    I can't find much info on the 8380 except what's on the Summit site https://www.summitracing.com/int/par...8380/overview/ . Any rev limiter facility would have to be controlled from the separate "ignition box".

    Assuming your dizzy is working OK, is there a problem with fuelling? Your symptoms could be fuel starvation in which case you might want to check fuel filters & pipes as well as the fuel pump.

    [I might be well off the mark as I don't know the history of your car/installation ]

    ETA Ballast resistors are only there as an aid to starting and shouldn't affect the car once the key is released from the cranking position. It doesn't mention that you need one anyway


    Justfound the installation instructions https://static.summitracing.com/glob...0_frm23365.pdf which show the installation wiring etc.

    Ballast resistors are ONLY in the system to keep the coil cooler when running, hence they cut the system down to around 9.5 volts, its by passed to 12v when cranking, how big is the fuel line from the tank? (this inc the pick up pipe IN the tank, how much hp and ci?)

    Have you got a feed and return on the carb?

    ok thanks. so should i still check the coil when its at running temp or after a bit of putting foot down to see how hot it is as car runs fine when cooler only when hot it starts playing up big time and cutting out on me.

    The fuel side of things has a mechanical pump on engine still and not sure on the pipe yet will have a measure up when get chance weekend then. What should the pipe size be for fuel so i will know when measuring?

    Engine is a 350ci and dont know hp as not been on dyno or anything but has some performance upgrades from sight.

    Sure its only feed to carb no return.

    Carb is a edelbrock 600 and not sure where float levels are on it only the 2 screws in the front of the carb for fuel and air mixture.

    That Summit listing is for a Ford Dizzy? Looks like 8380 is dual pick up mechanical advance nothing like you have ?
    Maybe you misread the Part number or its stamped badly .. 8360 perhaps . Apparently the early 8360s have only 3 wires and no grey

    Found out it is a 8360 but must be older one as not grey wire.

    What i have seen though is a yellow wire and a material wire coming from the positive side of coil the material wire going into the engine harness side and the yellow wire just taped up loose. Are these the wires that should have a ballast resistor on it as when look on demon tweeks also the coil they sell with a ballast resistor is that same as the one i have but no resistor. Will load up more pics pointing to wires with finger and thumb.
