DESCRIPTION: Edelbrock Victor X intake manifolds are designed to optimize horsepower gains for Honda race engines when operating in the
7,000 to 10,000+ rpm range. Specific applications are listed below. These manifolds feature five-inch long, tapered runners and a large, round
plenum for optimal airflow on both all motor, and forced-induction applications. The 66mm machine-profiled throttle body opening fits oversized
throttle bodies without grinding. Victor X manifolds will accept either a GSR or a standard idle air motor, and include Civic / Integra Type R throttle
cable bracket bosses. Model numbers 4760, 4764, and 4767 include four extra fuel injector bosses, which must be machined to add a secondary
fuel system. The 4761, 4765, and 4768 include already machined secondary fuel injector bosses and a machined fuel rail.
NOTE: Victor X manifolds move the throttle body by several inches. The air inlet system you are using may require modification.

degrees to clear the intake (See Fig. 3).
Special Instructions for #4760/4761: In some cases, the idle
air control motor (IAC) wire harness will no longer reach the
solenoid. Use the supplied wires and connectors supplied in kit
to extend the factory wire harness.
10. Install air inlet (Some air inlet systems may require modification).
11. Check all fluid levels, start engine and check for possible vacuum
leaks.
12. This is a race manifold with different flow characteristics than
your stock manifold, modifications to your fuel curve and cam
timing will be necessary for optimal performance.

SPECIAL INSTRUCTIONS FOR 4761, 4765, AND 4768
NOTE: Basic manifold installation is the same as manifolds without a fuel rail. Install fuel rail before continuing with the remainder of the
installation. Manifolds are designed to be used with either the Pico style injector or the Bosch style injector. Refer to Figure 4 during the fuel rail
installation process.
Pico-Style Injectors: When using Pico-style injectors, attach fuel rail directly to intake location “A” using the two 1/4-20 x1-1/8” hex-
head screws supplied in kit.
Bosch-Style Injectors: When using Bosch-style injectors, attach bracket “B” to the fuel rail with the supplied 1/4-20 x 3/4” Allen-head
screws. Next, attach the fuel rail to the intake manifold using the two 1/4-20 x 1-1/8” screws and 1/4” lockwashers as shown.
