IH 466 into an IH 1466, what does it take?

I have access to a 1979 IH truck with a rebuilt 466 and know where I can get an IH 1466 with a bad engine. I know it's common for guys to swap the 466 into tractors but what does it take? Will any year 466 swap right in? Bellhousing the same? Even though I'm a JD guy I'm considering this project and am wondering what it takes to make it work?



Thanks!
