You are correct, sir. The air cleaner is north of 750 not including the top which is another 125. The linkage kit is also around 700. What this means is you could very easily wrap up 3000 bucks. I'm thinking 2 x 4 might be way cheaper in the long run...especially since I have a brand new Eddy performer 500 cfm carb here. One more of them and a manifold might make for a really hot time in the old town. Didn't you have a SB dual quad setup once, Rumble? I seem to remember a video of one here once upon a time.
