1955 exhaust manifolds I have had for years. Got them at a swap meet trade. These are the 2nd design in very nice shape with the original heat riser still intact. $125.00 plus shipping. Thanks all. Troy.

so, someone pointed out that these manifolds might not be for a corvette. well i again looked them up in "CORVETTE BY THE NUMBERS" and they are for SURE for a 55 corvette. now, there was a first design and a second design. and i have not been able too find a cut off for the change as far as casting numbers and dates go.. i did not see any date castings.. i know i just told someone on the site i would take 150 for them. but i had forgotten what i had originally listed them for.. so $125.00 OBO thanks troy
First I recognize that you have far more knowledge of these Dinosaur years ('53-5) by leaps and bounds than I will ever have.
You are right I should have said his 3837069 manifold where I said 3704791 is a manifold that may have been used on late '55 Corvette as well as '56 passenger cars. Please school me here. Were either of the second design manifolds 3837069 & 3728750 ever actually used on a late '55 Corvette?
I am aware that Flint and Tonawanda both cast the 3704791 manifold and they do differ. Also that the Flint manifold has a strengthening rib above the dump.
Can you shed light on the R.H. manifold # 3711634?

Flint and Tonawanda have the same castings except Tonawanda uses a date code. In May of 55 both Tonawanda and Flint changed to the rib style manifold. In September it appears that Gm attempted a casting change with 3837067, but failed. This is a one week only casting that is replaced by 3837069. # 3704791(no rib), 3704791(ribbed), 3837067 and 3837069 can be found on 55 corvette's driver side. The 3837069 will be verified when information on 55 #699 and #700 is released.

The 3837069 and 38369968 will be verified when information on 55 #699 and #700 is released. The 53-55 judging guide does not say how they come up with a lot of their information so how they came up with #3728750 is a mystery to me. They need to have a keynote on the car that they are using as a reference.
The only thing I can say for sure, is that Scopeli is "The Man", when it comes to '55 Corvette parts knowledge.
Looking over notes on #699 and #700 I can only verify the driver side manifold being #3837069. I will have to check other late 55 corvettes for the #3836968 and #3728750.

I did not recognize #3711634, but I see it is listed in my 53-55 parts catalog and the 55 chevy part catalog as the RH manifold. The parts catalogs do not have casting number #3704792 so evidently when you ordered part #3711634 you get casting #3704792. In the 56 catalog, #3711634 is replaced by #3728750. #3836968 that replaced #3704792 is not listed in the 56 catalog. It appears that when you ordered #3728750 you were getting the RH manifold with casting #3836968.

ok i am really confused! what manifolds do i have then? i searched the numbers on mine from "corvette by the numbers" thats all i had too go on....so please tell me what mine are if you could...are they worth anything? or just scrap? thanks troy
Hope the "date" censors let this one through LOL
FYI here is a '55 ? left side exhaust manifold I have finally cleaned up for your perusal / comment gentlemen.
Is that the "rib" that is referred to - on the back of the mnfld above the outlet flange ?
