CARBURETOR INSTALLATION
1. Remove rag from intake manifold and install new studs, mounting
gasket and adapters (where applicable).
NOTE: Do not use any cement, glue, or RTV sealant on
gasket.
2. Carefully place new carburetor on gasket.
3. Replace all mounting nuts and washers. EnduraShine™ finish
carburetors should use the supplied 5/16" flat washers under any
other washers used. Hand tighten with a short box end wrench,
alternating between diagonally opposed nuts.
CAUTION: Overtightening may break carb base and void
warranty.
4. Connect all throttle and transmission linkages and throttle return
springs. You may have to cut, bend or modify your stock throttle
cable brackets to fit the new carburetor, or use GM #352279 (See
Fig. 8) . 1972-78 small-block Chevy V8s may use Edelbrock
Throttle, Transmission, and Cruise Control bracket #8030, #8031,
#8032, or #8036 (chrome).
IMPORTANT NOTE: With engine off, make sure that there is
no interference when opening and closing the throttle. Be
sure there is no binding or hanging up between idle and
wide open throttle as this could cause the throttle to stick
open, resulting in loss of engine speed control.
GM#352279
5. Connect manual choke cable to the provided lever attachment point
and cable mounting bracket (manual choke models) (See Fig. 9) .
Electric choke models connect red choke wire to 12 volt (+) source
that is activated by ignition switch (Not coil or alternator, see
Fig. 7) .
NOTE: If manual choke is not connected (secondary carb of
dual carb set-up, for example), then choke blade must be
fixed open. To lock open, use a stiff piece of wire between
the choke lever and the mounting bracket. Fold the wire to
double its thickness about one inch from one end. Insert the
wire in the choke lever, hold choke blade in the wide open
position, and tighten cable clamp on folded end of wire.

6. Connect all vacuum hoses to their proper location on carburetor
(See Fig. 1) . Replace hoses that appear brittle or cracked to
prevent vacuum leaks.
7. Connect fuel line to carburetor. Avoid contact with any sharp edges
or areas of extreme heat.
8. Edelbrock idle compensator #8059 may be installed to raise idle
speed during air conditioning compressor operation.
9. Install new air horn gasket and air cleaner stud (supplied). Install
air cleaner making sure it does not contact linkage or fuel line and
has proper hood clearance. We recommend Edelbrock Pro-Flo
chrome air cleaner #1221, which is a 14" diameter open element
air cleaner that is designed to fit all Edelbrock Thunder Series
carburetors. Extremely low profile air cleaners will not fit electric
choke carburetor without air cleaner spacer #8092 (due to choke
and fuel line interference) but will fit manual choke carburetor when

NOTE: Some late model Ford 460 engines are equipped
with hot fuel bypass units. It is necessary to replace the
stock unit with Ford #E3TZ9N176B (with blue dot) which has
a 0.040" orifice.
