very nice. Are you going to get him to make up 2 manifolds? may be cheaper and then you can sell the other manifold with the 2carbs u don't use... just a suggestion
I dont think it will be possible to use the other two carbs, as the two end carbs (the ones im planning on using), one has the throttle linkage and the other has the tps on it, so to be able to use the other two, they would need these fitted.
