Cobra Jet Detailing Guide
« on: January 12, 2018, 05:49:52 PM »
I put together a new guide on how to detail a typical Cobra Jet engine especially with the 50th anniversary happening this year of the official release.  This is an update of information plus adding some more new information we have not had.  The goal here was to review some of the most common items and not go into the internals of the motor.

Welcome to comments, questions or suggestions here. 

Its a long article so give it a minute to load on your screen.

Perfect.

A few comments.

In topic #2 : Its missing a J in Cobra Jet.

Under topic # 5. Just a question regarding exhaust manifolds. Did early 70 exhaust manifolds have provision for the choke stove? If not, are they different than 69?

Topic #18. Are distributor brackets the same all years/California emission?

Marcus. You realy have to write a book!

Thanks for what you do and share with us.

The original C8 motor mount insulators I have seen have a red ID stripe. Im not sure how long they continued use of them......

1968 Shelbys have a few other variants as well.

Thanks for sharing this information

Great in depth article . The best yet IMO.  I saw a typo in #8 Engine tag was commonly placed under "coil bracket " bolt . You had dist hold down. #14 FYI the silver color on the valve cover gasket was a sealer . #32 the more common trademark on the bell shaped sender for 69 was FOMOCO in block letters in the rectangle. The Ford script version was less common IMO.

I posted this over on the CJ forum, but thought I should include it here as well...

Awesome document, Marcus and Bob!

Noted a few typos, missing(?) info, and possibly some corrections to be made?  Not criticizing, just trying to help - and gain a better understanding of these details.

Pg 6, #18 - "Distributor bracket" - I believe this should be Ignition Coil Bracket.

Pg 7, #21 - the picture on the right shows a D0ZF-AB carb, but the text beneath the picture describes the 1968 carb in the other pic.  I think the '68 carb image may also have lost some of its text.

Pg 8, #22 - I have my original D0 motor mounts, if you want any pics.

Pg 8, #23 - no mention of the different versions of CJ oil pan (C8 and C9) and how they can be identified externally by the baffle spot welds?  Also no mention of the windage tray and its variations?

Pg 9, #27 - Alternator fan blade change dates don't appear to match between the text on the images and in the description text.

Pg 10, #30 - wasn't there also a 1970 spacer version that had 4 holes, instead of the double "kidney bean" shapes?

Pg 11, #34c - Aren't BOTH brackets in the picture used for the alternator?  The smog pump adjusting bracket is not pictured, but it is mentioned in the text.
Pg 11, #34e - text seems confusing to me... "...except those with AC that had an additional bracket as shown here above."  I get the gist of the washer spacer, but what is this additional bracket that's mentioned?

Pg 13, #38 - this describes the 1969 starter cable mounting.  Do you plan to add the 1970 starter cable mounting info?

That's as far as I've gotten ~ time for bed.  Can't wait to finish reading the rest of it though!  Wow!

Finishing reading, here are a few other things that caught my eye...

Pg 15, #45e - "The oil cooler bracket was held in place with two special brackets..." 

Pg 15, #47 - just me being a picky editor, but I think the image with the fuel pump date code should have the text portion in the same order as the stamped number, for a more direct correlation.  "9M8A" stamp / "1969 Dec 8 First Shift" text.

Pg 16, #50 - the C9ZE-E fans have no date code?  Mine has a "27" and "u" (greek Mu) stamped in one fin.  Is this some sort of inspection stamp and not a date code?  Or is mine stamped because it was a service replacement?


Ok, that's all I got :-)  Thanks for the excellent article!

Great story. It is amazing how many experts won't share what they know. This site has plenty of knowledge to share, and willing to. I am glad I am part of it. Everybody keep up the GREAT work.

This is a fantastic document! It's going to help me quite a bit, I do have some suggestions though, mostly grammar. Under number 11, it should read, "There were two basic versions..." same applies to changing was to were in the first sentence in numbers 27, 37, 45a, and 50. Also, could a section be added indicating how much of the engine was assembled that received paint and/or parts that are clearly painted along with those that aren't plainly obviously painted?

I updated the link now to version 1.1 at the beginning of this thread with changes and edits.  Let me know if you see anything else in here....certainly appreciate everyone's input and time reading something this long.  Next time I will have to do a 6 cylinder detail article to make my life easier.

Great effort as always. Know how hard it is to keep these articles from growing out of hand as one details is related to another and then another.

Might have added more white space - balance is off from the viewers point and information can look crowded as the eye naturally moves from the top left to the lower right corner of the page and pictures (and in turn details) get smaller because of the lack of space and balance.  Just an observation and something that was stressed in my education related to design and layout. Ya my department actually sent me to school for that sort of thing  ::)

As an example of one details creating a need for another would be the hose style shown in the PVS pictures. Some may assume that all of the CJ's can with or are correct with the MX marked hoses.

Another detail. Does it look like the attaching bolt heads for the bellhousing to engine are painted in the picture on page 18, Item #58. Seems that if the intake was sprayed and the bell housing below the visible (top side and rear face) part of the bolts and washers would have engine paint on them. Should be able to PhotShop those in to make that go away   ;) 

Keep up with the good work and thanks for sharing it here on our site

Thanks Jeff.  Points well taken there. 

Of all the things the spacing was the most difficult.  I could write this twice as fast if I didnt have to worry about spacing.  Need to plan the pages out and move things around.  Wish I had someone else doing all that for me.  But the most important of it all was to have clear updated photos.  Nice clear pictures are everything for a detail article.
