCIPAL AMOUNT OF THIS SECURITY, (1) THE ISSUE PRICE IS $963.46; (2) THE
AMOUNT OF THE ORIGINAL ISSUE DISCOUNT IS $36.54; (3) THE ISSUE DATE IS
SEPTEMBER 20, 1999; AND (4) THE YIELD TO MATURITY IS 13.00% (COMPOUNDED
SEMI-ANNUALLY).

         Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

         1.       Interest. Holley Performance Products Inc., a Delaware
corporation (the "Company"), promises to pay interest on the principal amount of
this Note at 12 1/4% per annum from September 20, 1999 until maturity and shall
pay the Special Interest payable pursuant to Section 2(c) of the Registration
Rights Agreement referred to below. The Company will pay interest and Special
Interest semi-annually on March 15 and September 15 of each year, or if any such
day is not a Business Day, on the next succeeding Business Day (each an
"Interest Payment Date"). Interest on the Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from the
date of original issuance; provided that if there is no existing Default in the
payment of interest, and if this Note is authenticated between a record date
referred to on the face hereof and the next succeeding Interest Payment Date,
interest shall accrue from such next succeeding Interest Payment Date; provided,
further, that the first Interest Payment Date shall be March 15, 2000. The
Company shall pay interest (including post-petition interest in any proceeding
under any Bankruptcy Law) on overdue principal and premium, if any, from time to
time on demand to the extent lawful at a rate that is 1% per annum in excess of
the rate then in effect; it shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest
and Special Interest (without regard to any applicable grace periods) from time
to time on demand at the same rate to the extent lawful. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

         2.       Method of Payment. The Company will pay interest on the Notes
(except defaulted interest) and Special Interest to the Persons who are
registered Holders of Notes at the close of business on March 1 or September 1
next preceding the Interest Payment Date, even if such Notes are canceled after
such record date and on or before such Interest Payment Date, except as provided
in Section 2.12 of the Indenture with respect to defaulted interest. Principal,
premium, if any, and interest and Special Interest on the Notes will be payable
at the office or agency of the Company maintained for such purpose or, at the
option of the Company, payment of interest and Special Interest may be made by
check mailed to the Holders of the Notes at their respective addresses set forth
in the register of Holders of Notes; provided that all payments of principal,
premium, interest and Special Interest with respect to Notes the Holders of
which have



   3

given wire transfer instructions to the Company prior to the Record Date will be
required to be made by wire transfer of immediately available funds to the
accounts specified by the Holders thereof. Until otherwise designated by the
Company, the Company's office or agency in New York will be the office of the
Trustee maintained for such purpose. The Notes will be issued in denominations
of $1,000 and integral multiples thereof. Such payment shall be in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.

         3.       Paying Agent and Registrar. Initially, State Street Bank and
Trust Company, the Trustee under the Indenture, will act as Paying Agent and
Registrar. The Company may change any Paying Agent or Registrar without notice
to any Holder. The Company or any of its Subsidiaries may act in any such
capacity.

         4.       Indenture. The Company issued the Notes under an Indenture
dated as of September 20, 1999 ("Indenture") by and among the Company, the
Guarantors and the Trustee. The terms of the Notes include those stated in the
Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939, as amended (15 U.S. Code ss.ss. 77aaa-77bbbb) (the
"TIA"). The Notes are subject to all such terms, and Holders are referred to the
Indenture and such Act for a statement of such terms. To the extent any
provision of this Note conflicts with the express provisions of the Indenture,
the provisions of the Indenture shall govern and be controlling.

         5.       Optional Redemption. Except as set forth in the following
paragraph, the Notes will not be redeemable at the Company's option prior to
September 15, 2003. Thereafter, the Notes will be subject to redemption at any
time at the option of the Company, in whole or in part, upon not less than 30
nor more than 60 days' notice, at the redemption prices (expressed as
percentages of principal amount) set forth below plus accrued and unpaid
interest and Special Interest thereon to but not including the applicable
redemption date, if redeemed during the twelve-month period beginning on
September 15 of the years indicated below:




      YEAR                                                PERCENTAGE
      ----                                                ----------
                                                        
      2003..........................................       106.125%
      2004..........................................       104.083%
      2005..........................................       102.042%
      2006 and thereafter...........................       100.000%


         Notwithstanding the foregoing, at any time prior to September 15, 2002
the Company may on any one or more occasions redeem up to 35% of the aggregate
principal amount of Notes originally issued under the Indenture at a redemption
price of 112.25% of the principal amount thereof, plus accrued and unpaid
interest and Special Interest thereon, if any, to but not including the
redemption date, with the net cash proceeds of one or more Public Equity
Offerings by the Company; provided that (i) at least 65% of the aggregate
principal amount of Notes remain outstanding immediately after the occurrence
of such redemption (excluding Notes held by the Company and its Subsidiaries);
and (ii) such redemption shall occur within 180 days of the date of the closing
of such Public Equity Offering.

   4

         6.       Mandatory Redemption. Except as set forth in Paragraph 7, the
Company shall not be required to make mandatory redemption payments with respect
to the Notes.

         7.       Repurchase at Option of Holder. If a Change of Control occurs,
each Holder of Notes will have the right to require the Company to make an offer
to all Holders to repurchase Notes on the terms, in accordance with the
procedures and subject to the limitations set forth in the Indenture. If the
Company or a Restricted Subsidiary consummates any Asset Sales, when the
aggregate amount of Excess Proceeds exceeds $5.0 million, the Company will be
required to make an offer to all Holders of Notes to purchase the maximum
principal amount of Notes that may be purchased out of the Excess Proceeds on
the terms, in accordance with the procedures and subject to the limitations set
forth in the Indenture.

         8.       Notice of Redemption. Notice of redemption will be mailed by
first class mail at least 30 days but not more than 60 days before the
redemption date to each Holder of Notes to be redeemed at its registered
address. Notices of redemption may not be conditional. Notes in denominations
larger than $1,000 may be redeemed in part. If any Note is to be redeemed in
part only, the notice of redemption that relates to such Note shall state the
portion of the principal amount thereof to be redeemed. A new Note in principal
amount equal to the unredeemed portion thereof will be issued in the name of the
Holder thereof upon cancellation of the original Note. On and after the
redemption date interest ceases to accrue on Notes or portions thereof called
for redemption.

         9.       Denominations, Transfer, Exchange. The Notes are in
registered form without coupons in denominations of $1,000 and integral
multiples of $1,000. The transfer of Notes may be registered and Notes may be
exchanged as provided in the Indenture. The Registrar and the Trustee may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a Holder to pay any taxes and
fees required by law or permitted by the Indenture. The Company or the Registrar
is not required to transfer or exchange any Note selected for redemption. Also,
the Company or the Registrar is not required to transfer or exchange any Notes
for a period of 15 days before a selection of Notes to be redeemed.

         10.      Persons Deemed Owners. The registered Holder of a Note may be
treated as its owner for all purposes.

         11.      Amendment, Supplement and Waiver. Subject to certain
exceptions, the Indenture, the Notes or the Subsidiary Guarantees may be amended
or supplemented with the consent of the Holders of at least a majority in
principal amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes) and any existing default or compliance with any provision of
the Indenture or the Notes may be waived with the consent of the Holders of a
majority in principal amount of the then outstanding Notes (including, without
limitation, consents obtained in connection with a purchase of, or tender offer
or exchange offer for, Notes). Without the consent of any Holder of Notes, the
Company and the Trustee may amend or supplement the Indenture or the Notes to
cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes
in addition to or in place of certificated Notes, to provide for the assumption
of the Company's


   5

obligations to Holders of the Notes in case of a merger or consolidation or sale
of all or substantially all of the Company's assets, to make any change that
would provide any additional rights or benefits to the Holders of the Notes or
that does not adversely affect the legal rights under the Indenture of any such
Holder, or to comply with the requirements of the Commission in order to effect
or maintain the qualification of the Indenture under the TIA.

         12.      Defaults and Remedies. If any Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in principal amount of
the then outstanding Notes may declare all the Notes to be due and payable
immediately. Notwithstanding the foregoing, in the case of an Event of Default
arising from certain events of bankruptcy or insolvency as set forth in the
Indenture, with respect to the Company, any Restricted Subsidiary that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together, would constitute a Significant Subsidiary, all outstanding Notes will
become due and payable without further action or notice. Holders of the Notes
may not enforce the Indenture or the Notes except as provided in the Indenture.
Subject to certain limitations, Holders of a majority in principal amount of
the then outstanding Notes may direct the Trustee in its exercise of any trust
or power. The Trustee may withhold from Holders of the Notes notice of any
continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate
principal amount of the Notes then outstanding by notice to the Trustee may on
behalf of the Holders of all of the Notes waive any existing Default or Event
of Default and its consequences under the Indenture except a continuing Default
or Event of Default in the payment of interest on, or the principal of, the
Notes.

         13.      Trustee Dealings with the Company. The Trustee, in its
individual or any other capacity, may make loans to, accept deposits from, and
perform services for the Company or its Affiliates, and may otherwise deal with
the Company or its Affiliates, as if it were not the Trustee; however, if it
acquires any conflicting interest it must eliminate such conflict within 90
days, apply to the Commission for permission to continue or resign.

         14.      No Recourse Against Others. A director, officer, employee,
incorporator or stockholder, of the Company or any Guarantor, as such, shall not
have any liability for any obligations of the Company or any Guarantor under the
Notes, the Indenture, the Subsidiary Guarantees or for any claim based on, in
respect of, or by reason of, such obligations or their creation. Each Holder by
accepting a Note waives and releases all such liability. The waiver and release
are part of the consideration for the issuance of the Notes.

         15.      Guarantees. This Note will be entitled to the benefits of
certain Guarantees made for the benefit of the Holders. Reference is hereby made
to the Indenture for a statement of the respective rights, limitations of
rights, duties and obligations thereunder of the Guarantors, the Trustee and the
Holders.

         16.      Authentication. This Note shall not be valid until
authenticated by the manual or facsimile signature of the Trustee or an
authenticating agent.

   6

         17.      Abbreviations. Customary abbreviations may be used in the name
of a Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts
to Minors Act).

         18.      Additional Rights of Holders of Restricted Global Notes and
Restricted Definitive Notes. In addition to the rights provided to Holders of
Notes under the Indenture, Holders of Restricted Global Notes and Restricted
Definitive Notes shall have all the rights set forth in the Exchange and
Registration Rights Agreement dated as of the date of the Indenture, between the
Company and the parties named on the signature pages thereof (the "Registration
Rights Agreement").

         19.      CUSIP Numbers. Pursuant to a recommendation promulgated by
the Committee on Uniform Security Identification Procedures, the Company has
caused CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP
numbers in notices of redemption as a convenience to Holders. No representation
is made as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

         20.      Governing Law. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL
GOVERN AND BE USED TO CONSTRUE THIS NOTE WITHOUT GIVING EFFECT TO APPLICABLE
PRINCIPLES OF CONFLICTS OF LAW TO THE EXTENT THAT THE APPLICATION OF THE LAWS OF
ANOTHER JURISDICTION WOULD BE REQUIRED THEREBY.

         The Company will furnish to any Holder upon written request and
without charge a copy of the Indenture and/or the Registration Rights Agreement.
Requests may be made to: Holley Performance Products Inc., 1801 Russellville
Road, P.O. Box 10360, Bowling Green, Kentucky 42102, Attention: Chief Financial
Officer.
