Building the boosted LSx
Building the boosted LSx So I got some really great news last week, I'm soon to be employed by Lockheed Martin! 
So it's time to get started on what I've been dreaming about for a while now...
I'm planning on a turbo project. Naturally, I've been in the research stage for a while now, but I'm ready to actually start specific planning and development. One of my main goals for this project is to do as much of the work as I can myself. I'm a hands on learner, and to me the experience is well worth the frustration/expense of doing it myself. This includes engine building and turbo system design.
I picked up a copy of Maximum Boost several months back and have read it a couple of times, so I feel good about my turbocharger theory. Likewise, I've researched upgraded powertrain components, chassis and suspension components, and fuel systems. One area that I'm particulary weak in, however, is engine building. I am currently planning on using an O-ringed LS6 block, with forged rotating assembly and main cap girdle, however that isn't nailed down, and I need some guidence in that area. I also need a guide to building high performance (forced induction based) engines, as I have never built an engine. Certainly I know how to install a rotating assembly, but I don't know what to look for as far as clearances and acceptable dimensions (IE blueprinting).
So in short, my first few concerns are:
1.) Find a guide to blueprinting and high performance engine building.
2.) Nail down which engine I'm going to base this on. As I said, I'm fairly certain I want to run an aluminum block 346, however, I'm open to advice on all aspects of this project at this time.
Thanks for the help... I'm sure I'll be back on here often posting questions as I continue this project.

Just a few more tidbits of information about the goals of this project:
1.) Mild streetability. This car will certainly be oriented toward straightline acceleration, however, this is a weekend car that does see street use. I do not wish to give up all handling capability.
2.) Reliability. I believe that anything that is properly designed doesn't break often. Naturally, all-out performance engines are a bit of an exception, but there's no excuse for doing this project and not feeling generally safe putting 600-800 to the ground.
3.) Pump gas. Methanol is an option. Nitrous is an option.
So, tell me what you think. Thanks.
By the way, is there any way I can post a link to this post in the internal engine section? I might get a few more views and some advice from some non-FI engine builders.

I wish I could find a good book on the subject, though.
