19. Rotate the engine 5-6 revolutions to seat the belt. Bring
the engine around to TDC as in step 5. Make sure the
cam sprockets are still aligned properly
(See Fig. 4)
.
20. Replace the middle timing cover. Torque bolts to 7 ft/lbs.
21. Coat the distributor o-ring with clean engine oil, and
install the distributor. Tighten mounting bolts to 17 ft/lbs.
(Note: The distribitor shaft and end of camshaft
are notched to elimiinate the possibility of
installing the distributor 180° out of time).
22. Before installing the valve cover, you will need to adjust
the valves. Set the no. 1 cylinder at TDC as explained in
step 5. Make sure the cam sprockets are aligned
properly
(See Fig. 4)
.
Using the tappet adjuster wrench,
adjust the valve lash on the no. 1 cylinder. The intake
valve clearances should be set at .006” and the exhaust
valve clearances at .008”. The feeler gauge should slide
between the rocker arm and the camshaft with a slight
amount of drag. Tighten the lock nut and re-check the
clearance. It should stay at .006” (intake) and .008”
(exhaust). Turn the crankshaft 180° counter-clockwise.
The cams should have rotated by 90°. Repeat the valve
adjustment on the no. 3 cylinder. Rotate the engine 180°
again, and repeat the adjustment on the no. 4 cylinder.
Rotate again by 180° and repeat the adjustment on the
no. 2 cylinder. The valves are now adjusted. After
adjusting the valves, re-torque the crankshaft bolt to 130
ft/lbs.
23. Thoroughly clean the valve cover mating surface, being
careful not to get any old silicone or dirt into the engine.
Clean off the rubber cap near the exhaust cam, put a thin
coat of automotive sensor safe silicone around it and
install it. Clean the groove in the valve cover and press
the valve cover gasket into the groove in the valve cover.
Apply a bit of automotive sensor safe silicone at the
corners of the gasket that go around the camshafts
(
See
Fig. 5).
Set the valve cover onto the cylinder head and
press down lightly to make sure the gasket is seated.
Install the four nuts and washers that go under the plug
wire cover and the four cap nuts and washers. Tighten
nuts to 7 ft/lbs
(
See Fig. 6 for torque sequence)
.
• Camshaft Run-In Procedure:
Edelbrock recommends performing a Run-In procedure
after installing new camshafts. Make sure the oil level in
the engine is at the proper level, and the oil is clean. We
recommend using a non-synthetic oil during the break in.
Start the vehicle and immediately bring the engine above
2500 rpm for at least 20 minutes. Vary the engine speed
constantly to help sling oil around the camshafts. After
the run-in, change the oil to remove any assembly lube.

24. Install the spark plugs and wires. Install the wire cover.
Tighten cap nuts to 7 ft/lbs. Connect the PCV hose and
the ground wire. Connect the negative battery cable.
