Thats not how it works. You dont pull a motor with a spun rod bearing and fix that one problem. You do the whole thing. No good shop is gonna get involved in that mess. Its toast. Fix one thing and they will see you back at their shop in a week with another spun bearing. You can do it your self, or buy another motor used, buy a rebuilt block or have yours rebuilt.
As far as labor there is a number of hours to remove and install. They look it up in a book and the number of hours x what they charge hourly. I would say $1200 give or take. At that point you would need to look at a few things. If you want headers now is the time , its a pain in the A$$ putting headers on a mod motor. You have to lift the block off the motor mounts. A new clutch or at least a throw out bearing a good idea. If you have time and the money I would have the engine rebuilt by a good builder. It will cost more money and time but will be a better motor in the long run. The ford service block is a driver car way of looking at it.
