1 Chevrolet V cu.in. CAMSHAFTS Application Mechanical Lifter Camshafts Excellent low end and mid range torque and HP, fair idle, moderate performance usage, bracket racing w/ heavy car, off road, auto trans w/2000+ converter, cruise RPM, 0.5 to.5 compression ratio advised. Good low end and mid range torque and HP, fair idle, moderate performance usage, bracket racing, auto trans w/2000+ converter, also w/plate or manifold nitrous system, cruise RPM, 0.5 to.5 Good w/centrifugal or Roots supercharger, 0 lbs. maximum boost w/8.5 maximum Replacement for factory 75 HP 96 cu.in., 425 HP 427 cu.in., 45 HP 427 cu.in., 460 HP 454 cu.in. camshaft. Good low end and mid range torque and HP, fair idle, moderate performance usage, bracket racing, auto trans w/2000+ converter, cruise RPM, 0.5 to.5 Good mid range torque and HP, fair idle, moderate performance usage, bracket racing, auto trans w/2500+ converter, good w/plate or manifold nitrous system, cruise RPM, 0.75 to 2.0 compression ratio advised.

F-252/574-2S * RPM range shown is for average usage. These cam profiles will RPM higher, depending upon application. IMPORTANT NOTE: Gen V engines can use these camshafts and components if they are converted to adjustable rocker arms by machining the cylinder heads for /6 screw-in studs and 650- pushrod guideplates, and installing appropriate rocker arms. IMPORTANT: Adjustable Vacuum Advance Kits available. See page for details. NOTE: In order to use these cams in engines, you must groove the center of the rear cam bearing journal, /6 wide and 7/64 deep. 26 NOTE: Camshafts with SFO firing order ( , or 4/7 swap), are available on special order. Contact Crane s Performance Consultants for details. IMPORTANT NOTE: Some 97 thru cu.in. engines were equipped with exhaust valve rotators. In these instances when using dual valve springs, use either our Spring Seat Spacers or 4 of valve spring retainers (on the exhaust valves only) to prevent excessive valve spring shimming when eliminating the rotators. Some later engines were equipped with rotators on both the intake and exhaust valves. For these applications when using dual valve springs, use either 2 of our Spring Seat Spacers or CRANECAMS.COM our valve spring retainers to prevent excessive valve spring shimming when eliminating the rotators. Since 975, General Motors divisions have exchanged engines throughout different models. Be certain of exactly which engine you have before ordering.
