My 84 z28 a 350 .30 0ver with an edelbrock 650 and an edelbrock intake. 480 lift comp cam. When I take off and mash it to the floor, sometimes not all the time it will like bog when I get to about 50. I can let off the gas for a sec and then hit it back down and it takes off fine. Is my carb to quick for my fuel pump? Is it just sucking it dry? What kind of in line fuel pump system could help this and how much would it be. I know what your thinking, probably the fuel filter right. Just changed the fuel filter and the plugs last night. Has anyone had this problem, what did you do?
