At one time, Apten Performance was working on cams for the 4.0. The website is down, but they're still in business. If I remember right, they also had a blower kit which allowed the use of the old T-bird 3.8 blower on the 4.0 motors. These guys aren't cheap either, but cheaper than what I've seen you guys post. May want to try to get a hold of them?
