Reply to "Throttle Cable style"

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?
