Intake Manifolds

I get you Dan, I used to be a lot like you, except I bought books, a lotta, lotta books in an era when Dcr and Quench was not even talked about. Trying to get that information was like pulling hens teeth. Finally, when I had exhausted as many roads as I could find (this was 1998/99 before the internet exploded) I did all my calculations by calculator, and pulled the trigger. Two years while my car was in the bodyshop, I read the books, the magazines, extracted data, and played the numbers.
Time well spent, as the engine was a hit, almost right off, in spite of the fact that the local engine shop refused to screw it together for me on account of 11.3Scr was gonna blow it up.... they said. Well it's still running today, more than 23 years later, so screw them, lol.
Dan, it's pretty hard to learn unless you have a teacher, or ask a lot of questions. I say, keep asking the questions. Bullies be bullies and mostly they never change. And you know; they get their comeuppance in the end. Keep on forgiving them, cuz you know your health depends on it. I'm in your corner, brother.
