Ok fix it. And added a photo.
A BIG thanks to CNC-Dude for helping me get the flanges re-drawn. After I lost the initial drawing, he was a big help in getting the flange re-drafted.

What size header are you considering. I looked back at my original file drawing, and these flanges can easily accomodate up to 1-5/8" tubing if you need to go that large. If you need larger than that, I can modify the drawing to fit whatever size you need, and give it to Stephen so he can cut them for you.6cylfever":3t8w0hwc said:I just got a 250 crossflow and would be interested in a header flange. Are you using hot roll or cold roll steel. Will it have enough meat around port holes to enlarge? Are you concidering a intake flange? The injection set up on my engine may not clear the hood and I might have to make my own intake.
Stephen I haven't torn down my engine yet. The exhaust ports don't look very big. I see your from Ohio, I'm asnowbird in AZ right now but will be back in Mich in two weeks. I'll tear down the engine there and get back with you than Marv'68falconohio":2ebkna8w said:The mild steel I'm using is Hot Rolled, Pickled and Oiled. Stainless steel(304SS) is also an option if anyone wants it. I know you guys want to know a price per flange and I do too... I'm still waiting on the cutting house to give me a price per piece. I have a meeting with them tomorrow to discuss other work(employment), they should have it for me then. Once they give me a price, I'll give everyone a little bit of time to decide whether or not they want a flange and how many before I get a batch cut. I intend to cut 2-3 extras for crossflow guys that come about in the future. They are swamped right now with work but promised to work me in.
Intakes are definitely an option if anyone is interested. What I need from the folks wanting intake flanges are:
1) A rubbing or drawing for the injector scallops(dimension and location reqd). The head that CNC-Dude cnc'd for me was a carby head; there were no scallops and I don't own an EFI head to look at/check fitment with. If anyone has .dxf of the EFI head that they're willing to donate to the cause that would be just as good, if not better. I'd like someone with an EFI head to confirm that the flange I cut fits the head properly before I cut a batch. Rather than make everyone port the flange a bit to make it right, I'd rather it lined up correctly from the go. (XFlow', PM me if you can do the rubbing and I'll give you an addy to mail it to.)
2) What diameter do you want the port hole to be? I havn't had the time to check what standard tubing size is offered/what would be best. I would prefer to make the flange suit a non-ported head and the end-user would be required to port it for larger sized tubing if porting has been done. I think that makes the most sense for everyone.
3) Spec carby or EFI. I doubt the Carby guys want the scallops cut out in the flange and vice versa.
6cylfever, how much meat do you need around the port? Intake and exhaust? I don't have the revised .dxf in front of me right now or the sample flange we cut. The cutting house has my crossflow head and the demo flange. Some punk has my laptop that was stolen a few weeks ago with the majority of my work on it so I can't check. IIRC, there's at least 3/8" addl. radius around the ports, if not more. I will check on that and report back, if more is needed to satisfy everyone's setup it can be done, I just gotta know what everyone needs.
School isn't taking up any of my time anymore so I have a lot of free time right now...I may be leaving for some pipeline work soon though.
