Will FPA Tri-Y headers support 700hp?

[482supersnake]

No problem.  As a second option I do have an old set of 2" tube Galaxy headers that have solid tubes. I stared to modify them for a project but switched to stainless. I would make you a good deal on them if you wanted to try your hand at fabricating some yourself, or there are some forum members up north who have experience fabricating headers. (TomP) I live in the Browns point area.

Crites makes 2" headers as well

I like my FPA tri-ys in my 67 Cougar and was going to say what others said, talk to Stan or FPA and get them to make a set with larger tubes.

What about Mad Dog headers? They list bare steel header with 2" into 3-1/2" for early 60's Galaxies at $450. It's a long tube header so ground clearance could an issue and they do not have a picture on their site but it could be worth a call to get some more details. Part# 9201

I have fpa tri-y's on my lowered 62 galaxie and have not scrapped them going over speed bumps and I am sitting pretty low. It's currently up on stands otherwise I'd measure for you, but I'll put it this way its low enough that I cannot slide a normal jack under the front. I need one of those low clearance jacks. I will say as well that my springs are like 20-30% stiffer than stock. I also go slow over speed bumps. Additionally the pipes coming off the collectors are the lowest point not the headers so the pipes would be first to suffer. no biggie. I could take pics if you want.

Obviously I've got no dyno experience to back it up.... but my 63.5 Galaxie has FPA headers that appear large enough to support more power than I'm making.

[Rory428]

I seem to recall in Jays intake comparo book that the 1 3/4" Dynomax truck headers made more power than many of the larger headers he tested.

[westcoastgalaxie]

Those truck headers made power due to the exit length from the port not their primary size. Trucks have more room under the hood and the headers can make a straight exit out the port for longer than in any other application. Just like look at Barry’s dyno headers.

Talked to the guy at Stan's in Auburn and the quote I got is even higher than REF, so that's out.  For the money I'd opt for the REF pieces but I just can't get my car down to AZ anytime soon.

At this point I'm leaning toward the OEM FoMoCo 427 cast iron manifolds since my build will not look very exotic and I shouldn't have any fit or clearance issues with those.  I have found a couple pairs for sale ranging from $2000-2600, each had a busted ear.  I don't see many for sale at the moment...for those of you guys that are running these, what is considered a fair price for these guys in good shape?

Ever considered building your own headers?  If you can weld (gas, MIG, or TIG) you can do it yourself.  Buy the collectors and the mandrel bent tubing, then cut and fit the tubing with a bandsaw or hacksaw to make the header tubes.  Weld them all up, and get them ceramic coated.  It's actually kind of fun to do, and you'll have a great sense of accomplishment when finished.  Lots of people are scared to try this, but its not that hard...

Another option for doing your own custom headers - there is a company here in Minnesota, Stainless Headers, that has a system where they send you some special adjustable elbows, and you add pvc pipe to mock up what you need for headers on your car. Then you send in the complete mock up prototype and they weld up a set of custom stainless headers from that. I don't personally know anyone who has done it, maybe someone here has experience? Here's a link to their website with pictures, scroll down the page a bit to see how it works.

I just built mine using flanges from Blair, 1 7/8 and 2 inch universal kits from Heartthrob, collectors off Ebay and had a local business finish tig weld them after I had tacked them the way I wanted. I have about 1000 bucks into them without any heat coatings. I might try Eastwoods inside coating and VHT flameproof outside with some header wrap to keep heat away from my starter and steering Ujoint. Kind of neat to build your own but a hoist would have made it much easier.Jim

[cjshaker]

Nice work, Jim. Those look good.
I've found that a flat sander belt, or disc sander really comes in handy for adjusting angles slightly on the tubing. Gaps need to be really good when you're tig welding, and even mig welding when using stainless.

[N2950H]

I really had no idea there were some build-your-own-header kits out there, so I appreciate the info.  I imagine it's going to be several months before my motor is complete so I have some time to sort this out. 

And Jim, those look fantastic.  That's got to be quite satisfying.

Yes sir! Nice work Jim. Blair's flanges are damn nice to work with too.
