Never did Jeep ship a CJ with an AMC 360 or 401, they only installed the AMC 304 from around '72 to '83. For tranny info, check out http://jeep.off-road.com/jeep/article/articleDetail.jsp?id=277032

However, the exterior dimensions of the 304, 360, and 401 were all identical so it was easy to replace the 304 with the 360 or 401. Plus all of the exterior accessories were all identical further making swaps pretty darned easy. Any of those engines are sweet, a friend has '73 with a built 304 I helped him do a full frame-up restoration on and I'd love to have it.

The first v8 was a 327 offered by Kaiser in 65. It continued til 70.

AMC put a 350 in them in 70 then in 71 they offered the 350 and added the 304 and 360. The 304 and 360 were offered in the Jseries (trucks and wagoneers) The 350 was offered in the special camper edition j pickups and was an option in the wagoneers.

The 350 was dropped in 72. The 304 was offered in the J-series wagoneers, CJ's and commandos. The 360 was offered in the J-series and wagoneer

Same for 73 In 74 they added the 401. The 304 was put in the cj5 renegade. The 360 was put in the j-20 and the wagoneer. The J-10 and the cherokee came standard with the 258 inline 6. The 401 was an option in the j- trucks, wagoneer and cherokee.

In 79 they dropped the 4 barrel version of the 360 and dropped the 401. The 360 2 barrel version was still available in the Wagoneer and J20 but was an option for the cherokee and the j-10. The 304 was still available in the cj.

82 was same but the 360 became an option on all the above but the j-20.

The 304 was dropped in 85 the 360 was still an option on the grand wagonneerand the j-10 but was standard on the j-20 it was the first year the cherokee was introduced as the xj so it got the 4 and 6 cylinders.

86 87 88 the 360 was still an option on the grand wagonneerand the j-10 but was standard on the j-20.

89, 90, 91 the 360 was standard on the grand wagonneer. The j-10 and j-20 were dropped in 89. The Grand Wagoneer was dropped in 91.

All of the above information was found in the book Standard Catalog of Jeep 1940-2003 by Patrick Foster

Just to clarify....the 304 V-8 was available in either the CJ5 or CJ7 from 1972 - early 1981. The 1981 V-8 CJ's are extremely rare and they only made very few of them. All came with either the automatic or the T-176 4-speed manual. (Why anyone would order a Jeep with an automatic is anyone's guess, but I digress.) I only know that they still offered the V-8 in 1981 because my dad bought a new bright red CJ7 Renegade from the AMC dealership in early 1981 and the option sheet still listed the 304 V-8 as an option. I tried to talk him into it, but he ended up getting the 258 instead.

A bit of clarification on grape ape's post.
The 327 was a Rambler engine, the 350 a Buick motor (offered in 68), with the 304, 360, and 401 being an AMC engine (Offered in, I believe 72 model year).

Answer to the question.......
AMC 232, 258, and 401 engines can also be found in late 60's and early 70's International Harvester Scouts and light trucks. I believe the 401 was only offered for a couple of years (72 through 75?), so that makes them some what rare, but if you happen to see an old rusting hulk in a orchard, might go look under the hood.


PS
We used to have a member, fuzzy401, on the site. He dragged a 401 powered CJ. Haven't seen him in years, but he he might be out there somewhere.

You are correct sir. International ran low on their V-8 engines in 1973-1974 and commissioned AMC to build 401 V-8's for their giant Travelall's. I pulled my AMC 401 out of a 1973 International Travelall a couple of years ago and only paid $600 for the entire engine. I'm building the engine now for my 1976 CJ7 Renegade.

The transmissions Jeep used behind the AMC engines have AMC specific bellhousings. I believe a couple of the automatics are a full assembly without a separate bellhousing, so the entire case is specific to the AMC bolt pattern and cannot simply be pulled from a any GM (TH400) or Chrysler (Torqueflight). The manual transmissions like the Dana, Borg Warner, and New Venture options should be compatible if you have the correct bellhousing and just need to replace the gearbox itself.

As for IH using the 401, they rebranded it the SV400. To add further confusion, IH also had its own 304 V8 that is completely different from the AMC and Dodge V8's of the same displacement. If the 304 in my IH 1210 goes out, I'll probably source an AMC 360 or 401 to replace it.
