Going from fuel injected to carburetor is easier but you still need to think about fuel delivery as you only need about 5 PSI. So the fuel injected pump that produces higher PSI is not going to work. You will need to just use an inline fuel pump for these engines.

The biggest two issues that you are going to have are one, mounting the engine as you will need to change the mounts so that this sits correctly. The fact that it is a Chevy makes that as easy as possible as there are a ton of issues.

Next is the transmission. That will bolt to the engine but depending on what transmission you use, you will most likely need to change the crossbar mounting location and then you will need to cut the hole in the floor larger to fit the shifter.

Then you are going to have a lot of small items that you are going to have to think about like plugging o2 sensors, new wiring harness, power steering.

Basically the list is going to get longer for you as you work through this because there are things that are going to come up that no one expects.

However, if you plan on solving these large items before you start then the rest will be pretty easy.

If you have not selected found the motor and transmission yet, I would research you options and select the ones that will just fall into place in your vehicle, or at least have mounting adapters so that all the hard work is taken care of and you just need to install them.

Once the engine and transmission are in and mounted, the rest is just a matter of working through each hurdle that you come across. Again, the fact that this is a GM product makes this very doable.

Please let us know what questions you have as you work through it. Also, we have a couple video series on engine swaps and car builds if you want to check them out.
