Is there any COMPLETE kit for a 383 stoker?

Im 15 and i need a lot of help. I have a 383 stroker, just the engine block. Its been boared out by a racing company but im not sure how much. I would like an entire kit i can buy in one to complete my engine and drop it in my firebird. If not, then tell me every single part i need to take a crate engine and have it running and working in my car. Any website and links will be appreciated. PLEASE HELP.
