High speed is usually electrical related.

Distributor in good shape?

new dizzy, plugs(e3), cap & rotor(bwd select), accel wires, and street fire(msd) ign box. cap & rotor are the team rush.
 
Clean fuel filter? Lift pump pumping enough volume? Not sucking air anywhere? Best i've got.

Only does it in 1st at 3000rpm?

i got two new fuel filters. a inline one before the pump and a new stock one before the carb. ya only in first at about 3000rpm before i shift into second.

I'd try taking the filter before the pump off, stock pumps have a hard time pulling fuel through a filter.

So your saying in 2nd and 3rd gear you can go past 3000rpm with no miss right.
