Copyright 2020 by AUTOSALES, INCORPORATED The jet fittings are color-coded for use with nitrous (blue) and fuel (red). If you can’t see the belt part number then the engine might need to be rotated over so the number is visible. This manifold pulls through 7000 rpm, but it's divided plenum also makes it work at low rpm. The meter should read between 40-50 ohms with the Ultra-Spark 50 wires per foot and about 500 ohms per foot with the Ultra-Spark 500 sparkplug wires. Apply assembly lube to both ends of the fuel pump pushrod, if applicable. Double check valve adjustment. Edelbrock 60255 - Edelbrock Performer RPM Cylinder Heads Cylinder Head, Performer RPM, Aluminum, Assembled, 60cc Chamber, 190cc Intake Runner, Ford, 289, 302… Below are some instructions on how to install the universal spark plug wires. First you need to verify the bottle pressure is between 900-950 p.s.i. Edelbrock cylinder heads are manufactured in the USA using state-of-the-art port designs and combustion chamber shapes to maximize performance. Cylinder Head, Performer RPM, Aluminum, Assembled, 72cc Chamber, 170cc Intake Runner, Ford, FE. For example, if the OEM states that 45 psi is an acceptable fuel pressure for a given vehicle, the fuel pressure drop seen when the nitrous system is activated should be no more than 2.7 psi on EFI-equipped vehicles. Also, we recommend that you do not use platinum plugs. If there is fuel in the float replace float. It is best to use a non-projected type plug. 502 B/B Chevy • 1996 & Later Gen V & VI, LS1 engines • 1997-04 w/Timing Control Module, LS2 engines • 1997-04 w/o Timing Control Module, 496-555 B/B Chevy • 1965-95 Mark IV & V, 496-555 B/B Chevy • 1996 & Later Gen VI w/Rectangle Port Cylinder Heads, 496-555 B/B Chevy • 1965-95 Mark IV & V w/Rectangle Port Cylinder Heads, 340-418 S/B Chrysler • 1967-91 w/Flat tappet cam, 383 B/B Chrysler • 1968-79 w/Flat tappet cam, 440 B/B Chrysler • 1968-79 w/Flat tappet cam, 289-302 S/B Ford • 1981 & earlier w/Flat tappet cam.

This is a Lean-Best Idle Set. Double check spark plug gap, the gap should be between .025” & .035”, if the spark plug gap is too great then the spark could blow out due to the higher cylinder pressures. Use a terminal crimping tool to secure the terminal on the wire. For emissions legality and to maintain the free powertrain warranty (if applicable) the supercharger kit CANNOT be modified from its originally supplied configuration. With a Edelbrock wet plate system there is no need to recalibrate the carburetor. Ideally a gap between .025" and .035" should be used on high horsepower applications where an inductive style ignition system is utilized. In most all other cases, the restrictors should be used, one of the only times the restrictors would not be used is if the application is always driven in cold freezing weather. The embossed bead of the intake gaskets should face up towards the intake manifold. Projected plugs allow a greater portion of the electrode to be exposed to combustion gases and possibly cause pre-ignition. In the process we are losing torque and horsepower. The casting’s computer-designed internal passages and precision powdered metal impeller produce the maximum flow rate possible. Reading should be infinite (No continuity). Double check all your pulley alignment if the supercharger pulley is slightly off, then in some cases the supercharger bolts need to be loosened that secure the unit to the heads and shift the supercharger forward or back to get better alignment. With water necks that use a gasket, coat both sides of the water neck gasket with silicone. Edelbrock offers intake manifolds with matching camshafts to help eliminate the guess work. A cat-back exhaust system is acceptable with the supplied calibration. If there is no shield/baffle, then one will need to be installed to resolve this problem. When the button is released you will be in the options menu. Purchase any used aftermarket manifold for the 302 that is designed to function in the 3,500 to 6,500 power band. Edelbrock does not recommend the use of cork or rubber end seals, we recommend a ¼” bead of silicone to be used in place of the end seals. Worked very well. If coolant is dripping continuously from the Edelbrock water pump weep hole, then the water pump seal is bad. If there is a short in the ground this could be the cause. Apply assembly lube to the cam face of the lifter and side body. Now, that's all changed with the Performer RPM head for 351-C. Within a few minutes gaskets and surface will become tacky to the touch. Instead, only cut about half way through the insulator, then twist and pull the end off. The pulley can be changed but Edelbrock will NOT supply a supporting calibration. The Supplied calibration will not be compatible with any other aftermarket components from the catalytic converters FORWARD. The use of restrictors is not required but are recommended for warmer climates. Be sure the intake clears the valve cover rails; some applications will require to put a 45° break at the top of the intake flange for valve cover rail break back clearance. If the bottle must be mounted parallel to the axles of the vehicle (sideways), the valve handle and label must be angled at approximately 45 degrees toward the front of the vehicle. This adapter bushing is supplied with the Fan Clutch. Disconnect sensor from harness. If the sealing surface is leaking, the intake manifold will need to come off. Trending at $999.99. Designed to work with the 351-C, 351-M, and 400-M, they feature very streetable 190cc intake runners with 2.05"" intake and 1.60"" exhaust valves that provide more than enough volume for outstanding power … The plate injects both nitrous and additional fuel using one nitrous spray bar and one fuel spray bar. Also keep in mind that retarding too much timing will also hurt you. Once the desired frequency has been set press the FUNCTION button to go back around to EXIT and then press ENTER. No other parts are required to install an Edelbrock street supercharger kit. A dedicated fuel system consists of a fuel pump, fuel pressure regulator and feed line to the fuel solenoid. There are a couple steps to ensure you get your intake gaskets sealed up properly, below we will go over the steps. Disconnect sensor from harness. There are a lot of variables that can affect boost numbers like elevation, temperature, humidity and engine modifications. Additional fuel is added along with the nitrous to maintain a stoichiometric air/fuel ratio. It has exhaust heat passages, but no EGR provisions or divorced choke stove pad. They will restore to A. In the event of a coolant leak this will simplify determining whether the engine or intercoolers system is leaking. Use caution when tightening up NPT fittings, they have tapered threads and if over tightened can crack the intake manifold. If this method is not used you may see a pressure drop when the fuel is flowing through the plate during the use of the nitrous system. It’s also good practice to top off the bottle when it reaches a volume of less than 40%. Edelbrock Heads: E-Street Ford Cylinder Heads This made-in-the-USA head is Edelbrock's value leader. Now compare that measurement to the hub height listed in the Edelbrock water pump section. If the pump is rotating counterclockwise you need a reverse rotation water pump. A full bottle can vary from 750 to 1200 psi depending of the method used to fill the bottle. Some Edelbrock racing water pumps use AN style fitting and do not require any sealant on the threads for the auxiliary fittings, they seal up with an O-ring. These heads balance high rpm flow with a wide torque band, providing power from 1,500 to 6,500 rpm. Carefully trim each IMS to again get the maximum idle RPM. Apply assembly lube to the distributor gear. Head gasket re-torqueing is not required but recommended. The results will provide anyone considering a 351C, Clevor, or 351M/400 build, new information to consider when deciding on a stock, ported, modified, or aftermarket Cleveland head. The use of methanol injection will void the supercharger and the powertrain warranty if eligible. If you chose to install the cold air intake system a custom tune will be needed, and not available through Edelbrock. Some Edelbrock intake manifolds use special length intake bolts due to the intake manifold design. Edelbrock Carburetor Linkage Adapters, Studs & Cable Extensions for all of your carburetor connection needs. Ultra-Spark 50 spark plug wires are engineered for high performance engines that need all of the voltage they can get for maximum power output. To enter the options menu, hold down the ENTER button after turning on the unit. The tune for the street supercharger kit is not compatible with a cold air intake system. Controllers with build date 05/07 and later. For most performance vehicles, you should replace your spark plugs every 30,000 miles. Install the fittings and injectors onto the fuel rails and secure the fuel rails to the manifold using the supplied hardware. This will prevent any air and/or fuel leaks. Be sure your running the correct valve spring pressures and the springs can handle the camshaft lift. Turn on the dedicated pump and monitor the fuel pressure as it flows through the gauge. If you have an end seal leak, the intake manifold will need to be removed, inspected, cleaned and reinstalled. TIP: It is not necessary to cut completely through the insulator in order to strip the wire. You should never have big jumps in the Fuel or Spark modifiers from one location to the next. We used 6 to 6.5 psi of fuel pressure to perform our jet map testing on this system. All of the performance results below are real results from engine dynamometer tests on factory short blocks. Re-open your hood to see compressed clay so you can measure it to check for hood clearance. The inlet and outlet must be clocked together, cannot be clocked independent from one another. Yes, there are racers that use different pressures, but the testing we did here at Edelbrock to ensure the jetting maps within this manual are correct, was done in this pressure range. This wide power band makes them perfect for propelling speed boats. First be sure cam was broken-in properly. If silicone was used, then more than likely the surfaces were not cleaned properly. If you do not have at least 6 psi of fuel pressure going to the fuel solenoid, when it is activated, you will be lean. #15407: Compact, 16” x 16”, Universal Fit. With the ignition off, disconnect collant temp sensor & ECU from harness. Coat head surface and cylinder head side of intake gaskets with 2 coats letting dry between coats Edelbrock Gasgacinch #9300. Next check all fuel filters and fuel delivery. A dedicated fuel system offers a greater degree of tune-ability and eliminates problems that might arise from sharing a fuel pump with the engine. Be sure the rocker arms are not hitting the valve covers or valve spring retainer. Check float level, the float level should measure 7/16”. Will not work with pressed in studs unless the rocker arm studs are pinned/or studded. It should make good power, and it did just okay with a Holley 4150 I had on it. In other words, accelerated combustion occurs. U.S.P. The booster pump allows the factory pump to provide its maximum volume capacity; the booster pump then increases the fuel pressure. The purpose of a dedicated fuel system is to provide fuel enrichment for the nitrous system independent of the primary fuel system. Closed loop control does not work at Idle. All Edelbrock nitrous systems are tuned utilizing liquid nitrous, which is denser than gaseous nitrous as well as more stable. We advise lowering the heat range of your spark plugs 1 step for every 100 hp added with nitrous. Learn more. All of this positioning information is critical to system operation. The only change that can be made from stock would be a cat back system with the Edelbrock street supercharger tune. Tighten the adjustment screw locking nut. The Edelbrock intake manifolds are made of aluminum and the 5/16” carb flange holes are not Heli-coiled. Get the front end of the vehicle up in the air using some wheel ramps. VICTOR TOP END KITS deliver the ultimate in high performance for street/strip applications. Edelbrock recommends stock ratio rocker arms to be used with Edelbrock top end kits. The balance of the assembly depends primarily upon the concentricity of the fan clutch with the pump shaft. Coat all the lobes and bearing surfaces with assembly lube. EFI Top End Kit for S/B Chevy • 1957-86. This can also cause fuel leaks through the airhorn gasket. A possible bad connector, if so replace connector. Some Edelbrock intake manifolds require the use of a #2732 spacer. A crack around the fitting would be due to a fitting being over tightened. if ordered today, Cylinder Head, E-Tec, Aluminum, Assembled, 64cc Chamber, 170cc Intake Runner, Chevy, 302, 327, 350, 400, Each. If this is not done, then oil/coolant will ladder up the intake bolt threads and puddle on the intake manifold. With the ohm meter connected to both ends of the sparkplug wires, the meter should read between 40-50 ohms with the Ultra-Spark 50 wires per foot and about 500 ohms per foot with the Ultra-Spark 500 sparkplug wires. Be sure the timing chain/camshaft was installed correctly. The Purge Valve Kit is designed to vent gaseous nitrous to the atmosphere to fill the nitrous feed line with liquid nitrous for a better nitrous charge when the nitrous system is in use. U.S.P. There is no requirement to use a high flow thermostat with an Edelbrock water pump. Check your carburetor calibration and operation. If you have the old water pump measure from the sealing surface to the hub where the fan would mount too. Go to spark Modifiers and find the RPM and VAC setting closest to your current Idle and VAC readings. If you don’t have clay handy you can do the same thing by balling up some foil balls. The supercharger unit will have to come off the engine to perform the oil change. This is not the case as the Venturi boosters are also different and Edelbrock does not sell Venturi boosters separately. Many people feel that if a bottle is full then the pressure must be right, however, that isn’t always true. Edelbrock does not offer a non-siphon tube bottle for automotive use. Another problem with a higher ratio rocker arm is the added load on the camshaft lobe. A faulty sensor could also cause this. Readjust idle speed with blade adjustment screw to desired idle. Fully warm engine and ensure choke is fully open. Estimated International Ship Date: Only use the Idle fuel and spark settings once you have the regular Fuel and Spark Modifiers where the engine runs the best. If you find a short in the ground wire replace harness. Would recommend using some silicone on the first couple threads of the intake manifold bolts before they are installed. Then place a 7/16” drill bit between the airhorn gasket and the top of the outer end of the float just past the inboard float radius. No, our stage one and some stage two supercharger systems are designed and tested on completely stock vehicles. At 950 psi nitrous has a density of 5.44 lb/gal., bottle pressure is more stable and can easily be sustained with the use of a bottle heater. Be sure self-aligning rocker arms are not being used with guide plates. Spark Plug Wires and Coil Mounting Hardware. Check float level, the float level should measure 7/16”. Doing this will work the air pockets out of the cooling system. First, it’s very important to be sure all mating surfaces are clean. Check the all fittings and injectors for any leaks. No, a standard 50/50 blended coolant is all that is needed for the intercooler system. It is important to understand how the bottle valve and siphon tube are assembled to properly orient the bottle in your vehicle and ensure that it picks up liquid nitrous while undergoing acceleration. Edelbrock 400 HP Performer RPM Top End Engine Kit for 351W Engines. If the cam lobes are going flat this can also create a backfire. dba Summit Racing Equipment | Trademarks. Installing an aftermarket power adder like an Edelbrock supercharger will normally void your powertrain warranty. Add Photo (50) Comp Cams Stage 3 Xtreme Energy 234/238 Hydraulic Roller Camshafts (96-04 GT) $594.99. The NPT fitting is a tapered thread and can crack the intake manifold if over tightened.
