I purchased this Offenhauser 2x4 intake for a Dodge 315 Hemi that I built (see picture). I came into three almost new Stromberg 97 carbs and since I had a 3x2 intake I have decided to go that route for my project. This intake was a new NOS intake when I purchased it last year and has only been used to break in my motor on my run stand. The carbs are two 500 CFM Edelbrock (Carter/AFB) that were rebuilt when I purchased them from a fellow that has a small rebuilding business on the side. The rebuilder added a special reducer (seen in the one picture) that effectively reduces these carbs to 400 CFM. This restrictor can be removed if you ever want to go back to 500 CFM. The one carb is a 4758S and the other is a 4715S. One has a manual choke and one does not (typical for 2x4 set-ups). The carbs were purchased as a pair and were rebuilt with Walker kits. Both have nice tight throttle shafts. The specs on the carbs are: 86 Primary 71 Secondary 68-47 Rods 7" Hg Springs Also included Non-Stick Base Gaskets, Air Cleaner Gaskets, Original Jets and Rods, etc. In addition to the carbs, intake and spacers, I am also including the Edelbrock linkage I purchased, fuel line, two new intake gaskets and a set of stainless bolts to simplify your installation. I plumbed the carb spacers to run a vacuum line back to where I mounted an adjustable PCV valve. I am keeping the PCV valve but if you do not want the extra vacuum line you can easily remove it and cap the line (or ports). The price includes FREE SHIPPING to the lower 48 states or pick up in Charleston, WV. Feel free to ask questions.
