it idles fine but runs rough and stalls when in gear, when reved up it misses really bad. when reved up i spray either in it it runs great. acts like it starving for fuel. any help, its a great lookin rig, no rust, interior is spotless so i don't want to scrap it. fuel pressure is good

Sounds like its running lean for sure.
Just a thought,check to see if the intake manifold gasket is leaking...
What exactly is the fuel pressure?..within factory specs?
