    Engine Ignition Timing Issues 1985 Fox

    So here's what i got: 1985 Mustang, engine from Summit (Blueprint Engines), Holley 4160 carb, rebuilt Metric AOD with 2400 stall converter, 8.8 rear with 3.73's. I got the car on the road last summer with the 'original' engine but found it was wore out so i never messed with the timing. Now...

    Timing not advancing

    Just swapped in a 351w carb Into my 86 foxbody and for some reason the timing isn't advancing under acceleration . It is mildly built. Any help on why this might be happening or what causes this?
