*Note: Firing Order 1-5-4-2-6-3-7-8, Ford 221 thru 302 camshafts can be used in 351 Windsor engines if the engine is changed to 221 thru 302 firing order (Ford 351W firing order is 1-3-7-2-6-5-4-8).**Note: Many 1985-87 302ci engines, all 1988-97 302ci passenger car engines, all 1996-00 302ci truck engines, all 1985-95 302ci H.O. engines, and all 1994-97 351ci 'Windsor' engines are equipped with hydraulic roller camshafts and lifters. Conventional hydraulic, mechanical, or roller lifters can be easily installed in these engines, providing the appropriate kit components are used.
***Note: To provide the most accurate valve adjustment on hydraulic lifter camshafts, the heads must be machined to accept screw-in studs (on engines not originally equipped). On engines equipped with bottleneck type studs, using 270-99768-16 positive locking nuts will permit valve adjustment. For engines equipped with pedestal mounted rocker arms and hydraulic lifters, excessive lifter preload can be easily remedied by using Crane's rocker arm pedestal shim kit 270-99170-1. Crane offers a pushrod guideplate and rocker arm stud conversion kit 270-36655-16 for street applications, enabling the 1977-00 255 and 302ci engines with pedestal mounted rockers to have adjustable rocker arms without cylinder head removal or machining.

- Available alone or with lifters, the Energizer Series of performance hydraulic camshafts offers streetable performance with serious torque, horsepower, and RPM gains at an affordable price. These single-pattern camshafts have profiles with tighter lobe separations for added torque, midrange power, and throttle response. They're great for stock or mildly modified V8 applications (not for computer-controlled engines).
