Haven't spoken with Art personally that I am aware of, but I have friends who have. He casts a lot of parts for other engine families besides the FE, and they sell quite well. Demand is always a key factor on determining what to cast, stock, or warehouse. Maybe if someone would place an order for 50-100 manifolds it would get his attention and speed things up. Takes money to make things happen in this economy. Just saying---Joe-JDC
