I currently am running the original 301 carb on my 400 with an Edelbrock performer intake. while it does run decent, my mechanic told me it's starving for fuel at WOT. would rebuilding it with the HP kit solve this issue? or do I need to change out the metering rods and jets to something else? the current metering rods have a CH on them, no clue what jets I have without tearing it apart. it has a slight stumble when you step on the pedal hard, I adjusted the secondaries and they seem to open properly, just can't get past that little bog.
