2012 Pentastar V6 and 8 speed tranny for an A-body

All those wires and fuel system and sensors, computer's is my only complaint.
I have to work on my own engine and this old fart would like to keep running down the road if something just quit I do agree it is a nice light system and it would send my 2.700 lb 66 plymouth down the track and be in the 8.0 class on an 1/8 mile track my even get 7.50
I want an aluminum rear end that will handle a 400 hp car.
This does make me scratch my head a bit.
