Default 7.3 Powerstroke??

Hello all, when I originally picked up my 78 terra I did so with the intent to pull the gas burner and drop in a new 7.3 I already have. However this terra came with a rebuilt IH 392 already in it and from what I understand these 392's are very stout on the low end so now I'm in a quandary.

Has anyone else here attempted to drop a power stroke in a Scout? What are some of the pitfalls to watch out for? I would really appreciate any input pro or con. Thanks!

Even though you have a 392 the 7.3 is longer wider and heavier than the 392. Size does matter and it will be tight, but it can and has been done.

The 392 is a thirsty beast it does have great low end pull but a 7.3 is better and easier on fuel. Depending on what you use it for you May wish to change your axles for heavier ones. I don't believe the 7.3 will bolt up to the automatic or any 4 speed that came originally with your Scout

Thanks for the input. Once I'm finished with the restoration I intend to use this Scout as my daily driver and was thinking that the diesel would be best. Then someone else can have the 392 for a killer trail machine. Have you done this swap before? Also can anyone tell me what a fair price would be for this 392 if I sell it?

Ihave not done it with a Scout but rather a Travelall. Ih64scout has a thread on the binder planet under the diesel section which he details the process from start to finish

I have a project where I have a 6.9 with a turbo in a Scout II. I did have to remove some of the firewall for the downpipe, but it's in there. The 7.3 ps will probably need a little more room because the turbo sits farther back on the engine.
