BRACKETS:
1.
Some vehicles will require a throttle bracket extention plate to move the stock throttle bracket forward. This extention is available as
Edelbrock #8034
(See Fig. 1)
.
2.
Vehicles with automatic transmissions will require using a kickdown stud on the throttle lever to operate the transmission kickdown rod.
The supplied kickdown stud fits directly to the lower hole on the throttle lever of Performer and Thunder series carburetors
(See Fig. 2)
.
3.
Remove the lifter valley heat shield from your stock manifold and install it on your new Edelbrock manifold using the suppliied drive
screws
(See Fig. 3)
.
NOTE:
This step must be performed!
•
PCV VALVE:
Some engines use a PCV valve that is clamped to a hose between the carburetor and the intake manifold. The stock AMC
manifold has a 3/8” pipe port at the intake manifold, rather than a hole to accept a rubber grommet, which the Edelbrock intake manifold
uses. To reinstall the PCV valve to our manifold, you may purchase a grommet from your local NAPA dealer (Part #630-1411), and 10” of 3/8”
vacuum hose
(See Fig. 4)

PREP AND TUNING FOR POWER:
1.
Generally speaking, the stock jetting for a Performer Series or
Thunder Series carburetor will not need changing.
Specific
applications may show an increase in power by tuning the fuel
mixture.
2.
Aftermarket distributor curve kits may be used with Torker intake
manifolds. A basic ignition curve of 12° to 14° initial and a total of
36° to 38° advance is a good starting point.
3.
Use modified or high performance cylinder heads such as our
Performer RPM, and port-match the manifold to the heads.
4.
The compression ratio should be at least 9.5 to 1 to work properly
with most camshafts that are designed to operate in the 2500-6500
rpm range.
5.
Installation of aftermarket headers, camshafts or both with an
Edelbrock Torker series manifold may lean carburetor calibration.
Should this condition occur, recalibrate with a richer jet.
•
CAMSHAFT AND HEADERS:
Torker manifolds are compatible with
aftermarket camshafts and headers.
Header primary tube diameter
should be 1-5/8” to 1-3/4” depending on the specific engine combination.
Camshaft being used should be designed to operate within the same RPM
range as the Torker intake manifold.
