How much does it cost?

I'm just doing a little future thinking here. I am unsure what I what to do for my next project which will be another 72 Demon. I have been thinking of some different kinds of projects including a Viper drivetrain or a Hemi. (elephant motor).

What I am wondering is. How much does it cost to put a 426 based engine and tranny into an A-body? All the work on the car will be done by me as I am set up to do most anything besides machine work. I know some of the alterations that have to be done but not all of them.

Just looking for a ballpark figure.
