The blocks are "cast" by Buddy Bar Casting Co. The "patterns" or "molds" were made by Scott Powers Patternworks & developed using original Ford blue prints (Not Donovan or hemi or anything else). The "CNC" machine work was originally done by Arias but Shelby bought the "engine machine shop" from them in 2003, so they currently machine their own blocks, heads, and support components.
As for the Goodyear race tire distributorship it has move to Las Vegas but is still owned by Carroll.
