258 direct replacement for the dauntless??????
ok heres the story my father in law recently purchased a 71 cj5 with a
seized up dauntless v6 in it and i would like to buy him a motor for it for him for christmas. i found a 258 for 100 dollars but i'm told it will not be a direct replacement. #1 does it have same transmission bolt pattern on back of block? #2 is it just because it is a cj5 and there isn't enough room under the hood? thanks in advance |
Re: 258 direct replacement for the dauntless??????
The v6 is a GM product, and the 258 is an American Motors offering. The
transmission won't bolt up. You may get an adapter from Advance Adapters, www.advanceadapters.com, but it will cost a lot more than your $100 258. If the 258 comes with the clutch, bell housing, and flywheel, you might have some luck. If it was in a CJ, and you can get the motor mounts, clutch linkage, and a whole bunch of small parts that I don't even want to think of now, you might even make it run. You might like to investigate why the v6 is seized. The vehicle might have been left outside in a rainy environment for long enough that the rings rusted to the cylinders. I had a 318 like that once, and eventually got it freed up and running.

Re: 258 direct replacement for the dauntless??????
ok i already have all the parts i need from a cj7 project of my own i'll
probably donate to the cause of getting said jeep running and out of my garage. i know the dauntless is a gm motor but from past experience my turbo 350 transmission was bolted to the back of a 258with no adapter, so i guess i was just fishing for why the motor would not work (or so i was told) as a replacement because i wasn't given any particulars just that it wouldn't work |

Re: 258 direct replacement for the dauntless??????
The answer depends on which transmission you have in the CJ 5. This page
says that you need an adapter to bolt a 350 Turbohydramatic to an AMC engine http://www.advanceadapters.com/catalog/025.html The following two pages have some information on your year, which I believe is 1971 http://www.advanceadapters.com/catalog/020.html http://www.advanceadapters.com/catalog/021.html I don't recommend either for or against buying Advance Adapter parts for your project. It is just that they have collected a lot of information in their catalog, that you might use to figure out what kind of transmission you have. I don't believe that the v6 uses the same bell housing pattern as the v8, but I am not 100% sure on that. From memory, it is a Buick engine, not a Chevy.
