Lt1 motor has dead spot

Hello,I was hoping for some info.I have a 1984 with a 91 Lt1 motor.It used to run great but now it misses.I;ve replaced all the sensors.When you give it gas it will stall if you push on the pedal fast.Sounds like knocking.It also smells like it is burning to rich.Could the older fuel pump have gotten weak and it isn't pushing enough p.s.i.? Gary

more than likely it is the "L98" TPI that came in 85-91. intake looks like a spider so to speak, 2 curved intake runners per side. Sound right?
