487 CAM - The 487 Reaper CHOP is a great all-around camshaft and Feulings go to for 4 1/2 stroke 114 - 117 looking for an agressive bolt-in. The 487 has that nasty CHOP idle sound while producing a wide powerband that the Feuling cams are known for. Responds very well to increased bore and or compression, exhaust system and air cleaner. Use of performance valve-springs is not required but may result in a quieter, smoother running valve-train See Feuling #1107 or #1108.
