If your willing to truck it over to Riverside, California from Arizona, you have one of the top FE builders in the country there...Robert Pond Motorsports. Here's the link:
He also forges the best aluminum or iron FE blocks in the world. Keith Craft, Barry Robotnick, Genesis...all use his blocks. He's also a real gentleman, to boot.
I had Keith Craft build mine, he has tons of experience, did a great job at a reasonable price, and has shipping outfit he uses a lot and gave me a break on that as well. Keith Craft Performance Engines
Another vote for Keith Craft. He built my 427 FE side oiler (NASCAR block). Also he advertises on this site. It is best to call and speak with them.
