BBC Build... im flipping lost....

[biohazardbill]

So we want to build up a 454. We would like it somewhere between 500 and 600 horsepower. That number is based off the idea that we like the lobe sound at idle but when we hit the gas would like it to go go go.

Mechanically speaking I can diagnose and fix most anything however when trying to build something from scratch, determining compression rating etc I have no idea where to start.

I have a stock 454 from a RV. Looking up the casting numbers off the block and heads it has peanut port heads, however I picked up a set of 781's today at a reasonable price as everything I have read etc. said they are great up until you clear 700hp or something, and im not worried about shaving weight so why not. If they dont work I can always resell em so no money lost.

This truck will not be a race truck. The motor must be reliable as i will be driving to and from shows at some point. I have looked up and googled terms like big block recipe, parts list etc for any type of guidance on a recipe of what to tell a machine shop to do to the heads and block and what parts to put in to achieve something in that range. Most of the articles and such i read seem like its directed to a savvy engine builder which I am not. My biggest fear is doing stuff twice.

So I ask..
what do you do to get this thing up there in that range? Does anyone have a recipe so to speak. By recipe I mean what parts you need, what needs to be done to the head and block that I can convey to a machine shop etc?

Any help appreciated
