For an '84 Silverado, a 350 Vortec engine would generally be a better choice compared to the 305 with a 488 cam. The 350 Vortec offers more displacement, which translates to greater torque and horsepower potential, making it more suitable for various driving conditions. Additionally, the Vortec heads provide improved airflow and efficiency, enhancing overall performance. If you're looking for a balance of power and reliability, the 350 Vortec is likely the superior option.

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.
