1969 Mustang Sportsroof AKA Nasty is the lovechild of a Shelby GT500 and ’69 Mustang

Featured in the January, 2012 issue of Modified Mustangs & Fords, this nasty 1969 Mustang Sportsroof is an Erich Bollman original creation, and boy is it unapologetic! The New Castle, Delaware-based Ford fanatic runs a family-owned, restoration and custom build shop called Christiana Muscle Cars, his expertise in the area inspired him to try and mate the new GT500 engine sourced from Ford Racing Performance Parts with a 1969 Mustang body. The unlikely offspring that the marriage produced is over-the-top to say the least. Bollman roped in the services of designer Murray Pfaff and the project was dubbed “Nasty” as a tribute to Bollman’s high school best friend, Nicu Nastase.

Producing 480 lb-ft of torque at 4,500 rpm and 500 hp at 6,000 rpm, the Shelby GT500 5.4L DOHC Crate Engine used on Nasty. Fitted with Eaton Roots-style supercharger, the engine on the mod comes with aluminum four-valve cylinder heads, and cast-iron cylinder block. JDM Engineering provided the custom computer tuning on the vehicle and the beast also comes fitted with custom cold-air induction tube and an aeromotive fuel system. To cradle the 837-pound, supercharged powerplant, a custom front subframe was fabricated by Bollman’s staff. To ensure they didn’t cover the entire wheel in the wheelwell, a set of 19-inch wheels was used to get optimum ground clearance.
