what would it really take?

I am new here and also very new to doing anything with cars other than drive them. I recently bought a 74 duster and have been working on it for about three weeks now and having lots of fun spending time with my 13 year old son working on it. We got some minor wiring fixed and got it running, and have been cleaning it up when he gets out of school and on the week ends. a few days ago we (with the help of a friend) pulled the motor and transmission and are in the process of rebuilding it. With that said ( so you all realize im really just reading how to do every little thing and dont have a clue on my own) but I am learning. I have found a 72 duster here locally for sale that has been used only for drag racing and i am sitting here wondering what would it take to transform this drag car into a street car? I do realize in has no interior and no gauges and that would take some time to track down all the pieces , but besides that what would need to be done as far as the motor and transmission etc.. is this to big of a project for a beginner? here is the link to the cl add if you would like to see the car and read the info. I hope this isn't a silly question :)
