Recent dyno testing at Adrenaline Autosports, in Chatsworth, CA, on a mildly built Ford 302, fitted with stock 289 heads, revealed incredible results. Baseline numbers with a 600-cfm Holley carb and no spacer produced 218.57 rear wheel horsepower at 5500 rpm with 252.97 ft-lbs. of torque. The carb was switched to a 680-cfm QFT street carb, manufactured with a Proform® carb main body, and one pull was made with each of the three variations of Proform 1-inch phenolic spacers supplied in their Trackside Carb Spacer kit.
The wide open spacer proved to be the most efficient for this engine, producing a whopping 244.62 rear wheel horsepower with 276.55 ft-lbs. of torque, equating to a 12% HP increase and , a 9% torque increase. That’s a gain of 26.5 horsepower and 23.58 ft-lbs. of torque with only a carb change and spacer install. We broke down the numbers for the spacer only, and this simple change resulted in an increase of 14 rear wheel horsepower and 9 ft-lbs. of torque. Incredible! and the 3-in-1 spacer kit is under $80. Now that’s a low cost power adder producing astounding results!

By simply changing the carb and adding the Proform 67160C spacer to this engine, we gained increased throttle response, realized the full power band of the engine, and at wide open throttle it felt like it would never stop pulling. That, coupled with the horsepower and torque increase, makes this combination a winner on street or strip.

Edelbrock has posted a tech tip titled Cleaning Your Edelbrock Aluminum Intake Manifold

Edelbrock Tech Tip:
Cleaning Your Edelbrock Aluminum Intake Manifold

While networking with consumers at shows and events, we learn a lot about our customer and what they want from Edelbrock. The old adage, “necessity is the mother of invention” is very true in most cases. This leads us to the question that has incited us to write this Edelbrock Tech Tip feature, “How do you recommend I clean my Edelbrock intake manifold”?Edelbrock intake manifolds are manufactured from a sand cast process utilizing 808 aluminum alloy and have an as-cast wheel-a-brated finish. As-cast is defined as a raw aluminum finish without any protective coating. As-cast aluminum is porous and can absorb under-hood chemicals such as dirt, grease and fuel, resulting in discoloration, rust, or staining. All Edelbrock intake manifolds are as-cast unless offered in our high-luster EnduraShine™ or PermaStar® coated finishes.

Once a porous aluminum finish is stained, it can be very difficult to find an environmentally safe cleaner that will actually extract the blemish from the pores of the aluminum. In our research in finding a safe and effective alternative, Edelbrock has found an aluminum cleaner option that can work effectively, OxiSolv Aluminum Cleaner. It is important to follow OxiSolv’s instructions to prevent damage to other parts on your engine.

Manufactured by OxiSolv, a manufacturer of industrial and commercial cleaning products, OxiSolv Aluminum Cleaner is effective for use in cleaning our as-cast aluminum intake manifolds, cylinder heads, and water-pumps when used as directed. Edelbrock does not sell OxiSolv, however you can visit the following websites for additional product information and locations on where to purchase.
