thanks 65ch3v3ll3.....I'll go looking for it now haha. Paul's thread is a great starting point, but I know he expressed wanting to do a more "how-to" type post with exact machining specs and such on a start-to-finish instructions type post......I think I have a machinist I can trust now, just need piston-machining specs on what to do with the shoulders so I can get into this..... If you're also doing EFI, MAN will your build be valuable to me haha.
