power, torque and RPM potential. Due to their RPM capability,
and to insure that correct components are used, the
appropriate CamPonent Kit is recommended. Each Crane
CamPonent Kit contains the valve train components needed
for maximum performance.
IMPORTANT: AdjustableVacuum Advance Kits available. See page
