Slant six swap HELP!

Greetings-
I’ve been away for a while.
I have a question about a slant six swap. I have a friend with a 65 Valiant with I suppose a 225 with 904 trans. This motor overheats and he wants to replace it. I have a low mileage 170 (2463230-9) and three speed manual out of an A100 van.
1)Will this motor mount to the 904?
2)Will the oil pan and oil pickup transfer over from the 225 to the 170?
3)Will the throttle and kick-down linkage transfer over to the 170?
4)What other factors do we need to address?
Thanks guys and gals for any and all help and info.
