HEI for your Mopar?

I thought I might build some HEI systems using the GM Ecoils and ECU then build the parts into a nice looking container for everything with the hookups for power and coil connections on the outside of the case.
Something like the picture for the case and everything pre wired inside.
Would anyone be interested and what would you think a fair price would be for this with instructions for the connections?
I want them to be a moisture proof unit.

Also, I'm open to suggestions if anyone has an idea that would make it better.

Right now I'm checking to see if there would be any interest in something like this.

Thanks
