Build me a Small block

For $6500 bucks you can buy a crate engine with a 30month/50,000 mile warranty that puts out 455HP/510TQ ...(or at least is supposed to put out those numbers) I respect the replys that I have gotten but im still skeptical that it will cost that much for 500hp if you do your homework and find some good deals on parts. But you guys have obviously been there done that many times so I wont argue anymore :)
