I'm looking at buying a 345 international v8 with an auto torque 727 and a Dana 20 and Dana 44s front and back this is in a 1979 Scout II. Now I know this is a cj site, but everything I've read says this is a great combo. I'm looking for any and all opinions! Thanks in advance!~!:)
 
My only concern would be aftermarket support for the 345. What other vehicles was it in?
 
I have to agree on the 345 support, could be slim. Obviously you didn’t get lucky enough to end up with an OEM Dana 44 rear in your jeep. There are some issues with the cast on a CJ in relation to a Scout that you most likely already know and you would be swapping out a Dana 300 for a Dana 20 reducing your crawl ratio, all in all I would question the swap unless all the donor parts were free. You might be better served to stick with a Jeep motor (AMC V8), Jeep tranny, and keep the Dana 300; OEM parts and virtually no adaptors.
 
I'd wheel it as is, might not be a jeep but still a good unit.

I was planning on driving the scout as is. Just wanted some more opinions on the motor and trans. On the aftermarket support I've found a few online that have parts for it. When I go look at it next weekend we'll see.:cool: Thanks for the opinions keep them coming. I didn't think of the aftermarket support on the 345. Thanks:)

The 727 is a great auto....strong and very small, it works great in Jeeps. I have friends running them behind 401's in CJ5's....that's how short they are ;)
 
You might wanna also look at replacment parts at the parts stores. I do not think Scout seals, ball joints, rotors and such are a high volume sales items...we all break down sooner or later

I get it, I'm a Jeep owner and ad-block detectors kinda stink but ads are needed on this site. This is a CJ site, all the ads are set for autos (some times others get through.) I cannot make them just for Jeeps but I try.

Please allow ads as they help keep this site running by offsetting the costs of software and server fees.
