I got all the pipe to make some headers and I used to see somebody selling steel flanges just for this.. Anybody know where I can get some?
Funny, I'm looking for olds 455 flanges that aren't $150. I could buy used headers and cut them up cheaper. http://www.headersbyed.com/__cadillac.htm Alliance vendor---> http://www.hotrodchassisandcycle.com/parts_cars.php I just bought these flanges, I'll let you know how they turn out. http://www.noxiouscustoms.com/flanges.htm
check http://lakeheaders.com/Home.html they may be able to provide just the flanges but i'm not positive.
Try USA Stamping Company on Ebay.... http://stores.ebay.com/usastampinc Decent stuff, and the price is right... BTDT Jeff
There are a lot of water jet or plasma cutter guys out there. With the economy like it is I would think if you supplied a pattern you could get some cut for well under $100. The last set I had cut was 3 years ago and the were $60 a set for a 390 Cad. I would recommend using 3/8" mild steel.
I don't know squat about Cadillacs, but this place sells headers and flanges for 425-500 Caddys. Are they anywhere near the same? see page 4 for headers see page 26 for header flanges http://patriotexhaust.com/catalogs/pdf/patriot/patriot_2010.pdf They have a lot of cool stuff otherwise...fun to dream...
