I've gone to making my headers out of stainless. Way better, less hassles with rust and fatigue. You can get mandrel U-bends of every flavor from Woolf Aircraft in Romulus MI.

John I got mine here on the board. Awsome service.
I got the tubes bent to what I needed by Ted's Fabrication  (225 digger on this forum).

last I heard Ted was not doing small order stuff anymore. Nice guy  and nice product,just pretty sure ie has too much work with big order deals.

Ted is still doing things for smaller orders. He just wants some flexibility with the orders as he will do the smaller run stuff between the big orders.
He let me know today, which is great, as we have another engine to do zoomies on. I will get my info to him in the next few days. His pipes were spot on with what I sent him for measurements. Great person to deal with also.....

If you can use 1-3/4 I made mine from this speedway kit. A lot cheaper than ready made. (If on a budget).

You could probably sell the flanges.

Not sure what a Chevy bend is but SPD sales many different bend radius’s

Seven years ago, Ted's Fabrication (aka 225digger) did excellent for my special order.  Stainless Steel and bends/length were precision done.  And he was most competitive price plus shipping I was quoted compared to 3 other businesses.  Thanks again Ted.  Alan

I just finished building mine with 2.25" diameter 6" bend radius for my SBC

Paul,  what SBC head is that which uses an even spaced port design???  Ive done it with a SBC "spread port" design but required a little fancy footwork to spread the pipes

  To  Buickfed

   how about a pic of the motor/head

dreracecar,

the buick 350 exhaust rectangular ports are similar to the sbc and overall length is close, but not enough to modify sbc's to fit.
if i knew how to put pics here i would.....

Most commercial offerings go 45* 90* 180* bends,  having  custom bends will get pricey due to set-up charges.  Go with  6" radius bends cut in half to get length out of the port instead of a tighter bend and a straight off the port. Exit angle will parallel the flange angle and only 4  180* bends are needed and you can fudge the cut at the flange to get them standing straighter if you want

If you can get Ted to bend you a set he has no problem with custom bend. I use to get 3 different angle per set and cost was very reasonable.

I've been told Stainless headers crack up? Is that an urban myth?
Title: Re: Zoomie pipes wanted
Post by: dreracecar on May 22, 2020, 08:15:36 AM
only because people tend to make SS headers thinner and that makes the service life is shorter,  You make them the same gage as mild and they weigh a ton.   So you wind up spending twice the amount for SS and can get 1/2 the service life

You might look at Shoenfeld Headers (? ) web site - lots of oval track headers and parts.  I have used them for plates and u bends.

  Buick 350 header flange is not super common as a SBC/BBC would be.  Lots of tube bends out there from varius supliers

When I did the set for my altered I made sure there was back shielding gas on the inside of the header pipe. I use a mini-Nerf football to hold the purge gas line inside the header pipe as I'm TIG welding the outside. I race pretty much every weekend during our season and after 19 years of use no problems so far.

The specific gravity for stainless steel is around 8000 kg/cu m vs about 7700 kg/cu m for mild steel so, yes they will be about 4% heavier than a mild steel set. But since you don't have to coat/paint them I'm calling it a wash.
