    if the fuel pressure is good(60 psi), then check the ignition coil for corrosion

    yes it does, the terminals should be clean. if not you can try to clean them but replasing the wire and coil may be necessary

I averaged 9-10 MPG in my 98 w/5.7 l vortec.
cap, rotor, plugs, wires, O2 sensors, fuel filter, and fresh air filter are the best way to peak MPG's

You can use any 305 motor. Like you said you will have to exchange parts from your old motor to the new one. Just make sure you don't go to far back, because the old 305's don't have the injector ports. Then you would have to replace the heads also.

Untill recently GM didn't change much of anything as far as bolt paterns You could bolt up a 350 from 20 years ago to your transmission and motor mounts. But that is not really what your wanting to do. The question is do you have a "vortec" or is it TBI. The vortec motor says vortec all over it (they were pretty proud of it I guess) The earlier TBI motor, at first glace look just like the old carburetor versions until you take of the air cleaner and find a throttle body instead of a carburetor. The two are not interchangeable as to the electronics, they are way diffract.

Wont start


simpler that exposing the throttle body just depress the accelerator 3/4 and try to start.

If like before, the vehicle starts... watch the rear view mirror for black smoke

both indicates a leaking injector(s)
