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.

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.

The Buick 235 is a direct swap, and most older Buick-Pontiac-Olds engines
bolt up, but have problems with engine mounts, hoses, etc.
I put a 4.3L GM Astrovan engine in a Jeepster, but the bolting to the trans
was the easiest part.

Don't a 3.2 or 3.8 bolt up too?

Wait, he's going into a `71 CJ-5? I thought that automatics didn't, as
a rule, fit. That was one of the reasons for the CJ-7 design -- enough
space for an auto tailshaft.
