Sorry to , but I am tired of reading through the searches. Someone once on this board turned me on to a web site that sold HC1 flanges for building larger downpipes, and they were cheap. Does this ring a bell?

Thanks!

H1C as in stock ? I believe its something like www.airflo-online.com. Not cheap though.

 

I have a 16cm housing, and a very nice mandrel tight radius 4" pipe for a down tube. I just need the flange so I can weld 'er up.

p.s. bgilbert, have you dynoe'd your truck? Looks like you have a maxed out 1st gen and I was curious how fast your truck is.

 

I did find the old links on flanges, but they all seem to be dead links.
Any help here?

 

I'm stressed out to the max, and need stacks!

If I can score a flange I may do a single 4" stack with a gentle turnout.

 

Could you cut the flange off your existing downpipe and weld it to a 3''-4'' adapter, the weld the whole mess to your short radius elbow? That's how I plann to do my own downpipe, when the time comes. Maybe I'm missing what you're getting at, though.

 

I wanted to build a new downpipe with a new flange because mine has 300k miles on it (and I would rather have the old one in tact in case my rusty welding skills blows too many holes in the new parts!

 

Gotcha. I'm trying to learn on my new-to-me MIG...made lotsa holes in stuff myself. Try this:

There's an adapter section, too

 

Ok here ya go: http://store.airflo.com/ad311.html. If that doesn't work, search their site or google for 6BT flange.

 

Rip rook has the flanges also and I believe at a better price. Don't know how to contact them though. Someone will probably chime in.

 

www.stansheaders.com Call him he has them...

 

No dyno yet. I should have a number by spring time. Big pump, sticks, turbo =?? Fast?? Not this slow shifting 5 speed. I'm sure the clutch and trans would be layed out about mid track if I ran it down the strip ...

TRLMAN, you need to correct your sig, you have a W350 not a D350 model. C'mon now, you're a long timer, you should know W= 4wd, D= 2wd.

My 5 speed shifts really fast , but I need a bulletproof clutch. If I get a clutch that will clamp her down something else will give, maybe the transfer case. I have repaired/replaced the trans and rear diff, so hopefully those are solid enough. I guess it's a good thing that I haven't been able to afford the clutch! My current clutch (LUK) is like a tranny nanny .....
