Ford E303 Cam
This Ford Performance E303 hydraulic roller cam, also known as an E303 cam, is a great way to add horsepower to your 5.0L 85-95 Mustang. Fox Body cams not only add performance, but they also give your Mustang an aggressive lope exhaust tone. This Mustang E Cam (M-6250-E303), offers good idle quality and excellent low and mid range power for your 302 engine. While it adds a noticeable power improvement, it still maintains great drivability characteristics for daily driving. Works well with a manual transmission, automatic transmission, carburetor, and mass air fuel injection.
