               NOTES TO CONSOLIDATED INTERIM FINANCIAL STATEMENTS



NOTE 1 - BASIS OF PRESENTATION

The consolidated interim financial statements of Edelbrock Corporation (the
"Company") at September 25, 2000 and for the three month period ended September
25, 2000 are unaudited, but include all adjustments (consisting only of normal
recurring adjustments) which the Company considers necessary for a fair
presentation. The June 30, 2000 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, 2000 (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

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, 2000. 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 3,200 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 a substantial
portion of its manufacturing capability for producing its specialty performance
automotive and motorcycle aftermarket parts.

        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, 2000, COMPARED TO THREE MONTHS ENDED
        SEPTEMBER 25, 1999:

        Revenues

Revenues remained substantially unchanged, increasing 0.1% to $25.7 million for
the three months ended September 25, 2000 from $25.6 million for the same period
of 1999. This slight increase was primarily the result of an increase of
approximately $421,000, or 4.3%, in the sale of Edelbrock automotive
carburetors; an increase of approximately $183,000, or 24.8%, in the sale of
Performer IAS shock absorbers; an increase of approximately $154,000, or 41.5%,
in the sale of fuel injection systems, mainly offset by a decrease in sales in
aluminum intake manifolds of approximately $687,000, or 9.6%.

        Cost of Sales

Cost of sales decreased 1.3% to $15.7 million for the three months ended
September 25, 2000 from $15.9 million for the same period of 1999. As a percent
of revenues, cost of sales decreased to 61.1% for the three months ended
September 25, 2000 from 62.0% for the same period of 1999. The decrease in cost
of sales as a percent of revenues was mainly due to production efficiencies
related to the installation of efficient computer-controlled CNC machining
centers.

        Selling, General and Administrative Expense

Selling, general and administrative expenses increased 4.2% to $7.1 million for
the three months ended September 25, 2000 from $6.8 million for the same period
of 1999. As a percent of sales, selling, general and administrative expense
increased to 27.7% for the three months ended September 25, 2000 from 26.6% for
the same period of 1999. The increase in expenses and as a percentage of sales
were partly due to increases in depreciation and related expenses associated
with the Company's distribution center which became operational in October 1999.
In addition, the increase also resulted from increased advertising and marketing
expenditures.

        Research and Development Expense

Research and development expense remained substantially unchanged, decreasing
0.3% to $782,000 for the three months ended September 25, 2000 from $784,000 for
the same period of 1999. As a percent of sales, research and development expense
decreased to 3.0% for the three months ended September 25, 2000 from 3.1% for
the same period of 1999.

        Interest Expense

Interest expense decreased 4.0% to $48,000 for the three months ended September
25, 2000 from $50,000 for the same period of 1999. The decrease was primarily
due to a decrease in the principal amount of average debt outstanding.

        Interest Income

Interest income decreased 18.8% to $121,000 for the three months ended September
25, 2000 from $149,000 for the same period in 1999. The decrease was primarily
due to a decrease in the balance of invested funds.

        Taxes on Income

The provision for income taxes decreased to $804,000 for the three months ended
September 25, 2000 from $826,000 for the 1999 period. The effective tax rate for
both the 2000 and 1999 periods was approximately 37%.

        Net Income

The Company's net income for the three months ended September 25, 2000 decreased
2.9% to $1.37 million from $1.41 million for the same period of 1999. This
decrease 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, 2002. 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
approximately $1.0 million during the first quarter of fiscal year 2001 mainly
for new machinery and equipment and anticipates making additional capital
expenditures of approximately $3.5 - $5.0 million for the remainder of fiscal
year 2001 primarily for additional capital equipment to increase production
capacity.

"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, 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 9.50%) and expires on February 1, 2002.
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, 2000,
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 $7,917. If the prime rate rose 100 basis points, the
monthly interest payment would equal $8,750. 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.
