Goat Built is a GREAT source for some unique and specialized relocation brackets designed specifically for the Vortec Truck / SUV engines.

Drew Burroughs at Goat Built designed and built a competitive Rock Crawler / Ultra4 chassis around the Vortec engine and markets it to the home fabricator.  Nick-named, "buggy in a box", the complete chassis comes pre bent and notched in a box ready to weld.
