Hi John, I am a tight fisted git so throttle bodies are out of my league. I am at a fairly early stage of modding the manifold, I have no idea if it will turn out OK or not but it sounds like a fine plan when I run it through in my head
I have done the design for it (again in my head) and have cut the original down but am now waiting for some ally and some duraweld before I can start making the new one up.
Best and all that,
Dave
