One of the most difficult stories to do in the performance-magazine world is a direct component comparison. This manifold is able to accommodate all three of those cylinder-head choices. We upgraded the heads to a pair of TFS Super 23 aluminum castings to ensure we got the most out of each intake. I bought a couple of Edelbrock and one Offy due to people's claims of them making more power. Manage Content in This Topic. Ad Management plugin by RedTyger. An excellent old true high-rise dual plane, imho!!
This intake fits a gasket o Making comparisons with the AirGap theory held true, however, and the AirGap held a significant torque advantage all the way up the scale over the single-plane. Last edited by 2wld4u; at Though technically any intake manifold can be seen as a simple conduit for the air-fuel mixture, there are a wide variety of designs on the market, with each designed and created to handle the job a little differently. High flow cylinder heads highly recommended.
Note that passwords are case-sensitive. A single-plane, open-plenum intake would obviously be easier to design and cheaper to build, so why bother with a two-plane? Read on for the lowdown on what we found. Contact Us - Hot Rod Forum: Already know the part number you need?
