just got this car and i dont know where to start.....

Free! WOW!

How about a closer up shot (Both sides and inside the engine compartment) to see what exactly is there and not. It doesn't look like it needs much.
What year?

A Chiltons book or on line look at the parts exploded veiw would be of help for you.

It appears, though I can not really see so well, that you need upper A arms and it's hardware, shocks, spindles brake hardware....

As far as engine goes, decide what you want. If the K-frame is for a /6 and you want to restore it with a /6, there here on line at FABO to get.
A engine swap is easy to do as well if it is a /6 K-frame and you want a V-8. I'm not so sure about the reverse though. V8 - /6 swap.
