RPM range shown is for average usage. These cam profiles<br />
will RPM higher, depending upon application.<br />
IMPORTANT: Adjustable Vacuum Advance Kit available. See page<br />
333 for details.<br />
IMPORTANT: Check your hydraulic lifter preload, with your original<br />
pushrods, to first determine if different pushrods may be<br />
required. On 72-97 engines, if your hydraulic lifter preload is<br />
excessive, this can be remedied by using <strong>Crane</strong>’s Rocker Arm<br />
Pedestal Shim Kit (99170-1). Refer to page 324 for details.<br />
IMPORTANT: <strong>Crane</strong> offers Pushrod Guideplate and Rocker Arm<br />
Stud Conversion Kits, (35655-16 and 52655-16) for street<br />
applications, enabling the 370-429-460 cu.in. engines with<br />
pedestal mounted rockers to have adjustable rocker arms<br />
without cylinder head removal or machining. See page 325<br />
for details.<br />

NOTE: To provide the most accurate valve adjustment on hydraulic<br />
lifter camshafts, in other than 429 Super C.J. engines, a<br />
method of effecting valve adjustment is required. On 68-71<br />
engines equipped with bottleneck type studs, using 99768-<br />
16 positive locking nuts will permit valve adjustment. On<br />
72-97 engines, the heads must be machined to use 99159-<br />
16 screw-in studs and pushrod guideplates.<br />
NOTE: Special length pushrods can be ordered to provide proper<br />
hydraulic lifter preload. Refer to page 305 for special<br />
pushrod ordering instructions, and page 374 for checking<br />
your hydraulic lifter preload.<br />

NOTE: Many 1972 and later Ford-Mercury V-8 engines are<br />
originally equipped with a retarded crankshaft sprocket. This<br />
may cause idling and performance problems when installing<br />
aftermarket camshafts. We recommend using our 35975-1<br />
timing chain and gear set, a pre-1972 crankshaft sprocket,<br />
or by degreeing in your camshaft. The non-retarded sprocket<br />
will have the alignment dot and keyway slot directly in line<br />
with each other.<br />
NOTE: These camshafts also fit the 1969-70 Ford 429 Boss Hemi<br />
V-8 engines. Some kit components will differ. Contact<br />
<strong>Crane</strong>’s Performance Consultants for details.
