My 360 build. Input needed.

I have a few questions regarding a 360 out of an `85 dodge pickup.
Will it fit down in a 1975 plymouth duster?
will I have to change anything?

I also need to know the specs. to build a 408 stroker, I will spend 6,000 on this one.
I could be wrong,but I think you,ll need a oilpan from a car?
