I agree with many of the posted pricing as it can be anywhere from 3,000 to 25,000+ depending on what you do. I would tell most friends to expect to spend 15K total until things break or you want something else. The problem in pricing is that it depends on what you do yourself and the losses you'll take by going too cheap. I wouldn't skimp out on the fuel system nor the tuning. Also, never use shit gas when you want to make power and your motor will hopefully stay together. I wouldn't say our bottom ends handle 900WHP easily. Once people really start racing on them, they seem to break easier at 850+ when not built. Good luck.
