12. Remove each plate carefully, keeping the intake cam
plate and exhaust plate in order, allowing the bolts to
remain in their positions in the plates. This will allow the
bolts to go back into their original positions and is an
easy way to keep them in order. Set the plates aside.
Carefully lift the cam caps off of the camshafts keeping
them in order. You will notice that each cap is marked
with an arrow and number that corresponds to its
location. The arrows point toward the timing belt, and
they are numbered with no. 1 being closest to the timing
belt and no. 5 being closest to the distributor. Make sure
to keep the bolts that hold the end cam caps in order as
well.
(
Note: You may need to pry the cam caps
loose before lifting them off. Carefully use a flat
blade screwdriver to pry the cam caps loose. See
Fig. 2).
There is an oil seal and dowel pin under the no.
3 cam cap. Inspect the oil seal and replace, if necessary.
13. Remove the camshafts one at a time, keeping them in
order.
(Note: The oil seals will come out with the
camshafts. Take care not to damage the oil seals).
Now is a good time to inspect the rubber cap near the
end of the exhaust cam, opposite the timing belt. If it is
in good condition, it may be re-used. Make sure the o-
ring sealing surface is clean and dry.
14. Remove the oil seals from the camshafts. If they are in
good condition, they may be re-used. Install the oil seals
onto the new Edelbrock Street/Strip Camshafts with the
spring side facing in towards the camshafts.
15. Apply a liberal coating of assembly lube to the journals
and lobes of the Edelbrock camshafts. Also, apply a
liberal coating of lube to the rocker arm contact surface
and to the journal suface in the cylinder head and on the
cam caps.
16. Set the camshafts into the head with the keyways facing
up. Apply some automotive sensor safe silicone to the
mating surfaces of the no. 1 and no. 5 cam caps
(See
Fig. 3)
.
Make sure the cam caps are in order and set
them down on top of the camshafts. Now install the cam
holder plates, and torque bolts #1 - 10 to 20 ft/lbs, and
bolts #11 - 14 to 7 ft/lbs
(See Fig. 1)
.
17. Install the back timing cover and gasket. Torque bolt to
7 ft/lbs. Install the cam sprockets, making sure to use
the cam keys. Hand tighten the cam sprocket bolts at
this time.
18. Slip the timing belt over the cam sprockets. Loosen the
belt tensioner adjusting bolt to allow it to tighten the belt.
Tighten the tensioner adjusting bolt to 40 ft/lbs. Tighten
the cam sprocket bolts to 40 ft/lbs. Make sure the cam
sprockets are aligned properly
(See Fig. 4)
. If you can
rotate the belt more than 90° by hand, the belt is too
loose. Make sure the tensioner is not stuck by loosening
the tensioner adjusting bolt and pulling up on the
tensioner with a hook or bent wire hanger, then re-
tighten the bolt. Replace the tensioner adjusting bolt
access plug.

Make sure sprockets are aligned
as shown. Stock sprocket “Up”
marks should point up with TDC
mark aligned as shown.
Carefully use a flat blade
screwdriver to lift cam caps.
DO NOT pry near the cam
journal surface. Wrap the end
of the screwdriver with tape
to protect the cam caps.
Apply
automotive
sensor safe
silicone to
the lightened
areas shown.
