Can you replace a 350 vortec with a 305 vortec in a 1996 silverado?

Yes you can. There are a few sensors that are different but after swapping them over it will run. The mounts and bolt pattern are the same. You will certainly be stepping back as far as performance and power goes. Not only does it obviously have fewer cubic inches but the heads lack the flow that the 350 vortec heads have, The 305 Vortec heads also do not have the famous Vortec heart shaped combustion chamber as the 350 heads. The 305 head also has smaller valves and smaller runners.
You can also swap the other way and place a 350 vortec in where a 305 was. I have personally done these swaps with no troubles at all.

Will vortec 350 starter work on vortec 305 engine?
Are you asking if the 350 vortec will interchange with the 305 vortec or any 350 with the 305 vortec? The 305 vortec uses a conventional small block Chevy style large starter. The 350 vortec often uses a high tourqe mini starter. You can interchange them. The mini starter is preferred as it saves space has more torque and normally last longer. Now if you're talking older starters interchanging? Some of the older small blocks used a diagonal bolt pattern and different tooth count.

Will regular 305 heads fit a 350 Vortec engine?
No 305 heads bolt up different then 350 heads If they are 305 vortec they will bolt up. However they do not have the same flow. The 305 vortec head has smaller runners, smaller valves and does not have the same heart shape combustion chamber. Now if you meant the older 305 heads onto a 350 vortce then no they will not. The vortec uses raised runners and the ports will not match. On top of it all the 5.7 vortec has more flow then any other production head. Placing a 305 head in its place would be going backwards.
I'm looking at swapping out my 1996 Silverado 305 for a 350 What will you have to change and what will you be able to retain from the current 305?
Remove the 305 from your truck and set the 350 in. every thing will bolt back up with no problem. good luck
