only; install the push
rods with the ball ends in the tappets. When using
Tool C-3695 (Fig. 69), rocker arm valve spring com-
pressor, to position large end of push rod under rock-
er arm,
make certain the low point of the camshaft is
under the tappet.
Install new intake manifold gaskets
and seals.
(7) On
273, 361, 383 and 426 Cubic Inch Engines
install the small end of the push rods in the tappets.
Use alignment rod on Models 361, 383 and 426 as
shown in Figure 70 to assist in aligning the push rods.
(8) Install the rocker arm and shaft assembly start-
ing each push rod into its respective rocker arm socket
making sure to install the long stamped steel retain-
ers in the number two and four positions.
(9) On
361, 383 and 426 Cubic Inch Engines Use
extreme care in tightening bolts to 25 foot-pounds
torque so the tappets have time to bleed down to their
operating length. Bulged tappet bodies, bent push
rods, and permanently noisy operation may result if
tappets are forced down too rapidly.
a. Install tappet chamber cover and tighten end
bolts to 9 foot-pounds torque.
b. Install the valve covers with new gaskets and
tighten to 40 inch-pounds torque.
(10) On
273 and 318 Cubic Inch Engines
coat the
intake manifold gaskets and side seals with number
1316241 sealer.
(a) On
273 Cubic Inch Engine
install the intake
manifold gaskets with the bead down and the end
seals locked in the tangs of the head gasket.
(b) On
318 Cubic Inch Engine
install the intake
manifold gaskets with the bead down and the end
seals locked in the tangs of the head gasket.
(c) Add a drop of sealer in the
"V"
notches of the
side seals after installation.
(11) (a) On
273 Cubic Inch Engine
position the
in-
take manifold on the engine and install the twelve
attaching cap screws "Finger Tight" in the tighten-
ing sequence shown in Figure 71. Tighten the cap
screws one through four to 60 inch-pounds and tight-
en the remaining cap screws to 60 inch-pounds, then
retighten cap screws one through four to
270
inch-
pounds and follow by retightening the remaining cap
screws to 270 inch-pounds in the sequence shown.
(b) On
318, 361, 383 and 426 Cubic Inch Engines
install the intake manifold, tighten manifold bolts to
40 foot-pounds torque for 318 cubic inch engine and
50
foot-pounds torque for 361, 383, 413 and 426 cubic
inch engines.
