RPM range shown is for average usage. These cam profiles
will RPM higher, depending upon application.
IMPORTANT NOTE: Crane Hydraulic Roller Cams offer tremendous
power, torque and RPM potential. Due to their RPM capability
and increased valve travel, it is HIGHLY RECOMMENDED
that the appropriate Crane valve train components be
installed for maximum performance and reliability.
NOTE: The camshafts listed above incorporate the front ignition
drive pilot hole for late model applications. A long cam
dowel pin is installed, which can be driven in further when
required for short dowel pin application engines.
NOTE: 1988-99 Chevrolet 305 and 350V-8 engines (and some 1987
350V-8 engines) use a different configuration camshaft core
than the 57-87 engines and cannot be interchanged.
Since 1975, General Motors divisions have exchanged engines
