V8 in a 83 CJ7, Ford302 or chevy 350

Another post on V8's for a 1983 CJ7. I have checked the archives but would like to know of any web pages or actual experiences in detail of the process of putting a V8 in a 1983 CJ7.

I have narrowed my selection down to either a Ford 302 or a Chevy 350. I also need to replace (since I'm going with a V8) the tranny and some drive train. In another post I am planning on doing a ground up restoration and will be getting a new frame to start. Probably will have dana 44 front and rear.

What do you all suggest for a V8 and drive train selection and why?

Are there any good web pages (or books) that discusses or show and tells the process of putting a V8 (302 or 350) in a CJ7?

Any advise or actual experiences are appreciated, please add some details.

Thanks,
RR

Re: V8 in a 83 CJ7, Ford302 or chevy 350

no web pages but either the 302 or the 350 would be a good swap. both are good motors so basically i'd find the best deal and go from there. ofcoarse you can't decide which tranny you need to run until you decide what motor. i have had both a ford and a chevy motor in my jeep (and also the stock 258). i liked both. first i swapped in a 351w. it was carbed but i rebuilt it prior to putting it in and it ran great. the problems came when i tried to inject it. i never would run right and rather than spend a whole bunch of $$$ trying to get the right setup i sold the motor and bought a wrecked 99 dually that had a vortec 350 in it. i wanted a motor that came with efi already so i knew what i needed. it was a wise choice because it runs great. i actually had planned on finding a ho302 but it was unlikely i would find one with the 15K miles on it like my vortec had. i also swapped in an auto at the same time and for wheeling purposes i really like it. the auto just flat out outperforms my old granny low np435 that i ran behind the 351w. anyway like i said look and when you find a good deal jump on it. both the for or the chevy will work for what you want.

Well both engines are great choices. I think that if you went with the 350 you would have a better choice of tranies. The SM465 is a great granny low unit. Super strong, and in a light Jeep it would be fun. If the Ford you could go with the T 18 a great trannie also. If you went with an auto, the choices would be better with the 350

RR,

I just completed a 350 TBI, 700R4, Atlas II swap in my 1980 CJ-7 this summer. I have been very happy with the results. A great deal of work but now that it is over I am glad I did it.

Advance Adapters has a small book on conversions for $10. It has a lot of good information. Also check Novak Enterprises web site, I think it is www.novak-adapt.com . They have several pages of information on engine conversions.

Good luck with your project. Just plan on spending more time and money than you expect.

Dan

Re: V8 in a 83 CJ7, Ford302 or chevy 350

I think you'll find that both engines are great choices. I'm thinking that the lines of advise will be equally drawn (Ford vs. Chevy). I'm in the early stages of swapping a Chevy 350 into my YJ, and have done a lot of research on which engine. 305's are small, powerful with a lot of aftermarket support. 350s are a little heavier, but equally as powerful, and even more aftermarket support, as well as having (typically) more availability. I found that Chevy engines havn't changed much over the years, and as a result, it's usually easier to get parts. Hope this helps.

Re: V8 in a 83 CJ7, Ford302 or chevy 350

Here is a 5.0 swap website. I used it extensivly in my 5.0 swap. I was at the same place you are at a year ago. I went with a 5.0 because I could not find a good running complete fuel injected 350 for sale around here. Seems like everywhere I looked there were lots of complete 5.0's. So I went with that.
There are quite a few folks here that have done 5.0 swaps and they all seemed pretty happy with them.

Re: V8 in a 83 CJ7, Ford302 or chevy 350

Well I am kind of alone in this opinion but I do not think that the 302 is a good jeep engine. After driveing my fathers bronco with the 302 I think it lacks the lowend torque to be a good off road engine. The 302 has a bore X stroke of 4.00 X 3.00 compaired to the 351 with 4.00 X 3.50 and the chevy 350 with 4.00 X 3.48. That .5 inch difference in stroke makes alot of difference in where the torque peak is and what the torque is off idle. Don't get me wrong the 302 is a good engine but not in my opinion good for off road use.
Why not use a 351, it has the same exteral dimentions as a 302 and gives more torque and power at lower RPM.

Damn all of you...if you are going to do a V-8 swap, stay true to your roots and get a 304/360 and/or king of all a 401. Then you are still Jeep/AMC and everything will be an easy conversion and you will still be true to the living legend. My 2 cents...
