A 505-horsepower version of this 'Cammer' motor has already proven itself in several races, such when it won the 24 Hours of Daytona. As impressive as that number is, it is really easy to get even more power from the engine. This 'Cammer' engine produces a healthy 440 horsepower at the flywheel. This engine comes ready to race right out of the box, boasting features such as an 11.0:1 compression ratio, ported heads, and higher-lift cams. Ford has dropped Ford Racing Performance Parts' 5.0-liter V8 'Cammer' crate engine into the GT-R. The engine is truly the most important part of any car, and the Mustang GT-R Concept's motor is a true beauty. Based on the upcoming 2005 Mustang, the GT-R Concept has been thoroughly reworked to be the ultimate road-racing machine. This car was put together by Saleen, so you know that it is a Mustang done right. Unlike the mis-badged Mustang GT-R's we mentioned, Ford's Mustang GT-R Concept truly is worthy of the GT-R badge. However, it seems that Ford likes the 'GT-R' moniker, as it has made its own Mustang GT-R Concept. Oh, how we used to mock the Mustang owner who thought their GT-R badge was cool. These Mustangs were typically the underpowered GT base models from the mid-1990's. We all used to laugh at the Mustangs we have seen running around with Skyline GT-R badges.
