S1MS intake - pics

The intake is most likely an original

65 Shelby used after the first 100 cars

or so. Looks exactly like the one on my 65.

Unlike the large letter intakes, the small letter intakes were not reproduced (to the best of my knowledge, and have been around a while). You can trade the intake for a large lettered intake and a negotiable sum or parts on the side P.M. for more details, I feel like I'm making enemies today.

I didn't notice the small letter cobra, price++. One recently went for around $1000+ on ebay and another without the letters went for $450 http://cgi.ebay.com/ebaymotors/ws/…em=280049437985

Definite premium over the std large letter cobra

Hi 66GT

Bo is right , they used that intake on 289 Cobras and early 65 Shelbys.

Hi 66GTK

The 289 Cobras and early 65 Shelbys did not have the SiMS part number on them. Then like Bo said then they used the part number on them. The 65 Shelby 715 cfm carb just had the list number and date code on the air horn on the front of the carb.On the 66 Shelbys they put S2Ms on the air horns of the carbs.

My two cents:

Very few 289 Cobras had the 715 and small letter Cobra intake. (I think the real number is under 5). THe earliest version of the 3259 is dated November 1965) All of the cars built in California for street use had to have a PCV system, the small letter Cobra intake had a pcv fitting on the back of the intake. An intake that does not have the PCV fitting was intended for the R-Models. Unmolested, these intake manifolds bring 1 to 2K.

Another thing, I would like to see that manifold go to someone who actually needs it for a car as opposed to someone who is going to turn it for a huge profit. I don't need it since my car has the correct small letter intake. An early dated carb would be a different story. <img src=images/icon_smile_big.gif border=0 align=middle>

Per the 1997 SAAC Registry just three very late finished Cobras came with a high rise intake and Holley carburetor. See the my picture post under the carburetor thread.

"November 1965"....I think you meant November 1964. There was, based on the ones found, a run of List-3259 units right after Christmas (4B5 date) 1964 that got used in production and Cobra CSX2555 was one of the cars that left SAI with one, I have CSX2555's carburetor. These early units have different parts than ones made just a month later. A couple of us have started a data base of casting and engineering numbers for individual parts when we find carburetors that have never been mixed macthed by owners / restorers. Some of the parts in an early List-3259 are the same ones used in an earlier List-2668. There were at least two main body castings for List-3259s and two at least for List-3259-1 by 1967. Holley's detailed break down lists several revision levels of the design just in 1966.

If you look at the intake picture you will notice the holes of the carburetor studs are offset to the rear. You can not just put a carburetor on this intake and use it, the throttle plates hit. I have seen just three of these and only held two in my hands. Two of them were removed per the seller from one of the three Cobras using them when some other induction system was installed. CSX2555 got a late 1967 version of the Holley 2-4V system when my carburetor was removed from it. All three of these really thin wall (can't be ported) intakes I have seen had the holes offset to the rear. I was told by one of the people that removed one of these intakes that there was a PCV spacer, a real thin one, that was wedge shaped between the intake and carburetor on the Cobra. I have no idea what that spacer was but I found a Ford phenolic one in junk yard that would do the job. With a thin spacer the throttles will open.

I had one for my Mark Donohue R-model replica I'm building but sold it to a friend that had an original '65 GT350 car with a tri-power set-up.

My car wasn't done and his was nearing completion so I let him have it for what I had paid.

Now my car is nearing completion and I'd like to have another. I have two orig '66 large letter intakes but no '65's. If you're interested in a trade or outright sale let me know. I don't sell my parts except to friends for dedicated projects and always prefer trades.

This would be dedicated part for my car, not a resale piece.

Thanks,

Mark
