Feuling 521 Cam For Harley

521 Cam has aggressive pulling power with a nasty sound, the Reaper 521 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.

Features:

Aggressive power with a nasty sound
RPM range 2,250-6,250
Ported cylinder heads are not required but will complement the cam
High lift valve springs required
High performance pushrods and lifters recommended
Made in the USA
