B303 Plus Hydraulic Roller Camshaft for Ford 5.0L HO

The Summit Racing SUM-8901 is a B303 Plus hydraulic roller camshaft that serves as a modernized version of the original Ford Motorsports B303 cam. This billet camshaft is manufactured in the USA and is designed to optimize performance for Ford 5.0L HO engines. Key specifications include 224 degrees of intake duration and 232 degrees of exhaust duration at 0.050 lift. With a 1.6:1 rocker arm ratio, the intake lift is .550 inches and the exhaust lift is .540 inches. The operating RPM range for this camshaft is between 2,800 and 6,250 RPM, with a lobe separation angle of 114 degrees. The firing order is compatible with 5.0L/302HO/351W engines. Installation of the SUM-8901 camshaft requires that piston-to-valve clearance must be checked prior to final assembly. This camshaft is specifically designed for 1986-96 Ford Windsor Roller Blocks and is a direct upgrade for applications using the original Ford Motorsports B303 camshaft.
