The Edelbrock carb adapter adds another 0.850″ of height to your carb setup, so please keep this in mind if there’s a chance that a lack of hood clearance could be an obstacle. To use an OE-style spread bore carb, such as a Quadrajet (Q-Jet), you will need to use a carb adapter. … Edelbrock 2701 The Edelbrock 2701 intake manifold is designed to mate with a square bore carburetor. For example, the Edelbrock 2101 can fit under a stock Chevy Corvette hood. At 4.050″, it is slightly shorter than the 2701, which matters most for vehicles with limited hood clearance.
The Edelbrock 2101 carries a higher price tag as a result.Ī less obvious difference is its height. It is designed, machine-finished, and bored in such a way that it can mate with either a spread bore or square bore carburetor. The Edelbrock 2101‘s primary differentiating trait from its 2701 cousin is its flange design at the top center of the intake manifold. … Edelbrock 2101 The Edelbrock 2101 intake manifold is designed to work with either a square bore, or spread bore carburetor. If you do not own a first-gen small block Chevy, there’s a good chance you should be shopping for intake manifolds other than these two. Port-style matching and alignment are important when choosing an intake manifold. (The 2701 is taller.) Your hood clearance will depend on your specific application and setup, but it’s an important consideration in the event of any space issues you might run into.įurthermore, Edelbrock 21 intake manifolds are machined specifically to mate to a Gen. Regarding fitment, a little more than two tenths of an inch (0.220″, to be exact) separate the heights of these two manifolds. You can learn more about the differences between them by watching this short Edelbrock explainer video: If you’re shopping for an intake for a high-horsepower engine or race car, you might want to consider a single-plane intake manifold. Each plenum feeds just four cylinders on your V8 engine.ĭual-plane manifolds have longer intake runners than a single-plane design and are ideal for low- to mid-range power production in the 1,500-5,500 rpm range, which results in good idle quality. Single-plane manifolds, dual-plane manifolds, and tunnel ram manifolds are three common, popular styles.īoth the Edelbrock 21 are dual-plane manifolds, which means they both have two separate plenums. There are three basic steps to choosing the right intake manifold: This article aims to highlight the differences between the Edelbrock 21 intake manifolds to help you choose the best Edelbrock Performer dual-plane intake for your vehicle. Similarities, and both are capable, proven options for street performance and The Edelbrock 2101 and the Edelbrock 2701 are both carbureted, dual-plane intake manifolds that are part of the popular Edelbrock Performer product line.īoth of these Edelbrock intake manifolds share several
