Reinstall the original air injector check
valves by bolting them to the brackets
installed in step 20. The check valves should be
turned around so their outlet connections will
face toward the rear of the engine. See Figure
13. The left and right side check valves are still
used on their respective sides of the engine.
Re-connect the air inlet hoses to the (top fittings)
check valves.
NOTE: The check valve and manifold bolts may
have to be loosened to line up the right air inlet
hose. When hose is in place, retighten all bolts.
using the one inch I.d. hose provided, con-
nect the original check valve outlet con-
nections to the inline check valves on the Banks
exhaust manifolds. cut hose to lengths required
and secure using four no. 16 hose clamps provid-
ed. Make sure that the hose is routed away from
hot surfaces and sharp edges. See Figures 1 and
13.
reinstall the hot air tube between the air cleaner
inlet and the top of the right exhaust manifold,
2nd tube back from the front.
Reinstall spark plugs and tubes. Reattach
spark plug wires. Make sure wires are
attached to the proper spark plugs. engine firing
order is 1-8-4-3-6-5-7-2, with 1, 3, 5, and 7 on the
left (drivers) side, front to back, and 2, 4, 6, and
8 on the opposite side, front to back. Make sure
plug wire boots are pushed on firmly for good
electrical contact, and wires are routed as far
away as possible from manifold pipes to prevent
heat damage. If the condition of the spark plug
wires looks marginal, replace as required.
