R/3 exhaust manifolds?

[jtjim]

I have a set of origional R/3 exhaust manifolds. They were on the engine when I bought this R/1 engine back in 1973. It also has the double breather valve covers. It is definately not an R/3 engine. I rebuilt it many years ago and will be using it in my "53. This will be a driver and I don't think I really need high performance manifolds. I am wondering what these would sell for. Maybe they would finance the rest of my project!!! I have been watching for some time but haven't seen any for sale. Any help?

Studebaker International has new ones in their catalog @ $385.00 a pair.

I've seen orginals sell for slightly more. The big difference between the repops and originals is that the originals have a part number on them whereas the repops have a boss pad with nothing on them. I don't think you can even see the part number on them when they are installled and in the engine bay.

Selling them would buy you half the paint (in cans) for your 53 project.

I am sure someone will correct me on this, but I thought Studebaker originally offered a right side header with the support for the alternator for Larks and Hawks, as well as the type Stude International has available, which is the Avanti Style. I am getting old and senile, and thus could be wrong, but if this is the rare Lark/Hawk style, I think they would be worth big $$

So, WAS there a Lark/Hawk style originally?

[R2Andrea]

Yes there is/was a correct right side header that incorporates the mount for the alternator bracket. This was necessary because the R3 style headers were offered as an option on '64's with the "lesser" engine options. Whether or not any were equipped that way at the factory is another story. When I was going through the '64 production orders I was able to find cars with headers ordered but they had all been x'd out. The headers will be available in the not too distant future with the bracket mount cast in place.

[jtjim]

These headers have the alternator mount cast on the right header. Any Idea how much they might be worth? I also have the exhaust header pipes for this application.

Okay I am confused. You guys keep talking about headers, but the picture you have posted is of a cast Iron exhaust manifold?? This looks no different than the one on my wifes 61 Hawk. With the "Generator mount" cast into the manifold.

Hi, Brian,

Yes, at a glance, the R3 cast iron "headers" appear similar to the standard.

No, the R3 exhaust manifolds are really not that more efficient, but in the microcosm of Studedom, tiny differences assume great importance.

Maybe, someone has a sideview photo which will show you the differences.

what are the #'s cast on the manifold?

[3x2stude]

I am wondering what the ID of the exhaust port is on an original? Can you measure and / or snap a pic?

I believe they are the same as a stock 570 head.

[R2Andrea]

The casting numbers are 1563086 for the right side Lark / Hawk application and 1558353 for the others. The ports on the head end are the same size and shape as the standard manifold. The outlet dia. is 1 7/8" which should be the same as well.

Brian -

Just like GM made an "iron header" for the 409.
Ford made one for the 406.
Chrysler made one for the 413 (I think).
And yea, the Studes had a set also. My opinion, they were the least advantages of the bunch, but still work a little better than the standard set.

While these weren't steel tubing, they were designed a littlesmoother (inside) thAn the normal manifold. Thus the reason many call them factory headers...NOT to be confused with the actual tubing headers that most of the manufacturers use today.

In some cases they worked much better thAn the standard set, in some cases they worked a little better thAn the standard set, but in all cases...they worked better thAn standard.

I had an original set for a 409 I built many years back. Even in the mid 80's they were very expensive, partly because so few were cast, and partly because they were so thin...they cracked and or just plain broke.
The Fords and Chryslers were both heavier (bigger) and thicker.
