I have never seen it done, but doing engine swaps always present challenges that you can't see until the engine is in the hole. I always preferred to do what Hotrod Lincoln is suggesting, and that is to swap engine, tranny, and rearend.
The most likely area for problems will be the steering box, clutch linkage, and shift linkage. You have to ask yourself do you want to put in a floor mounted shifter? You will probably need to make up your own headers. You will have to swap in the Ford rad or convert the Chev rad to the Ford configuration.
You would probably be money ahead swapping in a SBC because it is a common swap and it wouldn't be hard to find one to see how they solved the problems.
If you are looking for an easy way to get more power, why not a big 6, they are easy to come by and are basically a bolt in.
I guess what I am saying is, are you just doing this for the challenge?
