This is my first Jeep project, you can see in my signature what I have. My carb finaly gave out the other day. 180,000 miles...not to bad. I have a 350 bored .030 over just waiting to go in. This will be my first engine swap in any vehicle. I know that I need to go to Advanced Adapters. For now I want to keep in stock 4 speed in it. What else do I need. I have already rewired the "duck" with the painless kit (painless my butt) Will I still be able to use that harness?? What is the best exhaust with a 350 with a set of shortiess on it?? And will the stock radiator with an electric 15" fan and a high flow water pump be enough or do I need to change radiators.

Thanks for yall help and I will keep yall updated on the project.

you will need to change all motor mounts and go with a good 3 or 4 core radiator

What is the best radiator out there for our Jeeps. I know that I can get one from Jegs but they have a pretty hefty price tag. I belive all they have is the "Be Cool" name brand. Can I just go to my local radiator shop and ask for a Jeep radiotor that has a V8 in all ready, or should I put the bucks in for the one from Jegs??

Any suggestions on the wiring harness??

[fuzz401]

be cool is a good rad pricey but good a regular rad shop should be able to fit you up on a good rad dont go any smaler then a 3 core 4 cor is better i would think so you are going to cang the hook up to match that motor might have to make some wires longer depends on were they are now to the new motor

[rubber duck]

thanks fuzz, I left all the wires as long as possible knowing that I was going to swap motors. So I can just get a new V8 CJ radiator and it will be fine as long as it is 3 or 4 cores. Thanks for the help.

One more questions, I just changes starters, I am sure that I am going to need a new one and a new flywheel, is this true?? If so where can I get a good one for a reasonalbe price??

rduck, good luck with your project. One thing that hasn't been mentioned about the radiator is that I believe that the lower hose on the 350 goes to the opposite side of the the radiator than the stock CJ one. I'm not sure about that but it might be worth checking out.

[rubber duck]

I know that if I go to the "local poop boys" and ask for a upper rad. hose form a 67 chevelle with a 327 the upper hose will work. This is from Jp Mag. They said a universial hose will work on the return hose. I could be wrong. What are your suggestions SanFrom??

I've never personally done the swap so I don't really have any suggestions. I had always heard that the stock CJ radiator wouldn't work with the 350 because the lower outlet was on the wrong side of the radiator. I could be totally wrong on that one.
If you do want a suggestion, mine would be to take it real easy on the rear axle until you either (a) weld the tubes, add a truss, and replace the stock two piece axle shafts with one piece ones or (b) replace the rear axle with something that will stand up to your new engine.
Did I mention that I love the sound of a V8 Jeep?

I know it sounds bad, but I want to put the 350 in so I can get a little better gas milage this summer out of the Jeep. I have to finish my truck, then on to the duck. I will not be doing any serious wheeling until late summer, just a little mud hole where and there. I just need somthing to drive to work. Will a stock 20 year old rearend handle the road for a few months?? It has done fine so far with the 258, in the last 6 months I have been driving it.

As far as putting 350 in a Jeep, last months Jp mag put a 305 in a CJ7. So I will be following there pattern unless someone has anyother ideas, which I will be open to.

you will need to get a conversion radiator. advanced adapters has all the stuff for your swap including the radiator. I am planning the same swap however I am going with a turbo 350 tranny so I can do away with one of the adapters. All I will need is the transfer case adapter motor mounts and 4 core conversion radiator. Good luck post some pictures...

Hey Rubber Duck where you at in VA? I did a 350 conversion on my '71. I made my own motor mounts using the Advance Adapter design. I also used a Be Cool universal radiator from Summit. 4WD also sells conversion radiators for a decent price. I also used a Black Magic electric fan which pulls something like 2800 cfm. I would've preferred to keep a stock mechanical type but it would've hit my front crossmember. I have an early "short-nosed CJ" though so you might not have that problem. I see in your profile that you're in the Navy... Norfolk area?

[rubber duck]

BESRK I am in Newport News by CNU. What about yourself.

I am plaining on puting some pics of the duck on here as soon as I can find my cable for my camera. I just moved, now I cant find anything. Thanks for rad. advice, I will check summit and see what is up.

Now that cooling is done, what is a good carb size for gas conservation, anything has to be better than the 9 miles to the gallon the 258 is giving me.

Check out www.novak-adapt.com for info and for adapters and motor mounts. Personally I think Novak makes a better product and I'll guarantee you'll get better customer service from them. Eric Novak really knows his stuff and is usually glad to share what he knows with the customer.

[rubber duck]

Cool web site, I will be looking more into them. At least from looking at the site it seems easier than Advanced's does. Thanks
