The legendary B303 cam developed by Ford Performance for the 5.0L Fox-body Mustang. This cam provides a noticeable power improvement and lumpy idle while maintaining good driveability with a manual transmission. Works well with carburetors or mass air fuel injection.

Camshaft intake and exhaust valve events are measured at 0.050" tappet lift. The duration figures in the shaded area are taken at 0.050" tappet lift. This is useful to check the cam with a degree wheel during installation. The solid colour is advertised duration. For comparison purposes, add intake and exhaust lobe centres and divide by 2 to calculate "camshaft centerline" specification for Ford Performance camshafts.

Made by Ford Performance Parts (Ford Motor Company). Genuine Ford Racing Parts, backed by Ford Motor Company's factory engineering and warranty.
