I am planning on replacing the throttle cable from the peddle to carb. My PLAN is to find a cable with the return spring built into the cable, which should relieve most of the stress on the carb shaft and bushings. Has anyone been able to find such a cable? I have inquired at push/pull but got no replies.

Thanks,
Angelo

Do you mean a cable like this?
I believe it came from Wilkinson.
I believe the sleeving is green.If you need more pics let me know.
This car uses a light spring on the carb also as a back up.

possibly. More pics would help. I did not think of a backup spring, but I could see why I guess. I have just found that a cable set up like that seems more responsive and easier on the shaft of the carb over time.

Thanks for your reply,
Angelo

Here is a close up of the cable ends.
They use the screw on pieces to attach to the ball studs on the carb and gas pedal.
Because of the tight turn at the front of the motor the cable has tension and the spring doesn't move as free as it could. You might have to shim it for more tension. Pay close attention to your travel limits. The cable does not have a lot of travel.

Brooke,
I have the same replacement cable as a spare. The current cable appears to be the OEM. Throttle works fine but the thought of taking the stress off the carb linkage is good advice.

Any special install thoughts ? And where are you shimming for the additional tension ?

PS:
Not to be a wise guy but is that a Fram oil filter on your engine. I have never heard anything good and lots of bad about the quality of Fram oil filters. The Ford FL1(?) is rated much higher and they cost the same as Fram. I run the K&N.The filter is well rated and has a nice 1/2" nut welded on the end for easy removal.

Good eye 4134!
That is not my engine. That is a car I was working on.
You'll notice that there are no headers on the engine either it was getting GTS headers and they hadn't come back from Jet Hot. Thats why you can see the filter.
I did change the oil and filter before it left. I did not use Fram.

A pic of my engine is in the timing pointer thread.

As I think about this scenario Im wondering about the application of forces on the throttle shaft and Im not sure in a pulling application like in a pantera that there would be stress on the shaft. You are pulling inline with the springs resistance and not against the shaft like in a normal car where the shaft acts as a pivot on a see saw between the linkage and spring.
I was also told some time ago that the reason in a normal car it is better to hook the spring on the top of the carburetor arm where the linkage attaches and run the spring forward on the intake. This looks stupid but it is also supposed to eliminate stress on the throttle shaft by removing tension opposite the pivot.

Any Engineers out there? What do you think?

I dont care about his oil filter. What I want information on is those transparent headers. Do they flow better? How is the heat?

That cable looks good. And it looks like the spring tension is adjusted by the spring end cap near the carb connector.

Wilkenson you say?

Thanks

I have the same looking cable on my car. It came that way when I boght it.
Every aftermarket part on my car cam from Hall Pantera, so perhaps they have this cable as well.
