PowerMax Emissions cams also permit full function of stock engine control computers. Plus, they work great with aftermarket performance chips.

*Note: Firing Order 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 302ci and 351W engines with pedestal mounted rockers to have adjustable rocker arms without cylinder head removal or machining.
