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: 1997-up Chevrolet 5.7L LS1/LS6, 1988-99 305 and 350V-8
(and some 1987 350V-8) engines, and the 1957-87 262-400
V-8 engines, each use different configuration camshaft
cores, and cannot be interchanged.
Since 1975, General Motors divisions have exchanged engines
throughout different models. Be certain of exactly which
engine you have before ordering.
Crane Cams offers many different cam lobe profiles for the GM“LS1/
LS2/LS6 Engine Family”.These hydraulic roller cams are
designed for applications ranging from mild street performance
upgrades, serious torque and HP increases for trucks,
4.8 - 5.3 - 5.7 (346) - 6.0 - 6.2L LS1, LS2, LS3/L92, LS6

to all-out competition profiles for LS1 powered race cars.
Crane’s LS engine family’s grinds are designed to take optimum
advantage of the LS1/LS2/LS6’s lighter valve train and
greated reduced component inertia.This low inertia allows
extraordinarily quick valve acceleration rates.This actually
increases the“area beneath the lift curve”in each profile.
Simply put, they begin moving the valve off its seat at a
much quicker rate, to initiate earlier flow.The profiles retains
and lengthens this rate of acceleration during the valveopening
cycle and as it approaches maximum valve lift.They
function like a much“bigger”cam (greater duration) yet
they increase low-end and mid-range torque in the most
often used rpm range. Peak horsepower and torque output
are enhanced throughout the entire rpm range.The valve lift
tables were also designed to minimize horsepower-robbing
harmonic frequency pulses when matched with the recommended
Crane valve springs and pushrods.
Crane Cams are absolutely the most powerful performance cams
available today, and represent the very latest in cuttingedge
cam design and valve train technology for the Chevy
LS1/LS2/LS6 engine family in Camaros, Firebirds, the Pontiac
GTO (2005), Corvettes, and Chevy and GMC trucks.

*This product is applicable only to pre-1966 California and pre-1968 federally certified passenger cars. It
is also applicable to non-emission controlled trucks and similar vehicles. It is not applicable or intended
for use on any emission controlled vehicles operated on highways or roads.

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: 1997-up Chevrolet 5.7L LS1/LS6, 1988-99 305 and 350V-8
(and some 1987 350V-8) engines, and the 1957-87 262-400
V-8 engines, each use different configuration camshaft
cores, and cannot be interchanged.
Since 1975, General Motors divisions have exchanged engines
throughout different models. Be certain of exactly which
engine you have before ordering.
Crane Cams offers many different cam lobe profiles for the GM“LS1/
LS2/LS6 Engine Family”.These hydraulic roller cams are
designed for applications ranging from mild street performance
upgrades, serious torque and HP increases for trucks,

to all-out competition profiles for LS1 powered race cars.
Crane’s LS engine family’s grinds are designed to take optimum
advantage of the LS1/LS2/LS6’s lighter valve train and
greated reduced component inertia.This low inertia allows
extraordinarily quick valve acceleration rates.This actually
increases the“area beneath the lift curve”in each profile.
Simply put, they begin moving the valve off its seat at a
much quicker rate, to initiate earlier flow.The profiles retains
and lengthens this rate of acceleration during the valveopening
cycle and as it approaches maximum valve lift.They
function like a much“bigger”cam (greater duration) yet
they increase low-end and mid-range torque in the most
often used rpm range. Peak horsepower and torque output
are enhanced throughout the entire rpm range.The valve lift
tables were also designed to minimize horsepower-robbing
harmonic frequency pulses when matched with the recommended
Crane valve springs and pushrods.
Crane Cams are absolutely the most powerful performance cams
available today, and represent the very latest in cuttingedge
cam design and valve train technology for the Chevy
LS1/LS2/LS6 engine family in Camaros, Firebirds, the Pontiac
GTO (2005), Corvettes, and Chevy and GMC trucks.
