NOTE 1 - BASIS OF PRESENTATION

The consolidated interim financial statements of Edelbrock Corporation (the
"Company") at September 25, 1999 and for the three month period ended September
25, 1999 are unaudited, but include all adjustments (consisting only of normal
recurring adjustments) which the Company considers necessary for a fair
presentation. The June 30, 1999 balance sheet was derived from the balance sheet
included in the Company's audited consolidated financial statements as included
in the Company's Form 10-K for its fiscal year ended June 30, 1999 (File No.
0-24802).

These unaudited financial statements have been prepared in accordance with
generally accepted accounting principles for interim financial information and
with the instructions to Form 10-Q and Article 10 of Regulation S-X.
Accordingly, they do not include all of the information and footnotes, and
should be read in conjunction with the Company's audited consolidated financial
statements included in the Form 10-K indicated above. Operating results for the
three-month period ended September 25, 1999 are not necessarily indicative of
the results that may be expected for the fiscal year ending June 30, 2000.


NOTE 2 - INVENTORIES

Item 2.   Management's Discussion and Analysis of Financial Condition and
          Results of Operations

The following is a discussion and analysis of the consolidated financial
condition and results of operations of the Company for the quarter ended
September 25, 1999. The following should be read in conjunction with the
Consolidated Interim Financial Statements and related notes appearing elsewhere
herein.

       Overview

The Company was founded in 1938, and is one of America's leading manufacturers
and marketers of specialty performance automotive and motorcycle aftermarket
parts. The Company designs, manufactures, packages and markets performance
automotive and motorcycle aftermarket parts, including intake manifolds,
carburetors, camshafts, cylinder heads, exhaust systems, shock absorbers and
other performance components for most domestic V8 and selected V6 engines. In
addition, the Company offers performance aftermarket manifolds, camshafts,
cylinder heads, air cleaners, and carburetors for Harley-Davidson and other
selected brand motorcycles. The Company currently offers over 3,000 performance
automotive and motorcycle aftermarket parts for street, off-road, recreational
and competition vehicle use.

       Product Mix

The Company manufactures its own products and purchases other products designed
to the Company's specifications from third-party manufacturers for subsequent
packaging and distribution to the Company's customers. Generally, the Company
can achieve a higher margin on those products which it manufactures as compared
to those purchased from third-party manufacturers. Accordingly, the Company's
results of operations in any given period are affected by the product mix of the
Company's sales during the period.

       Manufacturing Capacity

During the most recent peak manufacturing period, the Company used substantially
all of its manufacturing capability for producing its specialty performance
automotive and motorcycle aftermarket parts.

In early October 1999, the Company completed construction of its 65,950 square
foot distribution facility on Company-owned property adjacent to its exhaust
system and shock absorber production facility in Torrance, California. The
Company is utilizing the existing 30,000 square foot distribution area at its
headquarters in Torrance for additional manufacturing capacity.

     Seasonality

The Company's sales are subject to seasonal variations. Customer orders and
sales are greatest in the second, third and fourth quarters of the Company's
fiscal year in anticipation of and during the spring and summer months.
Accordingly, revenues and operating income tend to be relatively higher in the
third and fourth fiscal quarters.

THREE MONTHS ENDED SEPTEMBER 25, 1999, COMPARED TO THREE MONTHS ENDED
     SEPTEMBER 25, 1998:

     Revenues

Revenues increased 13.5% to $25.6 million for the three months ended September
25, 1999 from $22.6 million for the same period of 1998. This increase was
primarily the result of an increase of approximately $614,000, or 26.4%, in the
sale of aluminum cylinder heads, an increase of approximately $706,000, or
10.3%, in the sale of intake manifolds and an increase of approximately $1.5
million or 17.7%, from the sale of carburetors over the similar period of 1998.

     Cost of Sales

Cost of sales increased 17.4% to $15.9 million for the three months ended
September 25, 1999 from $13.5 million for the same period of 1998. As a percent
of revenues, cost of sales increased to 62.0% for the three months ended
September 25, 1999 from 59.9% for the same period of 1998. The increase in cost
of sales as a percent of revenues was mainly due to a change in sales mix toward
outside manufactured products for which the Company achieves lower margins,
increased labor costs associated with additional labor staff, and increased
depreciation in connection with additional capital equipment.

     Selling, General and Administrative Expense

Selling, general and administrative expense increased 8.8% to $6.8 million for
the three months ended September 25, 1999 from $6.3 million for the same period
of 1998. As a percent of sales, selling, general and administrative expense
decreased to 26.6% for the three months ended September 25, 1999 from 27.8% for
the same period of 1998. The increase in expense was due primarily to increased
sales commissions and freight associated with increased sales, increases in
advertising expenditures, and increases in labor costs. The decrease as a
percentage of sales is mainly attributed to a series of ongoing cost controls
and the Company not experiencing costs associated with the Company's efforts
toward the implementation of the QS9000 quality standard this period versus the
same period of 1998.

     Research and Development Expense

Research and development expense increased 15.6% to $784,000 for the three
months ended September 25, 1999 from $678,000 for the same period of 1998. As a
percent of sales, research and development expense increased to 3.1% for the
three months ended September 25, 1999 from 3.0% for the same period of 1998. The
increase was primarily due to an increase in research and development expenses
relating to the Company's ongoing expansion of its product base.

     Interest Expense

Interest expense decreased 2% to $50,000 for the three months ended September
25, 1999 from $51,000 for the same period of 1998. The decrease was primarily
due to a decrease in the principal amount of average debt outstanding.

     Interest Income

Interest income increased 40.6% to $149,000 for the three months ended September
25, 1999 from $106,000 for the same period in 1998. The increase was primarily
due to an increase in the balance of invested funds.

     Taxes on Income

The provision for income taxes increased to $826,000 for the three months ended
September 25, 1999 from $797,000 for the 1998 period. The effective tax rate for
both the 1999 and 1998 periods was approximately 37%.

     Net Income

The Company's net income for the three months ended September 25, 1999 increased
3.6% to $1.41 million from $1.36 million for the same period of 1998. This
increase was the result of the items mentioned above.

LIQUIDITY AND CAPITAL RESOURCES

The Company's liquidity requirements arise primarily from the funding of its
seasonal working capital needs and capital expenditures. Historically, the
Company has met these liquidity requirements through cash flow generated from
operating activities and with borrowed funds under the Company's $2.0 million
revolving credit facility ("Revolving Credit Facility") which expires on
February 1, 2000. The Company expects renewal of this credit facility prior to
expiration. Due to seasonal demand for the Company's products, the Company
builds inventory during the first and second fiscal quarters in advance of the
typically stronger selling periods during the third and fourth fiscal quarters.

The Company believes that funds generated from operations and funds available
under the Revolving Credit Facility together with cash balances will be adequate
to meet its working capital, debt service and capital expenditure requirements
through the next twelve months. The Company has made capital expenditures of
$3.3 million during the first quarter 1999 mainly for the construction of its
new distribution facility and anticipates making additional capital expenditures
of approximately $3.5 - $5.0 million for the remainder of fiscal year 2000
primarily for additional capital equipment to increase production capacity.

YEAR 2000 COMPLIANCE

Computers, software and other equipment utilizing microprocessors that use only
two digits to identify a year in a date field may be unable to process
accurately certain date-based information at or after the year 2000. This is
commonly referred to as the "Year 2000 or Y2K issue," and the Company is
addressing this issue on several different fronts. First, the Company has
requested Year 2000 compliance certification from each of its major vendors and
suppliers for their hardware or software products and for their internal
business applications and processes. Second, the Company has established a
separate team to coordinate solutions to the Year 2000 issue for its own
internal information systems, for which it had completed substantially all
remediation for Year 2000 compliance in the fourth calendar quarter of 1998. As
part of its initial phase of its Year 2000 readiness, the Company installed
Oracle applications and database. In order to complete the Year 2000 readiness
program for its information systems, the Company upgraded its existing Oracle
applications (Version 10.6) to release 10.7 and also upgraded its Oracle
database (to version 7.3.4.4). Amounts incurred in connection with the Year 2000
compliance program were not material to the Company's financial condition or
results of operations. The Company does not believe that its business will be
adversely affected by the Year 2000 issue in any material respect. Nevertheless,
achieving Year 2000 compliance is dependent on many factors, some of which are
not completely within the Company's control, including without limitation, the
availability and cost of trained personnel and effectiveness of software
upgrades used by the Company and its vendors and suppliers. Should either the
Company's internal systems or the internal systems of one or more significant
vendors or suppliers fail to achieve Year 2000 compliance, the Company's
business and its results of operations could be adversely affected. For Year
2000 issues which, if not timely resolved, could have a significant impact on
the Company's operations, the Company has developed


                                       9

contingency plans. These plans include utilizing alternative vendors and service
providers and have been designed to minimize the impact of failure to achieve
Year 2000 compliance.

"SAFE HARBOR" STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF
1995:

 Any statements set forth above which are not historical facts are
forward-looking statements that involve known and unknown risks and
uncertainties that could cause actual results to differ materially from those in
the forward-looking statements. Potential risks and uncertainties include such
factors as the financial strength and competitive pricing environment of the
automotive and motorcycle aftermarket industries, product demand, market
acceptance, manufacturing efficiencies, new product development, the success of
planned advertising, marketing and promotional campaigns, the success of the
Company's, its vendors', and its suppliers' Year 2000 compliance programs and
other risks identified herein and in other documents filed by the Company with
the Securities and Exchange Commission.

Item 3.   Quantitative and Qualitative Disclosure About Market Risk

The Company's exposure to interest rate changes is primarily related to its
variable rate debt which may be outstanding from time to time under the
Company's Revolving Credit Facility with Bank of America, NT & SA. The Company's
Revolving Credit Facility is a $2 million line of credit with an interest rate
based on the prime rate (currently 8.25%) and expires on February 1, 2000.
Because the interest rate on the Revolving Credit Facility is variable, the
Company's cash flow may be affected by increases in the prime rate. Management
does not believe that any risk inherent in the variable rate nature of the loan
is likely to have a material effect on the Company. As of September 25, 1999,
the Company's outstanding balance on the Revolving Credit Facility was zero.
Even if the Company were to draw down on the line prior to its expiration and an
unpredicted increase in the prime rate occurred, it would not likely have a
material effect.

          Sensitivity Analysis

To assess exposure to interest rate changes, the Company has performed a
sensitivity analysis assuming the Company had a $1 million balance outstanding
under the Revolving Credit Facility. The monthly interest payment, if the rate
stayed constant, would be $6,875. If the prime rate rose 100 basis points, the
monthly interest payment would equal $7,708. The Company does not believe the
risk resulting from such fluctuations is material nor that the payment required
would have a material effect on cash flow.
