shop that will be knowledgeable enough to do the work you will need. Are you doing the assembly? Have you ever built an engine before? There is a lot you need to know that isn't part of a typical build. Also, the build you listed is VERY expensive. The transmission alone that is listed is around $7,000 before shipping.
My opinion is this isn't a build someone will be able to talk you through on a forum. If you are truly serious about a build like this talk to one of the engine builders on this forum and have them build it for you.
