Need help/advice with 5.7 swap

I am putting a 2013 5.7 hemi in a challenger. Was told you can't use the milodon pan from Modern muscle (on the 2013 engines). Using a Charlie's pan which allows you to use the stock windage tray/gasket and stock pan bolts too.
A parts list I have to this engine is :
Pan $ 375 (Charlie's )
pickup $ 95
Milodon Dipstick 22064 $79.88
TTI mounts $ 134
TTI headers $730
You will need the factory oil filter 45 degree adapter mopar 53013680AD $ 80.22 ( stock filter hangs straight down and hits TTI mount on passenger side.
You will need a Main cap stud mopar 06506333AA . The charlies pickup uses this stud to bolt to.
This is a torque to yield bolt on main cap , specs for this engine are: step 1-10ft lb 2- 20ft lb. 3-- tighten 90 degrees more.

We are keeping the factory efi, just my opinion is the only way to go .
$2265.10 for the wiring harness, factory efi computer, and o2 sensors and drive by wire gas pedal.
