Check your IACS- Idle Air Control Sensor on your throttle body. My 90 Camaro sat for almost a year then I had the same symptoms you are having now.

Check the connector 1st(that was my problem) but you may have to remove and clean the IACS as that can get very dirty.

 

well i ran out of day light .... this is in a suburban i picked up yesterday for the 350 i want to put in my 305 car....but i'll check tomorrow

 

A 305 to 350 TBI swap requires the following parts that you should be able to take from the Suburban:
* 350 ESC module
* 350 knock sensor
* 350 injectors
* 350 ECM (Maybe, your best bet would be to get a custom chip programmed for your ECM or use a chip/ECM from a 89-90 350 TBI Caprice.)
