engine swapping questions

Hello - I went through the same thing with my car. It was a original 6 cylinder. Here is what I remember...

1. 3 speed will probably not bolt up (not sure) but I would recommend getting a 4 speed. You are going to rev pretty high on the highway iwth a 3 speed. A 4 speed can be found cheap and to completely rebuild it will cost about $300.00 as did mine. It is better than new now.
2. A 6 cylinder radiator will not cut it. I had to replace mine the first week after getting the car on the road. Any good 3 row radiator would work fine. I suggest getting a overflow tank if you plan on driving in the heat.
3. Have no idea - I would guess not.
4. for the price of a clutch - get a new one. you will be better off anyway.
5. I have no idea.
6. I got long tube headers. Any mustang dealer will be able to help with that. I get my parts at cjponyparts.com since they are close to me. They have a great catalog and a easy to use web page with reasonable shipping costs.
7. You will be able to use the electric choke. I have that set up on my 289 and it works just fine. Might want to take a close look at the carb to make sure it is usable. I got a new EB 650 and it bolted up with no adjustments needed.
8. Gas pedal linkage from a 6 will not work. I had to replace and do a little tweaking to get mine to work. E-bay is a god source.
9. If I recall - I just plugged mine up with little black caps that came with the carb. You might want to research that.

These are based on my project and I can not guarantee that they are the correct thing to do, so the best advise I can give is to do the research as you get more involved. Hope that helps a little.
