Anyone interested in OE style 2.5" ram horn flanges? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I put a pair of 2.5" outlet Vette ram horns on the '68. I'm wanting the OE style formed flanges that attach the pipe to the manifold. All I can find readily available is the 3/8" flat mild steel that are prone to warp bad. I did find one place that found a box of 5 sets in a warehouse, but they will only sell the whole box to get rid of them. I haven't been quoted a price yet- should know Monday.

Assuming the price will be fair, anyone interested in the other 4 sets?

i'll try and remember to check on monday when i go back to work and see if we still have any hanging on the wall. as far as i know, they are still available through our muffler suppliers. in case i lose track of this post, p.m. if i don't to contact you by monday evening.

Thanks- that would be great!

All the parts store/ Walker/ ETC I've found are the flat style.

I might be interested...pending pics/measurements & prices. Some of those fit OK & some don't.

Exactly. I don't want any cheap flimsy junk either. I'd like to get this exhaust done soon- pulling it in & out of the garage with open manifolds isn't really as fun as actually driving the darn thing. It has been held up too long searching for some stupid flanges

Shouldn't a big block be the same or are you talking about the manifold pipe?

jeffspower · 07-26-2008, 11:05 PM

I think the stud- to- stud spacing is bigger on a BB. I need 3" stud/ stud. My '88 454 has '96 manifolds on it- I'll check it tomorrow- I think the studs are further apart than the old BB stuff. Anyone got an old 454 manfold to check?

I'm interested if the price, and quality is right

**jerry moss** · 07-28-2008, 10:42 PM

i checked today at work and we are out of the stamped flanges so i called our largest suppliers and they don't stock them anymore either. all they have are the flat style, but, they do make the flat version in 3/8" thick.

jeffspower · 07-29-2008, 07:14 PM

Jerry, thanks for checking. The guy told me today that "the warehouse showed them in inventory, but when they went to the shelf to get them, they were not there". So I may have no choice other than the flat style.

I sure would like to know how guys pull of perfect & correct restorations. These flanges would be OE on a Vette, so I find it hard to believe somebody isn't making them. Seems like I run into impossibilities on the simplest things

Will do. I'm still a noob to the St. Joe area. Moved here from NE 4 years ago- to the day. I might swing buy your shop in the next few days- I need to stop in at Bolin's for some stuff for work.
