Check the jetting suggestions. If the fuel jet is bigger than the juice jet, it's really fat. There are some old instruction and revised ones. Monte Smith redid most of the jet packages IIRC.

Check the holley site for a new set of instructions.

I usually start with a fuel jet about 8-10 sizes smaller than the juice jet. Ask Monte Smith about that over at the bullet or slo... I mean moparts.
