Just as a point of interest, I mention this.

On my '68 GT350, I bought a set of JBA long tube headers "theoretically" built for that year car.

When I installed them, the car could not turn left. As it turns out, the Pitman arm would hit the #5 tube and restrict it from the necessary distance necessary for it to move to turn the wheels left.

In discussing this with JBA, it seems that they built the headers on that chassis that used a different Pitman arm.

Now I did try to discuss this intelligently with the design tech, but some might argue that is a bridge too far for me, but the comment from JBA was that my car uses a "special" Pitman arm?

So that's what I know and the "Special Bus" just pulled up for me so I have to cut this short and run to catch it.
This is getting of track some but regardless of what JBA said your 68 GT350 pitman arm is the same as a regular 68 V8 Mustang equipped with P/S pitman arm. Now back to 66 related stuff  ;)

I was going to replace my late 66's idler arm. I see some sites have a standard arm assembly while others have the 66 Shelby arm as a quick steering arm. Did all 66's have the quick steering as delivered by Shelby? Just want to make sure I order the right part.
65/66 Shelby's had the quick steering longer arm. Other year Shelby's and regular Mustangs did not.

1967 Shelby GT350/500 / Re: 1967 GT500 Oil Filter Adapter Question
« on: March 26, 2024, 04:36:53 PM »
so they are all correct? I thought that in 67 they only had a fomoco logo in the oval. Do you maybe have an idea why some have he Sheffield and others the FoMoCo Logo? I think this adapter was used from the beginning of the FE until late 67. I have seen several different ones but I thought there is maybe something like a guide which ones were produced when.
If by correct you mean used on a 67 GT500 then typically there is a date code (year number and month letter) that is metal stamped into the flange that gives a idea of time frame usage .

i have several Oil Filter Adapter here and I would like to know which one is correct for the 67GT500 to 100%

I have seen them with Sheffield Logo and oval FoMoCo logo and without them

I would be interested to find out what the numbers mean like 8,6,1 etc. is this the year?
There are at least other examples besides the ones you posted that I have seen. I am skeptical the single number represents a date code given the ones I have found on 67 cars have numbers that range all over the map.

For what it's worth, I'll post all of the Bud Moore TA Cougar engine pictures that I have mined thru the years.

Here is Dan, Bud, Parnelli and Fran Hernandez at Bud Moore Engineering getting ready for the 1967 Trans-Am season.

Those guys are laughing about the big checks they're getting from Ford and Gurney's thinking how am I going to make this thing win.
That must be a very early production car. The battery hold down J bolts are silver zinc. It wasn't long after production started that they changed the finish to zinc phosphate.

Might be a camera angle thing
It still looks different. At least to me . I only had a original Hertz wheel to use as a comparison . For those reading the chrome hertz wheel and the painted wheel were the same rim just one was chrome for the Hertz GT350 and the other painted for the non Hertz GT350.It is hard to distinguish details because of the shiny chrome so I used a razor blade I had handy to show width.

The other version I have has no ink stamp but many other markings
On the outside of the rim by the valve stem
M4 over 3 , 6 9 and a ford oval to the right of the valve stem
on the backside of the rim 92 and H with a small 3 underneath
on the inside of the rim itself
F 14x6 JK 1 V
795 M4 over 3 Made in USA and I think a backwards D
Backspacing is 3 and 5/16
The paint is a satin almost semigloss grey that has a yellow/green hue to it.
I have more than one of these all the same
Regardless of color the picture in reply#1 does not look like the proper front side rim profile for a 66 GT350.

This sure looks like my current balancer

C4AE casting indicates that it is the early casting .Not a big surprise that a Ebay description is wrong.  Regardless, does it make a difference if it is like yours or not ? Cobra automotive makes a repro of the 428 SCJ balancer if you want to spend the money and take the chance it will cause more vibration. It seems like it will be less money and at the least a better chance of less problems with ether the single or double cast iron accessory pulley added to your current one to line up with your water pump and alternator pulley.

Hello Bob

Thank you for taking the time to help me out

Car is a 68 C code fastback that had this motor swapped in.

I bought the car several years ago and brought it to the UK

Engine is a C scratch block. (Saw when installing a different trans)

Engine has been running and zero vibration. The car runs like a scalded car

Forgive me for my naïveté on the matter. But if the existing balancer/pulley is taken off. Is it a normal crank snout or is the hatchet weight assembly integral?

I’ve had many of these cars. But predominantly small blocks so have no experience with the hatchet weight setup

Trying to find out what would lock me into using the cast iron extra pulley as opposed to the later
68 style balancer and bolt on pulley

Thank you. Peter
Radical balance changes is what might lock you in . From the information so far it is not clear how this engine is balanced.  The sleeve with the hatchet head is the same as the typical BB one but without the hatchet and it slides off in the same way. The hatchet detail is a counterweight to help the factory to even out the balance in a nominal way for heavier rods on a assemblyline 428 Super Cobra Jet along with a different balance flywheel and larger diameter harmonic balancer. Why it is used here is a mystery to me but its use in this case suggests a interesting balance situation inside that may cause a issue if balancer things are changed.  The engine should have the same clearance with the radiator regardless  unless the engine has been moved forward maybe with motor mounts reversed or something. My concern is that with this Frankenstein setup that changing to what would be typical would make things worse not better . Yes I think all things considered to make it work with odd ball pullies may be the least aggravating solution.

Seller implying that his Motorcraft restamped distributor is for a 69 Mustang. FYI The C7AF -AA engineering number is for a Fairlane application .
 https://www.ebay.com/itm/335238612019   Restamped numbers and letters are so obvious it is laughable. You can see the partial truck part (TF) number under and between the new bogus stamp. It isn't a significant distributor in any sense but it made me laugh because it was so bad. I hope it made others smile or laugh too.

Looking for expert advice on how to add a dual crank pulley to this setup

I deal with a bunch of small block and 390 cars every year

Not run into this before. C scratch 428

What I am dealing with is  said to be a 61-67 FE balancer/pulley setup

The engine is in my personal 68FB

I  having Borgeson Installed and need a dual pulley on the crank pulley.

I have plenty of three bolt single/dual and triple pulleys

But I am told the cast one is the one I need

But others have said I can add a 3 bolt like those found on a small block

Can anyone shed any light on this?

1st two photos are my engines balancer and single I’ll do

Third is what someone recommended

Forth is what someone else
recommended

Thank you.

Peter
Has this engine been running and does it have vibration at any given speed? Not a expert but my observation is that it looks like a SCJ hatchet head counter weight sleeve from the picture and early 390 crank balancer /pulley.  If it is then it is a frankenstein set up with components that were never used together let alone in a 68 FB. I would typically advise use a 68 up 390/ balancer 428 then you have all kinds of crank pulley choices but then again I don't know how this engine is balanced given the counterweight . Without that knowledge one can only guess. You may be locked into using the single or double cast iron accessory pulley.
