In that time they have built several amazing projects such as this 1974 IROC clone. The company started with a 1974 Porsche 911 which was stripped completely down to the body. After reinforcing the chassis and installing a roll cage it was painted in Grand Prix White L-908. Power comes from a 964 based 3.8 L flat-six engine and with help from the billet slide valve ITB it produces 380 horsepower. Connected to the engine is a RUF six-speed transaxle based on a G-50\/50 transaxle.<\/p>\n<p><a
