How much to stock rebuild a 360?

I have a fellow mopar friend that has a stock rebuilt 360 in his duster with a cam and a few bolt ons. he took me for a ride and i have to say i would be happy with a similar engine. I already have a 340 cam and lifters and a torker 340/360 manifold. My dad also has a complete 360 in the garage i can probaly get my hands on. Anyway ive never built an engine before so i dont know what it will cost. I plan on doing as much myself as possible with some help from my fellow mopar buddy who knows his way around an engine. could anyone give me an estimated cost?

As long as i dont win that stroker motor at carlisle this is the next peice of my build i need to save for.
