Re: 345 from 64 IHC dumptruck
First of all, what kind of mounts does your scout have? saddle mounts? I am trying to think, somewhere along the line I have read that the reason the single front mount was used, and I believe that was simply because of the position of something but a brain fart keeps me from thinking of the answer. I am sure though that you should be able to mount the engine in your scout without too much trouble.
I am unfamiliar of the 8 cylinder engine mounts in the scout, but in my truck, and in a travel-all I owned (both are 73') both had the single mount under the harmonic balancer. I can bet that there are probably holes for this type of mount on the front of the frame on your scout. Even if it currently has saddle type mounts.
Now for the transmission, is it an automatic or manual? If it is an automatic I can almost bet that it is a torqueflight 727. If it is a manual, then I can say I have no idea.
