I have a 427 in my superformance and when the problems were beyond my ablities, you need a local guy that you can talk to and look in the face. I like to do everything myself and like to understand what is going on. I got the recommendations from this forum for a good FE builder and came up with someone that was great, Phil Miller Machine in Haverhill Ma.
I am sure that you can find someone in your own back yard that will do an excellent job.
After saying all that I must add that I want a Shelby Aluminum someday and the people with the most experience (well publized experience) are Southern Automotive, Gressford and Keith Craft. Keith Craft is my favorite because of there head work.
