74 Duster (318 CI) to 440

Hi guys
im new to the forum
but not new to Hotrods and Race cars

i scored a 74 Duster in pretty good shape for its price

its a 318/906, 8-1/4 rear end Car
Factory AC

1st step is that i see if i can get this SB running 1st.

i have a SBE 76'MoHo 440 , that i threw some basics on
Cam
intake
452 Heads are at the shop for a valve job, milling and spring install.

and i consider putting this guy in the Dart with a 727 that i have to source ( location Dallas TX)

i know i can get the mounts from SCHUMACHER
what oil pan do i need?
(its a 318 V8 Duster so it has the right K Member)

and what Headers other than TTI or SCHUMACHER will possibly work?
i try to keep it $$ in my Budget.

purpose for the Car:
90% Street, maybe some fun now and then on the track

Further what size Carb do you recommend?
750cfm or 850?
Since i mainly street drive it i possibly do a Holley Vac secondary?


Also What Accessories can i swap over from the 318? are any of the SB brackets usable on a BB?
Power steering?
the AC unit?
Alternator?
