440 Big Block in my 1970 Dart

Thinking about replacing my /6 with a V8 and I figured, what the heck, might as well go with a 440.

I know many of you have experience here so I figured I would get your thoughts on what to look out for before I get going.

I am thinking about keeping it more stock probably with a 727 trans, unless one of you can recommend some ideas for an overdrive trans.

Here are my first questions:

1. Will and 8.75" axle be ok?

2. If I am looking for a stock or almost stock set up, are there model years that I want to stay away from, or can any 440 be set up to what I need? There seems to be a lot of motor home engines out there.

3. How does a 440 fit in the 70 dart? Motor mounts, radiator, exhaust, etc. what will I have to modify?

4. What size propshaft ujoints will I need?

What else am I missing?

Thanks guys, this should be fun!
