If it was me and I like complicating things.... towing a max of 7,000 I'd look at the 2.7 ecoboost just because it would be so much fun to rip around in. The 2.7 is considerably faster then the 3.5
I like complicated crap too.
I'm hoping to go a little simpler on this project.

I bet the Hemi feels quicker and town just as well given his intended load.
I really like the ford V10, but I think the Wookie is overkill.
A 4.3L vortec was sufficient to pull this load too.
So was a newer 5.3L.
I 100% agree though that a big block or even a 'real' diesel is overkill for my considered ~7k lb load. I want to go with a big block or 'real' diesel just to be different.
The MPG isn't something I really care too much about. I doubt this rig will see more than 3k a year.
The weight of an 8.1 is roughly the same as the stock Toyota 2F engine.
Talk to me about the Ford v10 and what might make it better than an 8.1?

A T400 is a really good transmission unless you want a NV4500 or the std SM465.
I'm not 100% set against a Duramax. It is the mystery weight that concerns me. Too close to 1k lbs and it is a no-go.
The transmission also isn't set. My previous experience says keep the transmission that came from behind the engine for less problems. But I really hate autos
