Chevy 4.3 into a CJ5

I am looking at putting a 4.3 v6 from a Chevy blazer into my cj5. To avoid some of the adapters I'm going to be putting in either a Muncie SM465 or a Muncie SM420 along with a NP205. By putting in the NP205 i can eventually run a doubler if at some point I decide that its needed.

Plan is to find a full blazer that still has a good motor in it for the swap so i can have everything that is needed. By this I mean the wiring harness, computer, rear axle, motor mounts?, and i am sure i will find a few more odds and ends.

Just want to know if someone here has done the same. Looking to see what it involves I know that there is a decent amount of work that is involved with an engine swap. Just looking to see what problems or issues others have run into.

Thank you

Carl,

Check out NOVAK JEEP CONVERSIONS on the internet. They have a lot of useful information on most jeep conversions. I am sure they can help.

Take care,

Check out "YJ V6 Conversion" if you want to see a frame up restoration of my 1992 YJ.

Check out "WWII Jeep Photos AND Restoration of..." if you want to see the original JEEP in action...

if you're going spend the money and time to go through a swap you might as well go with a V8 of some sort. I did a 5.2 swap and cant see a v6 being worth all that effort.my 2 cents

Was thinking of doing a v8 but decided not to. For what I am going to be using it for don't need that much power. I also used to own a blazer and the 4.3 had more power then I ever used and was a tough little motor.

Carl,

Check out my signature for information about my thread. I dropped a 4.3 in my 1992 YJ. It is "frame up" restoration but it has a lot of information that can help you. I posted a lot of photos and put a lot of information just so people like you can see what it is going to take and make an informed decision. It is missing in a lot of threads with conversions.

Take care,

Thank you again

Late model V6 into CJ5

If you use a late model V6 with injection, using the late model computer and wiring harness, be aware of all the security interlocks.
I used a 2006 V6 with it's wiring, and had to reprogram the computer to bypass the ignition magnetic lock, and had to add a 2nd stage wiring to the ignition switch in my CJ. The computer apparently looks for two inputs at the same time.
