Editing Talk:Header design

moncacn I agree with your observation about primary tube size. I was wondering if perhaps someone out there knows WHERE to get 1 1/2" long tube headers that will fit a 350 V8 in the common full size 71 to 95 Chevy Van? "Headers By Ed" in Minneapolis makes these. == location == I live in central ND. Where can i find someone to build headers that work near here? == Primary/collector tube diameters == Very interesting article, lots of good info! I was just wondering if someone could maybe expand more on how to choose the correct primary and collector sizes. There are some good examples made, and definitely a obvious trend of "smaller is usually best" showing up, but no real discussion on how to select for your setup. I.E. what if you really did have a high (maybe 400-500) hp engine, etc, what would it take then?
