• Deeper scavenge kidney ports over the HP+ series for even more scavenge flow volume
• Race Series® hydraulic lifters have a full .200" of total travel designed with a slower bleed down rate to handle heavy valve spring pressures, increase engine rpm before valve float and feature increased roller clearance for steep ramped camshafts and clearance for the M-Eight front exhaust camshaft lobe flange.

521 Cam

• Aggressive pulling power with a "nasty" sound, the Reaper 521 grind will shine in 114" and larger cubic inch engines with added compression ratio
• Requires high lift valve springs; see PART #0926-2973 or 0926-2974
• Stock throttle body produces an excellent powerband; use of a high-flow throttle body may increase peak power numbers
• 2250 - 6250 rpm range
• Ported cylinder heads are not required, but will complement the cam and add even more pulling power throughout the range
• A high-flow exhaust system and air cleaner is highly recommended for optimal performance
• Feuling recommends matching 521 cam with Race Series oiling system PART #0932-0199
• Heavy-duty one-piece pushrods are also highly recommended
