440 from an rv?

I didn't know to look if it was internal or externally balanced, but it is a 440 either way. I will probably put a cam and intake in it and drive it til it needs to be refreshed. It has 79k on it. I have a lot of work to do before the car will be ready for it. I saw it and did not want to pass it up. I got the motor, trans, and all accesories minus the a/c compressor for $500, I didn't think that was too bad. Also it has an edelbrock carb on it. Thanks for all the help as I am sure I will need more in the future.
