Just where would an individual go to find and purchase a set of fenderwell headers for a ford pickup. Does anybody manufacture them. If no one makes them then I need info on how to make a set. What exactly is the purpose of a collector other than combining the main tubes to route to a muffler? Could long equal length primary tubes beleft in-line like some of the big top fuel dragster. JUST CURIOUS!
<font color=purple>Not sure where you'd get them, but I would think a local speed shop would be your best bet. You definitely want to have a collector - though a flange for the muffler isn't necessary unless you plan to run full exhaust. Bringing the tubes together creates a scavenging effect & creates additional torque w/o hurting your HP. Definitely do NOT run the "zoomy" type headers (no collectors) you see on the blown cars on a Super Stock or Pro Stock truck. It'll hurt your power.</font color=purple>
I just wasn't sure about the whole subject. I'll probably end up fabbing my own with the help of a local muffler shop I know pretty well. They'll have the machinery to bend the pipe exactly like i need it. What length do you think the primaries should be?
<font color=purple>Can't really say on the length. Lots of theories on that & it's highly dependent on application - ditto the diameter. I'd hate to speculate on someone else's engine for that as I'm really no expert.</font color=purple>[img]/wwwthreads_images/icons/blush.gif[/img]
Primary length will vary between engines and powerbands.
I couldn't find fenderwell headers for anything thru the major makers, I bought some Schoenfield circle track headers, and did some cutting and welding, they are great. Take a look at their stuff.
