v8 kframe vs Schumacher kit

I'm in the middle of swapping out my 318 to 440 with all of the schumacher stuff including headers. I was told this would fit in 1974 dart with power steering and brakes and aluminum valve covers. After 4 mechanics and several buddies I have come to the conclusion there is no way to make it fit. So know I have ordered the Altercation front suspension. It's maybe just my car but man has this gotten out of control. I can say though at the end of the day it is going to be sweet though.
