General Information Post.

All the production Ford Motor Company U.S.A Ford Fairlane 221, 260, and 289 c.i.d. V8 engines made before about the late 1966 model year were manufactured in Cleveland, Ohio, U.S.A. and not in Windsor, Ontario, Canada.

Specifically, all High Performance 260/289 assembly line engines 1962-67 were manufactured in Ford Motor Company’s manufacturing complex in Cleveland, Ohio, U.S.A.  All original equipment new leaf spring chassis Cobra engines were “Cleveland” engines if one just has to cast them into a lump into one category.

There was no such thing as a “Windsor” small Ford V8 engine during new leaf spring chassis Cobra production based on all data collected to date. There were subsequent issues of 289, 302, and 351 c.i.d. V8 engines manufactured in Windsor, Ontario, Canada that were then actually “Windsor” engines. 

Beginning in late 1966, thank you Bob Mannel for the clarification, Ford started producing 289 c.i.d. engines in Windsor, Ontario to join production from Cleveland, Ohio. Afterwards, Ford started making a new 1969 model year 351 c.i.d. engine in Windsor, Ontario but the “Windsor” colloquial name did not exist yet. During the year 1969 Ford introduced another new for the coming 1970 model year design 351 c.i.d. engine. Two very different engine designs with the same displacement and two different factories to make them. After the second new engine production started, the first model made in Windsor became known colloquially as the 351W model with W meaning it was produced in the Windsor, Ontario facility. The second design created for the upcoming 1970s model year was colloquially called the 351C model where C meant they were made in Cleveland, Ohio. It was confusing in 1969 and I recall the types of questions we asked the local Ford dealer at the time.

Somewhere along the line, authors started calling all the Ford Fairane 221/260/289 c.i.d. engines, "Windsor engines” which of course was not ever true.  It would be more appropriate to say Cleveland production of 289 engines was joined by production in Windsor late in 1966.


Thanks again to Bob Mannel who helped with this timeline. Additional details are included in his excellent book.


Here is a screen grab image of a cast iron Ford 289 intake manifold casting produced December 13, 1963. You might find one with that date in a new Cobra completed during late 1963 or early 1964. (Ford Fairlane series engines were painted Ford engine satin black before the 1966 and not this custom color.)

Cobra (Thames Ditton) Forum / 2023 Blue Ridge Soiree Cobra Tour
« on: May 17, 2023, 15:48:47 »
This past May 7 through May 11 Tom Cotter and Jim Maxwell hosted another back roads of America driving tour. This year’s tour included a number of 1965-67 GT350s as participants. We had eight Cobras, three 427 Cobras, one 289 Sports that was purchased by the owner’s father new less engine and transmission new and completed by Holman-Moody in a 427 Cobra style configuration, two 1965 MUSTANG GT350s, three 1966 MUSTANG GT350s, and one 1967 GT350. One of the 1965 GT350s has been in one family since new.

The event called the Blue Ridge Soiree Cobra Tour 2023 included about 750 miles of driving spread over four days along the Blue Ridge Parkway. (North Carolina USA with very short time periods in Tennessee and Virginia.) Altitudes driven through ranged from a low of 1,300 feet above sea level to a little over 6,000 feet.

One of the rest stops along the mountain ridge. AC Cars vehicles wise from left (in the distance) to right (closest to viewer) with some of the longer away from homes mentioned: CSX3204, COX6126 (transported from New York), CSX2045 (transported from Washington State), CSX2551 (trailered from Montana), CSX2321 (trailered from Missouri), CSX2490, CSX2401, CSX3245, CSX3139, CSX2177, and CSX2181 (transported from Kansas). CSX2497 (trailered from Ohio) was also part of the tour but had not reached the car park yet as Shaun and Sue Lowry follow tours with tools to help anyone that may suffer a breakdown during the drive sections.


Sunday evening started out with rain and it rained briefly Monday morning before the day’s driving but over all the weather was great and the parkway had not filled up with summer season tourists yet. Most of the drives were under 35 mph or 45 mph speed limits through the park. (None of the cars dissolved in the rain Monday evening.)

Shameless self-promotion, our red car CSX2551, during a stop. Yes, the tour was FUN!

CSX2001-CSX2589 Cobras and potential clutch system parts compatibility issues.

If you are working on an original CSX2001-CSX2589 Cobra and the car has problems with getting a clutch system back together or it has operational problems, you might want to be aware of some technical topics. All manual transmission American market CSX2 prefix chassis Cobras, which was all but sixteen each late cars (one prototype and fifteen production cars) and one prototype car used with a FE engine, were equipped with some variant of some model year five bolt bell housing design 260 or 289 c.i.d. engine. The vast majority of these cars came with 1963 or 1964 model year 289 High Performance engines.

In no particular order:

1)   Engine cylinder block assemblies of the five bolt design bell housing type must use the clutch release lever made for 260/289 five bolt design original engines. If somebody installs the design of lever introduced for 1965 model year 289 six bolt engines, the clutch system will not work properly as the functional lengths of features are different. I have been contacted a few times over several years where this was a problem when the installer was not aware that not all levers were the same functionally.



2)   Pilot tips of factory original equipment Borg-Warner T-10 transmissions for 260/289 engines and any Ford FE engine are different with the big block model gears having shorter pilot tips. If a input from a FE engine transmission is used with a 260/289 engine, a special pilot bearing is required to capture the tip of the input shaft.

3)   Some Cobras, street and race, used a gear set with an input adopted from a General Motors version of T-10 transmission. The spline count is the same as the Ford part but the diameter is different. A clutch disc assembly designed for a Ford 260/289 engine of any version alone will not fit!


K (high nickel) set = installed into aluminum cased Cobra transmissions, street and race, introduced sometime in the CSX22xx range it is believed, example CSX2246 had a K set originally, our black car CSX2310 was fitted with a K set. (The K gear ratios originated in some high performance GM cars.) Listed as the alternate gear set in the February 1964 Cobra reconfirmation of registration for roadsters and coupes with the Fédération Internationale de l'Automobile (F.I.A.) race sanctioning organization. Application Notes:  1) The Ford 289 High Performance clutch disc will not work with the K set input. A disc that will work with the GM input is required because the outer diameters of the Ford and GM splines are different. I used a McLeod® part number 260240 disc in CSX2310 and it has served very well for decades. 2) The pilot tip of the GM design input shaft is smaller in diameter than the O.E. Ford T-10 transmissions and that requires the use of a suitable pilot bearing in the rear end of the engine crankshaft.


4)   Not a parts compatibility issue but something to consider, a COBRA lettered cast steel safety bell housing (a.k.a. scatter shield).  After seeing pictures of what happens when there is a flywheel or clutch failure in a Cobra using a stock die cast aluminum bell housing, I have zero interest in sitting in a Cobra with the engine running without a safety bell housing in use. The COBRA lettered models, there were several slight variations over time, are wonderful THE FIRST TIME they have to contain a problem. I have seen the aftermath of a flywheel / clutch failure in a friend’s race car with a tachometer tell tale indicating the engine was running over 9,000 rpm when the failure occurred. The driver was not injured. The car chassis was not damaged. The engine and transmission were both seriously damaged, but all the major projectiles were contained. The COBRA housing did not fracture anywhere but it was deformed seriously and deemed not useable anymore.


Safety Housing Side Bar: The manufacturer also sold the same design with “WEDGE” (one of their trade names) or “TIGER” lettering. Other companies made their own versions of safety housings in cast steel for five bolt bell housing engines that work fine in original Cobras.


How about COB/COX60 prefix leaf spring car chassis? Based on records available, most of the cars used five bolt bell housing design engines. Some late cars used six bolt bell housing design engines. It would be important stock parts wise to use the correct lever for the type of cylinder block design used.

Wanted To Buy: I am searching for a cast aluminum generator sheave with integral fan for an early Cobra restoration. An original part preferred but an authentic copy would do.

The original for CSX2034 is shown below.



Thanks for looking.

Cobra (Thames Ditton) Forum / Wanted: Weber Carburetor Parts
« on: July 26, 2021, 14:01:43 »
I am working on repairing a mid 1963 COBRA 4-2V induction system using Weber 48 IDM5 carburetors. The system was handled and stored poorly for decades. I am looking for quite a few very rare parts. Please see list below. I have a file with some pictures and sketches available via email to help illustrate some of the parts. Reproductions of all the parts have been made or are being worked on but I would rather have original 1950s-1960s Weber parts.

Thanks for looking. Dan

If you own or have access to an unrestored, substantially as built, with its original engine, and original engine mounted fuel pump car before CSX2126 we (me mostly but others are interested and helping) would like you to help add data and pictures to a database.  We are working to collect data on the pump’s manufacturer, casting numbers as applicable, casting dates as applicable, assembly dates, finishes, and fittings.  Real good pictures of the installation in the car would be great to have also.   Maybe you know where an original engine with fuel pump still attached is sitting in storage or on display.

Don’t have a car or access now, did you manage to take some pictures of the fuel pump area on these cars decades ago?

The intent is to add to the open source Cobra engine notes and slide shows I share with owners and restorers.   If you have information or pictures but don’t want them public, that works for me as long as I may add your casting or assembly dates to the known ranges without tying them to you or a specific car.

Thanks in advance for any information you may add to the collection.  Send me a private message through this site if you wish to make contact.

Cobra (Thames Ditton) Forum / C4SA COBRA 4V Intake Manifold
« on: August 07, 2018, 13:31:58 »
NOT MINE. This is not mine nor am I connected in any way with the seller but this piece is so rare I wanted to make an attempt to let early Cobra owners know that it is listed on ebay®

Based on the Holman-Moody intake they created for 260 c.i.d. Ford engines in the 1962-63 time frame this version has COBRA lettering where the Holman-Moody bird logo was in the original version. IMPORTANT: This intake is functionally a copy of a Ford cast iron prototype intake for XHP-260 and HP260 engines and is not suitable for 289 c.i.d. engines performance wise.  These are rare. I have only come across five (5) of them in all these last five plus decades. It was a regular production option for early Cobras. A Holley R-2599 carburetor assembly went with the option package when ordered for a new Cobra.

Cobra (Thames Ditton) Forum / When was this award ceremony recorded.
« on: February 04, 2017, 20:53:37 »
Check out this video posted on YouTube(R). The last segment starts at the 1:43 mark. Does anybody know when in 1963 and where this last segment was taken? The date is of most interest.

Cobra (Thames Ditton) Forum / S1CS-19523-C Cobra Emblem
« on: January 08, 2017, 21:55:53 »
I occasionally get inquiries about Cobra mascot emblems from ACOC members so I thought I would share some posts I have made elsewhere.
   
   This post is a sort of 'infomercial'.
   
   During the CSX21xx chassis range a new Cobra mascot emblem was introduced into Cobra production. Sellers of emblems, especially on ebay®, offer all kinds of parts from all kinds of sources that are definitely nothing used in new Cobra production five decades ago.  For example, there were some extremely crude aftermarket emblems with double back foam adhesive tape on their backs offered by J.C. Whitney when the cars were just a few years old.
   
   One thing that has happened is confusion with the subsequent Ford Motor Company sourced part that replaced the one Shelby American sourced for new Cobras.  The new Ford part became the production part for most 427 Cobras; probably after the Cobra part supply was exhausted. Most of the many “reproduction” emblems offered for all Cobras (leaf spring chassis cars) and 427 Cobras (coil spring chassis cars), being offered like original to leaf spring in cars particular, are copies of the Ford emblem.  By the 1980s there were copies of copies of the Ford emblem being offered ‘as original’ for Cobras (leaf spring chassis cars).
   
   The slide below illustrates originals of the Shelby and Ford parts in a side by side comparison.
   
   
   
   PS If you have a Cobra and have original S1CS-C emblems but one or both pins are broken off them, don't give up as pins can be replaced.

I am helping round up parts for the restoration of a 1964 time frame Cobra Weber induction system. We need four of these O.E. cast brass banjos. The bolts and gaskets are not difficult to find but original banjos are. (We know that there are reproductions available. We have some but prefer originals.)
   
   Thanks for looking.

E. Weber carburetor models 48 IDA and 48 IDA1 were nearly the same. The difference was in what type throttle lever, throttle stop screw spring, and throttle stop screw were used in the assemblies by Weber. Just looking at the screws and springs nothing is obviously different on the car. The throttle levers are significantly different. I am looking for two sets for some IDAs and two sets for some IDA1s. (I have purchased some current production 37s but they are different than the 1960s parts. 48 IDA4 and 48 IDA4R models used a different design without the ball pivots.)
   
   Thanks for looking.

Cobra (Thames Ditton) Forum / Wanted Wiper Switch Special Washer
« on: October 03, 2014, 01:05:25 »
I figured out why the windscreen wiper switch in CSX2551 slops around so much, it missing a special washer with sharp points that catch in the aluminum dash panel material. Does anyone have an extra they would part with?
   
   The pictures are of parts borrowed from another Cobra for photos. Thanks for looking.
