    302 Laying down

     



    Help!
    I have a 302 bored .060 over.
    Mild cam
    Edelbrock intake
    Edelbrock 650 CFM 4 barrel carb
    Headers
    MSD 6ALN box
    Automatic
    79 F100

    Was getting on the highway and had it to the floor, went through all the gears fine, when I reached about 65 it was like someone turned the switch off. It came back, pulled a little bit and did it again. I let off the throttle a little and then floored it again, same thing. If I am not all the way into the carb the engine pulls fine, seems that the problem is only when I am in WOT.

    If I shift to first and floor from a dead stop it it pulls like crazy all the way up till the MSD kicks in and starts dropping cylinders like it is suppose to.

    What is causing this???????

    But the box works if I don't shift.
    It will bang the limiter just like it's suppose to.
    It only does it when I am at WOT and letting the truck go through the gears

    chance to empty your float bowls your pump is prolly not enough

    383 might have some thing. You might have to adjust the float in the bowls. Also check the fuel filters.

    I'm using a mech pump.
    I will check the filters and make sure I don't have a clog.
