INSTALLATION INSTRUCTIONS
®
PLEASE study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and
procedures. However, you should be familiar with and comfortable working on your vehicle. If you do not feel comfortable performing this installation,
it is recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at:
1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday or e-mail us at [email protected].
IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation
will void your warranty and may result in poor performance and engine or vehicle damage.
DESCRIPTION: This intake manifold is designed to allow the use of a carburetor on a Ford 4.6L Modular Single Overhead Cam engine. This will
eliminate the use of the OEM fuel injection system and is intended for longblocks that have been installed in early model or custom vehicles. It is also
intended for use in racing classes where fuel injection is not allowed or is not desirable. The #2839 includes an electronic Timing Control Module,
which picks up MAP, Crank Position, and Cam Position, and drives the stock Coil-on-Plug system. The Timing Control Module comes loaded with a
basic timing curve and rev limit, both of which can be easily modified using a laptop and the included Pro-Data software. The #2838 does not include
the electronics, but they may be purchased seperately as part #91237.

NOTE:
This intake manifold is not designed for use in vehicles equipped with the 4.6L engine from the factory. It is only intended to be used on engines
that have been swapped into a custom application where modifications can be made as necessary. These installation instructions do not attempt to
cover the steps necessary to convert a fuel injected vehicle to carburetion, they only cover what is needed to install this intake and the related
electronics on a properly prepared longblock.
MANIFOLD INSTALLATION:
1. Use only the recommended OEM intake gaskets with this manifold.
2. Fully clean the intake manifold and cylinder head flanges, as well as
the end seal surfaces of the engine block. No sealants or adhesives
are necessary.
3. Install the manifold on the block. Lightly coat the manifold bolts with
30W motor oil then gently thread them into the heads to hold the
intake in place. Do not apply any torque to the bolts at this time.
4. Install the themostat and allow it to drop into the machined recess.
The o-ring supplied with the thermostat should then be pressed in
and compressed by the thermostat housing.
5. The manifold bolts (including the thermostat housing bolts) can now
be tightened according to the torque sequence
(See Figure 1).

1. Using the hardware supplied with the Timing Control Module, mount
the unit in a suitable location inside the engine compartment, such
as the firewall, or inner fender. Mount the module so that the main
harness can be easily connected. Bear in mind that the shorter side
of the coil pack wires will be routed to the passenger side bank.
2. Route the harness from the control module to the passenger side of
the engine, towards the front. Locate the Crankshaft Position
Sensor connector. It is a two wire connector with red and black
wires at the end of a long section of harness which is encased in a
smooth, rubberized, dark grey heatshield. Route this line down the
passenger side of the engine, and connect it to the Crankshaft
Position Sensor. The Crankshaft Position Sensor is located on the
front of the passenger side of the engine, just above the oil pan rail.
3. Locate the MAP Sensor connector. It is the three wire connector
with orange, green, and brown wires. Connect this to the MAP
Sensor on the rear of the manifold.
4. Locate the Camshaft Position Sensor connector. It is a two wire
connector with tan and brown wires extending from a length of
rubberized heatshield. Route this wire along the driver side of the
intake manifold and down the front of the block. Connect the wire
to the Camshaft Position Sensor, located at the front driver side of
the block, just below the valve cover rail.
Figure 4 - Assembly Mounting
MAP SENSOR INSTALLATION:
1. Apply a bit of liquid Teflon thread sealant to the threads of the
supplied 1/8” NPT to 1/4” hose fitting and install the fitting into the
1/8” NPT hole in the intake manifold plenum
(See Figure 2) .
2. Attach the MAP sensor to the supplied bracket (See Figure 3) .
3. Install the sensor/bracket assembly on the intake manifold using the
throttle cable bracket bolt hole bosses
(See Figure 4) . If using a
Ford throttle cable bracket, install the sensor assembly on top of the
bracket.
4. Connect the sensor to the fitting with the supplied hose.
Figure 2 - Map Sensor Fitting
Figure 3 - Sensor/Bracket Assembly
5. Attach the wire connectors to the coil pack associated with the
attached cylinder number. The shorter coil wire set will be routed to
the passenger side bank, while the longer wire set will be routed
along the driver side bank. The connector on the end of the harness
will go to the cylinder closest to the front of the engine and the rest
of the connectors should line up with their respective coils.
6. Locate the portion of the harness with the gray, four wire connector
extending from the coil pack wire set. The ring tab is a ground and
should be mounted to an unpainted area of the block or frame. The
two wire plug that also extends from the gray connector will be cut
off, and the red wire should be routed to a switched (only has power
when the key is on) 12 volt power source. The yellow and brown
wire will not be used and should be taped off to prevent a short.
7. The loose yellow wire that extends directly out of the main harness
plug is the tachometer lead. This wire should be taped off and
secured if you are not using a tach. The pink and blue wires will
attach to a two-step timing retard box if you are using one,
otherwise they should be taped off and secured, as well.

CARBURETOR RECOMMENDATIONS: Manifold will accept any standard square bore flange carburetor, including all Edelbrock Thunder AVS and
Performer models. Due to engine efficiency and runner design, we recommend the use of a 600 cfm or larger carburetor. Dyno testing was
conducted with our 750 cfm high performance carburetor (part #1407). The best results were achieved with the stock primary jet, .075” x .047”
metering rods (part #1459), and .100” secondary jets (part #1428). We recommend using the stock calibration to establish a baseline, and tuning
accordingly from there. A smaller carburetor, such as the Thunder AVS 650 cfm (part #1806), would be preferable for street use particularly if the
stock camshaft will be reused.
CAMSHAFT AND HEADERS: Edelbrock does not currently make a camshaft for this engine. Although the stock cam can be used, we recommend
a more aggressive grind that will take full advantage of the improved runner design and flow capacity. Headers are not strictly necessary, but their
use is strongly recommend. Primary tube diameter should be no less than 1-5/8” with a 3” collector.
THROTTLE AND ACCESSORY BRACKETS: Throttle and kickdown brackets on some vehicles may require modification to fit. A universal throttle
cable bracket is also available under the Russell brand name (part #611069).
DISTRIBUTOR: The Ford 4.6L Modular engine uses a direct fire Coil-On-Plug ignition distributorless ignition system. A standalone ignition control
module is available seperately (#91237) and is included with the #2839 version of this manifold. Please refer to the seperate instruction sheet for
specific installation and tuning recommendations.
