Stanton Magnum Build?? Tranny?? Blower?? Painless Wiring?

Proud 76 Dart Sport owner here.

I am just now getting into the real heart of my rebuild. I half-heartedly started on it before, lost my drive when my wife got on my case, and am now proud to say I am delving head first into a full on resto-mod for it. It is almost entirely stock still so my options are still very open. But not for long. So, here's my plan:

Redo all the wiring with a painless wiring kit
Tear out the 318cc
Build a Stanton 360 Magnum from the stanton block up.
And replace/restore the original tranny, suspension, drivetrain and everything else under the hood while I got the motor ripped out
Eventually throw a blower on the engine and possibly a NOS system (mixed feelings on nitrous).

So I would love input. Good parts for the Stanton 360?? Anyone have any experience with these wiring harnesses? Who makes a good blower system for the magnum engines? Tranny's for that much hp/torque? Also, how much modding am I going to need to do to the rear end when I start pushing 450/500 HP and a ton of torque?? Thanks for your answers!!!
