Feuling Chain Drive Reaper Camshaft for Harley Milwaukee 8 M8 17-25

405 CAM - A workhorse, producing a wide powerband increasing torque and HP throughout the entire RPM range when compared to stock. Direct bolt in replacement for Milwaukee Eight engines, can be used with stock valve springs, pushrods, lifters and exhaust. Will respond well with slip-on mufflers and or complete exhaust system and a high flow air cleaner. Note Feuling recommends using free flowing mufflers with smaller cores for best lower RPM power and pull. RPM range 1,700 - 5,700. Grind: 405

This direct bolt in replacement for Milwaukee Eight engines can be used with stock valve springs, pushrods, lifters and exhaust. Will respond well with slip-on mufflers and or performance 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. This cam will also respond well with increased bore and or compression.

472 CAM - The 472 Reaper is a great all-around camshaft and Feulings go to for 4 1/2 stroke 114 - 117 looking for a little more than our 465 grind and wanting a bolt-in. The 472 has a great bottom end with substantial gains above 2,800 RPM when compared to stock. 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.

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.

508 CAM - The Grim Reaper Aggressive pulling power with a nasty sound. This camshaft revs up faster than the 521 grind, sounds nastier and pulls harder but is more difficult to tune. The REAPER 508 grind will shine in 114 and larger cubic inch engines with added compression ratio. Ported cylinder heads are not required but will complement the cam and add even more pulling power throughout the range. The stock throttle body produces an excellent powerband and use of a high flow throttle body will increase peak power numbers. A high flow exhaust system and air cleaner is highly recommended for optimal performance. FEULING recommends matching this cam with our RACE SERIES oiling system.

NOTE: High Lift valve springs are required on stock cylinder heads, see FEULING BEEHIVE valve spring kit #1107 (DRAG# 0926-2973) or #1108 (DRAG# 0926-2974). SE cylinder heads have high lift valvesprings and will accept the 508 and 521 grind cam. Heavy Duty one piece pushrods are also highly recommended see #4087.
