Flat
Tappet CAMSHAFTS
Hydraulic
and Mechanical
A NEW
GENERATION OF CAM PROFILES
We are proud to introduce you to Camcraft's new XTL series of flat tappet cam
profiles. These are our own state of the art computer designs. Camcraft has
retained a world renown camshaft design consultant with over 50 years experience
to develop these profiles, featuring large nose radius, maximum velocity, high
opening acceleration, lower closing acceleration, and very low jerk values.
These are tight lash
mechanical lifter profiles.They were designed to permit the use of hydraulic
lifters where required by class rules. Ther are profiles for .842, .874 & .904
lifters
The masters for these
profiles were made directly from 8 place design data on a $750,000.00 CNC cam
grinder, thus eliminating the errors and design corruption
found in most models and masters. They are primarily aimed at 1/4 to 5/8 mile
oval track and bracket racing with rpm ranges up to 73-7600. These proven
designs have a very successful history over the past years especially in the
NASCAR LMS cars. They have a very flat torque curve, offer very good valve train
life, and they are very responsive to lash changes. Camcraft delivers the
power
to run up front with
reliability
to finish the
race.
These profiles are also
popular with Bracket Racers who choose not to run Roller cams. The broad torque
curves launch the car very hard and still pull better MPH on top end.
XTL Series
of flat tappet profiles for .842 lifters.
