Andy - you underestimate my notebook - it's about a 400Mb MSWord file by now! :laugh3:
The problem with making it "universal" is that, as I recall, injector spacing has changed a couple times with generational changes to the cylinder head/intake. I really need to get my hands on a few sets of scrap upper end parts that I can play with and won't feel bad if they get wrecked (like some cylinder heads I can run through the bandsaw so I can section them for various experiments...)
Also, I'd like to know what method was used to gain those measurements - you have to REALLY nail things like this down when you measure them! Did you just measure with the rule against a common point, or with a ball seated, or what? The fact that they're sealed with orings doesn't mean that it's not still a precision machining job - it HAS to be accurate or the orings won't seal.
I had planned on making it with about a -6AN, since I don't like Ford-style QD's and I prefer things that work. Same reason I've designed the AW4 -6AN cooler adapters - I wanted to get rid of the QD's. I probably won't have time to make them myself for a while, but that doesn't mean that I can't talk to one of my instructors (since several of them run local CNC shops) and see what it would take to get them made in batches. Any my "fan clutch eliminator" (uses OEM fan,) or...
Making it for N2O would take a little more work - I'd probably design a "doubled" rail for that app. You don't always need the extra fuel, but you need it when you hit the button. The second fuel rail would feed a set of Holley NOSzles or something similar, which allows a dry system (the basic fuel, supplemental fuel, and nitrous all enters the system at the stock injector port) and would probably be easier to tune. I'd already been kicking something like that around...
Essentially, what I'm trying to do (in many places) is get rid of a lot of strange fittings and convert to something a little easier to work with - like when I put -6AN plumbing on power steering - had to fab up adapters for that as well, since the pressure line from the pump is strange. Maybe I'll come up with something better for that one of these days as well...
