§  DESCRIPTION:  The Edelbrock Victor EFI intake manifold is designed for ultra high performance and racing 351W 

based engines.  Its large short runners are compatible with stroker applications up to 427 C.I.  There are no provisions for 
EGR or the PCV system.  The fuel injector angles and hold-down posts are positioned to work with stock Mustang 5.0l 
left and right fuel rails or aftermarket equivalents (aftermarket fuel rails and an adjustable regulator are recommended for 
high {400+} horsepower applications).  Push-Lok fuel line has been included to make longer fuel rail crossovers.   

 
§  POWER PACKAGE:  This manifold is designed for use with either our Victor Jr. (PN 7716) or Victor (PN 7721) cylinder 

heads. The manifold port exits are sized to fit within the Fel-Pro 1262 gasket.  We recommend our 75mm Throttle Body 
PN 3826.   

 
§  ACCESSORIES:  Edelbrock offers a full line of chrome and Elite Series Valve covers for SB Ford engines.  We also have 

water pumps that will increase coolant flow and block pressure in your engine.  There are three different models for SB 
Fords.  See our catalog for details.  To order a catalog, call (800) FUN-TEAM. 
 

§  EGR SYSTEMS:  This manifold is intended for non-emission, non-EGR, racing applications.  Because the EGR plate is 

not used the throttle body is relocated.  A new throttle cable bracket is included with this kit. 

  

 

 

1)  To use standard Mustang 5.0l fuel rails: Cut and remove the stock crossover tubes.  Assemble the fuel rails onto the 

manifold.  Lubricate one end of  the supplied Push-Lok hose with a small amount of lubricant (silicon, spray lube or 
white grease).  Push the hose over the barbs until it stops against the collar.  No clamp is necessary.  Now determine 
the length necessary to reach the opposite rail, cut the hose, lubricate and install.  The front crossover tube requires 
more planning because of the close proximity of the manifold, the fuel rail ends, and the distributor.  We suggest you 
fit it on the engine.   

2)  We recommend the Fel-Pro Printoseal #1262 intake gasket.  For best results, port match the manifold to your heads. 
3)  Fully clean all traces of old gasket material and sealant from all of sealing surfaces. Apply Edelbrock Gasgacinch to 

both the head intake flange and back of gasket.  Let dry and install gasket to head. 

4)  Do not use cork or rubber end seals.  Use “sensor safe” silicone sealer instead.  Apply a ¼” high bead across each 

block end seal surface, overlapping the intake gasket at the four corners.  This method will eliminate end seal 
slippage and deterioration.  

4)  For ease of installation and a cleaner look, we recommend using Edelbrock Manifold Bolt and Washer Kit #8524. 
5)  The Edelbrock throttle bracket substitutes for the stock EGR plate and throttle bracket.  Place it underneath the two 

right rear manifold bolts (# 3 & #7 in Figure 1).  Some valve covers require the throttle bracket to be trimmed or 
spaced up to fit. 

6)  Manifold Torque:  See Figure 1.  On early model iron heads, there is no support underneath manifold boltholes 

circled 5, 6, 7, and  8.  These bolts need to be hand-tightened with a short box end wrench being very careful not to 
damage the manifold.  Torque all other bolts in the sequence to 15-18 ft-lbs. 

7)  The stock Mustang heater tube assembly will interfere with the Victor EFI throttle bracket and cable arrangement.  If 

a heater unit is required, re-route your heater lines with hoses and eliminate the metal tubes.
