Gen lll hemi install in a 67 barracuda

Hey all
Starting to make a list of parts that I need to gather to install a gen 3 hemi. I have a lot of questions
Can I use my 68 biscuit type Kframe? Noticed can’t figure where to buy the correct mounts
Do I need to change the whole front of the motor with the kit from Holley?
The 5.7 is out of 2017 Durango.
I know I need to change the oil pan. The oil filter right now has the 45% angle attachment on it or do I need to change that?
What about the computer for the motor do I need to use Hotwire harness? I don’t have the original computer for the motor.
The car is a four speed can I use it for my trans or go with a 727 or a newer trans?
What about headers?
Radiator?
Like I said I’m starting to put together a list and have a lot of questions
Thanks in advance for any help

Holley has a lot of options for A body swaps, I was shocked that they had options (engine mounts, transmission mounts, and oil pans for my 71 POWERWAGON, I went with Holley terminator x with for my truck Gen III hemi. Pricey but easy installations and user friendly. My truck has space for days for this swap, so space wasn’t an issue. I went with 46rh, bolted up to the newer hemi. Your 4spd bell housing will bolt up, crank hub required no modifications.
