To answer your question, yes it can be done. Will you use a Chevy transmission also? Here are the things you'll have to change:
- New engine mounts
- Build new headers
- Relocate Transmission mounts
- Relocate shifter hole on transmission tunnel. You'll have to deal with a hole in the carpet.
- different size drive shaft
- Radiator hoses

I'm a Chevy man also, but I have been assimilated. Three major reasons for using a ford engine are:
1. Less work, no modifications to make it fit
2. You can dress the engine to look original
3. Increases resale value

If these 3 reasons don't bother you than go ahead and use the Chevy engine.
