Edelbrock Rollin' Thunder Performer RPM Hydraulic Roller Cams for Mustang with a 351W Engine Block.
These cams feature more aggressive profiles than conventional cams without excessive valve overlap. Roller tappets reduce friction, virtually eliminate break-in problems and permit higher valve velocities for increased performance. RPM range is 1500-6500rpm.
Intended for use with OEM or Edelbrock hydraulic roller tappets.
