Finding the right 460 that I can work on for my F100

I have a question for you guys I am thinking about buying a 1979 F350 that has a 460/c6. I was worried about the motor not being a proper for what I need it for because of the emissions and smog equipment they used on the truck back in 1979. I need to know if I can still use the motor and get rid of the smog equipment to make it run better?

Here is the craigs list ad I was looking at to give you guys a better idea of what I am trying to do.

Mike, that engine will work. be a shame to cut apart that 79

thats good to hear that I can use that motor I am sad about tearing the truck up but I am sure people would need the parts from the truck.
