I know this isn't covering any new ground but I'm still not clear on exactly what I need to drop a 460 into my '75 F-250 4x4 with a 360 2bbl,
C6, NP203 divorced and Danas front and rear. I just need to know if it's worth the trouble and where to get all the stuff to make it as painless as possible.

 

You will have to swap tranny, most likely the drive shaft, engine perches, and probally other things.

Suggestion, rebuild the 360 as a 390 if you want more.
