Holley problems
I would do a couple of things. First, make sure the float levels are correct in both bowls. If they are fine, find a cheap fuel pressure gage, and plumb it inline so you can watch it while you drive (like run a long piece of fuel hose out the back of the hood, and tape the gage to the windsheild, away from heat sources..lol). What is the rest of the fuel system? What pump? line size, etc. I'm thinking either you're uncoverring the jets under accel, or draining the bowls from not enough fuel delivery.
