If you have a street
duty engine please read the following descriptions to help
you decide which of our product lines that best suited for
- Cams designed to work with computer systems and to comply
with emission standards as well. In general, these cams are
low RPM cams with very smooth idle.
High Energy -
These high torque cams work very well on the street. Made
for use with engines having a 9:1 CR or less. They can be
used in conjunction with most stock components, including
intake and exhaust manifolds, and carburetors. Normally, gas
mileage will either remain the same or increase over a stock
Dual Energy -
These cams have more duration and lift on exhaust than
intake. Designed for applications where a sacrifice in low
end is acceptable for an increase in mid and upper range RPM
horsepower. They should be used in conjunction with an
exhaust system that is much more restrictive than the intake
These cams are very aggressive, designed for performance
oriented vehicles where they will see little street use.
Stock components are generally incompatible. Changes are
needed in rear end gear ratios, headers and the torque
converter. Magnum Cams are available in the following lifter
Hydraulic Flat Tappet -
Features anti-pump-up flat tappet
hydraulic lifters, providing a good compromise between low
maintenance requirements and performance capabilities.
Hydraulic Roller - Has all
of the abilities of the hydraulic flat tappet, but when
paired with the required roller lifters, the lobes can be
designed to provide higher torque output and a smoother idle
for the same RPM range.
- These camshafts are designed to
maximize performance from engines equipped with nitrous
oxide or supercharging, but the carefully tailored profiles
deliver strong performances without nitrous; however, they
offer incredible gains with nitrous.
These cams are Comp Cams newest series
of hydraulic and hydraulic roller cams. They are designed to
take advantage of the latest improvements in valve train
components and the newest developments in camshaft design.
Their aggressive lobe design produces better throttle
response and top end horsepower that other cams with the
same duration @ .050", while delivering increased engine
Solid Flat Tappet -
The lifter uses solid lifters,
therefore the customer must want higher performance at
higher RPM. The customer must also be unconcerned with valve
Solid Roller -
Uses a solid roller lifter, therefore, it can be made to be
more aggressive than a hydraulic roller. For use in high
performance applications where the ultimate concern is
performance potential at higher RPM. Periodic checking of
the valve lash must not be a problem.
