Feuling, Reaper Race Series 508 camshaft kit

Chain drive.
This Feuling M8 cam kit includes chain drive camshaft, Race series lifters and a camshaft installation kit comprising camshaft bearings, camshaft/crankshaft hardware and a gasket/O-ring kit that allows installation of the factory one-piece pushrods. Feuling recommends the optional Feuling 993528 one-piece high-strength HP+ pushrod kit, with a 0.165" wall thickness.
The Feuling 707450 rocker box fastening kit is also highly recommended to help prevent head cracking; this kit replaces the rocker arm shaft bolts with studs and nuts to reduce stress on the rocker arm shaft spacers.
HP+ kits include HP+ lifters and RACE SERIES kits include RACE SERIES lifters.
508 CAM - "The Grim Reaper" Aggressive pulling power with an "aggressive" sound. This camshaft accelerates faster than the 521 profile, has a more aggressive sound and pulls harder, but is more difficult to tune. The REAPER 508 profile will excel in 114" and larger engines with higher compression ratios. Ported heads are not mandatory, but will complement the camshaft and add even more pulling power throughout the range. The stock throttle body produces an excellent power band, and using a high-flow throttle body will increase peak power figures. A high-flow exhaust system and air filter are strongly recommended for optimum performance. FEULING recommends pairing this camshaft with the RACE SERIES 707407 lubrication system.
NOTE: High-lift valve springs are required on the stock cylinder heads; see FEULING beehive valve spring kit 993530 or 588021. SE heads have high-lift valve springs and accept the 521 profile camshaft. High-strength one-piece pushrods are also highly recommended; see 993528.
The kit includes only the 993526 camshaft. RPM range: 2,250 - 5,900. Profile: 508

• The RACE SERIES hydraulic lifters have a full total travel of .200", designed with a slower bleed rate to handle high valve spring pressures, increase engine RPM before valve float, and feature increased roller clearance for steep ramp camshafts and clearance for the M8 front exhaust cam lobe flange.
