NOTE: Many 1985-87 302 engines, all 88-97 302 passenger car
engines, all 96-00 302 truck engines, all 85-95 302 H.O.
engines, and all 94-97 351 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: Ford 221 thru 302 camshafts can be used in 351 Windsor
engines if the engine is changed to 221 thru 302 firing order
(1-5-4-2-6-3-7-8). Ford 351W firing order is 1-3-7-2-6-5-4-
8.

NOTE: In order to effect valve adjustment when using mechanical
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 99768-
16 positive locking nuts will permit valve adjustment.
NOTE: Crane offers a Pushrod Guideplate and Rocker Arm Stud
Conversion Kit (36655-16) for street applications, enabling
the 1977-00 302 cu.in. and 351W engines with pedestal
mounted rockers to have adjustable rocker arms without
cylinder head removal or machining. Refer to page 325 for
details.
NOTE: Some engines have long valve stems which will result in excessive
valve spring assembly height. Different springs and
retainers may be required to prevent excessive shimming.
Contact Crane’s Performance consultants for details.

NOTE: Many 1972 and later Ford-Mercury V-8 engines are
originally equipped with a retarded crankshaft sprocket.
This may cause idling and performance problems when
installing aftermarket camshafts. We recommend using our
44975-1 or 44984-1 timing chain and assemblies, a pre-
1972 crankshaft sprocket, or degreeing in your camshaft.
The non-retarded sprocket will have the alignment dot and
keyway slot directly in line with each other.
NOTE: Left hand rotation mechanical camshafts are available on
special order. Contact Crane’s Performance Consultants for
details.
