The problem is, one thing leads to another in any build. So a brief "run 9.5:1" leaves a lot out IMO. You also want to be careful talking to most tech lines. The "response notebook" only says so much. There are other builders here and on other web sites that have all kinds of good ideas. One of my favorite haunts is Speedtalk.com . They get very heady, I'm more of a watcher there, but the tech archives in the engine section is second to none, and guys like Darren Morgan and Larry Widmer are members there. They will answer even teh most mundane question with respect. So use that resource too.
