My car has a 460 so I can't be of much help there.
I didn't get a builders manual when I bought my car but I was able to get all of the support that I needed directly from Midstates. Since then the company was bought by Shell Valley and last that I had heard there were a few of the original people that were still there. You might try contacting them if you are unable to get your questions answered here.
