99 problems and a Ford ain't one.

did you cut the power on the electric fuel pump when it was loading up to see if that cleared up the coughing? That's simple. Let me know what happens.....I've personally witnessed a 12psi pump to a Holley and know what it sounds like. Decrease pressure by turning the adjustment screw counter-clockwise.

Id take possession of a roller cammed 340 in need of bearings that was headed for the junkyard in a Texas minute. I'd even haul it for him! :-)
