Obsidian SG-One
One of the things I love about going down to JBA is that there’s usually something interesting on the dyno. Today, it was the Obsidian SG-One, a unique 1967 Mustang that, according to the builder, has $1.3 million invested. Speed shop general manager and tuning guru Bruce Tucker was on the laptop, tweaking the BigStuff3 standalone to dial it in.
